EAP-pwd side-channel attack
Published: April 10, 2019
Identifiers:
- CVE-2019-9495 (cache attack against EAP-pwd)
Latest version available from: https://w1.fi/security/2019-2/
Vulnerability
Number of potential side channel attacks were recently discovered in the
SAE implementations used by both hostapd and wpa_supplicant (see
security advisory 2019-1 and VU#871675). EAP-pwd uses a similar design
for deriving PWE from the password and while a specific attack against
EAP-pwd is not yet known to be tested, there is no reason to believe
that the EAP-pwd implementation would be immune against the type of
cache attack that was identified for the SAE implementation. Since the
EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP
peer) does not support MODP groups, the timing attack described against
SAE is not applicable for the EAP-pwd implementation.
A novel cache-based attack against SAE handshake would likely be
applicable against the EAP-pwd implementation. Even though the
wpa_supplicant/hostapd PWE derivation iteration for EAP-pwd has
protections against timing attacks, this new cache-based attack might
enable an attacker to determine which code branch is taken in the
iteration if the attacker is able to run unprivileged code on the victim
machine (e.g., an app installed on a smart phone or potentially a
JavaScript code on a web site loaded by a web browser). This depends on
the used CPU not providing sufficient protection to prevent unprivileged
applications from observing memory access patterns through the shared
cache (which is the most likely case with today's designs).
The attacker could use information about the selected branch to learn
information about the password and combine this information from number
of handshake instances with an offline dictionary attack. With
sufficient number of handshakes and sufficiently weak password, this
might result in full recovery of the used password if that password is
not strong enough to protect against dictionary attacks.
This attack requires the attacker to be able to run a program on the
target device. This is not commonly the case on an authentication server
(EAP server), so the most likely target for this would be a client
device using EAP-pwd.
The commits listed in the end of this advisory change the EAP-pwd
implementation shared by hostapd and wpa_supplicant to perform the PWE
derivation loop using operations that use constant time and memory
access pattern to minimize the externally observable differences from
operations that depend on the password even for the case where the
attacker might be able to run unprivileged code on the same device.
Vulnerable versions/configurations
All wpa_supplicant and hostapd versions with EAP-pwd support
(CONFIG_EAP_PWD=y in the build configuration and EAP-pwd being enabled
in the runtime configuration).
It should also be noted that older versions of wpa_supplicant/hostapd
prior to v2.7 did not include additional protection against certain
timing differences. The definition of the EAP-pwd (RFC 5931) does not
describe such protection, but the same issue that was addressed in SAE
earlier can be applicable against EAP-pwd as well and as such, that
implementation specific extra protection (commit 22ac3dfebf7b, "EAP-pwd:
Mask timing of PWE derivation") is needed to avoid showing externally
visible timing differences that could leak information about the
password. Any uses of older wpa_supplicant/hostapd versions with EAP-pwd
are recommended to update to v2.7 or newer in addition to the mitigation
steps listed below for the more recently discovered issue.
Possible mitigation steps
- Merge the following commits to wpa_supplicant/hostapd and rebuild:
OpenSSL: Use constant time operations for private bignums
Add helper functions for constant time operations
OpenSSL: Use constant time selection for crypto_bignum_legendre()
EAP-pwd: Use constant time and memory access for finding the PWE

SAE side-channel attacks
Published: April 10, 2019
Identifiers:
- VU#871675
- CVE-2019-9494 (cache attack against SAE)
Latest version available from: https://w1.fi/security/2019-1/
Vulnerability
Number of potential side channel attacks were discovered in the SAE
implementations used by both hostapd (AP) and wpa_supplicant
(infrastructure BSS station/mesh station). SAE (Simultaneous
Authentication of Equals) is also known as WPA3-Personal. The discovered
side channel attacks may be able to leak information about the used
password based on observable timing differences and cache access
patterns. This might result in full password recovery when combined with
an offline dictionary attack and if the password is not strong enough to
protect against dictionary attacks.
Cache attack
A novel cache-based attack against SAE handshake was discovered. This
attack targets SAE with ECC groups. ECC group 19 being the mandatory
group to support and the most likely used group for SAE today, so this
attack applies to the most common SAE use case. Even though the PWE
derivation iteration in SAE has protections against timing attacks, this
new cache-based attack enables an attacker to determine which code
branch is taken in the iteration if the attacker is able to run
unprivileged code on the victim machine (e.g., an app installed on a
smart phone or potentially a JavaScript code on a web site loaded by a
web browser). This depends on the used CPU not providing sufficient
protection to prevent unprivileged applications from observing memory
access patterns through the shared cache (which is the most likely case
with today's designs).
The attacker can use information about the selected branch to learn
information about the password and combine this information from number
of handshake instances with an offline dictionary attack. With
sufficient number of handshakes and sufficiently weak password, this
might result in full discovery of the used password.
This attack requires the attacker to be able to run a program on the
target device. This is not commonly the case on access points, so the
most likely target for this would be a client device using SAE in an
infrastructure BSS or mesh BSS.
The commits listed in the end of this advisory change the SAE
implementation shared by hostapd and wpa_supplicant to perform the PWE
derivation loop using operations that use constant time and memory
access pattern to minimize the externally observable differences from
operations that depend on the password even for the case where the
attacker might be able to run unprivileged code on the same device.
Timing attack
The timing attack applies to the MODP groups 22, 23, and 24 where the
PWE generation algorithm defined for SAE can have sufficient timing
differences for an attacker to be able to determine how many rounds were
needed to find the PWE based on the used password and MAC
addresses. When the attack is repeated with multiple times, the attacker
may be able to gather enough information about the password to be able
to recover it fully using an offline dictionary attack if the password
is not strong enough to protect against dictionary attacks. This attack
could be performed by an attacker in radio range of an access point or a
station enabling the specific MODP groups.
This timing attack requires the applicable MODP groups to be enabled
explicitly in hostapd/wpa_supplicant configuration (sae_groups
parameter). All versions of hostapd/wpa_supplicant have disabled these
groups by default.
While this security advisory lists couple of commits introducing
additional protection for MODP groups in SAE, it should be noted that
the groups 22, 23, and 24 are not considered strong enough to meet the
current expectation for a secure system. As such, their use is
discouraged even if the additional protection mechanisms in the
implementation are included.
Vulnerable versions/configurations
All wpa_supplicant and hostapd versions with SAE support (CONFIG_SAE=y
in the build configuration and SAE being enabled in the runtime
configuration).

enabled since those groups are not considered strong enough to meet
current security expectations. The groups 22, 23, and 24 are related
to the discovered side channel (timing) attack. The other groups in
the list are consider too weak to provide sufficient security. Note
that all these groups have been disabled by default in all
hostapd/wpa_supplicant versions and these would be used only if
explicitly enabled in the configuration.

Unauthenticated EAPOL-Key decryption in wpa_supplicant
Published: August 8, 2018
Identifiers:
- CVE-2018-14526
Latest version available from: https://w1.fi/security/2018-1/
Vulnerability
A vulnerability was found in how wpa_supplicant processes EAPOL-Key
frames. It is possible for an attacker to modify the frame in a way that
makes wpa_supplicant decrypt the Key Data field without requiring a
valid MIC value in the frame, i.e., without the frame being
authenticated. This has a potential issue in the case where WPA2/RSN
style of EAPOL-Key construction is used with TKIP negotiated as the
pairwise cipher. It should be noted that WPA2 is not supposed to be used
with TKIP as the pairwise cipher. Instead, CCMP is expected to be used
and with that pairwise cipher, this vulnerability is not applicable in
practice.
When TKIP is negotiated as the pairwise cipher, the EAPOL-Key Key Data
field is encrypted using RC4. This vulnerability allows unauthenticated
EAPOL-Key frames to be processed and due to the RC4 design, this makes
it possible for an attacker to modify the plaintext version of the Key
Data field with bitwise XOR operations without knowing the contents.
This can be used to cause a denial of service attack by modifying
GTK/IGTK on the station (without the attacker learning any of the keys)
which would prevent the station from accepting received group-addressed
frames. Furthermore, this might be abused by making wpa_supplicant act
as a decryption oracle to try to recover some of the Key Data payload
(GTK/IGTK) to get knowledge of the group encryption keys.
Full recovery of the group encryption keys requires multiple attempts
(128 connection attempts per octet) and each attempt results in
disconnection due to a failure to complete the 4-way handshake. These
failures can result in the AP/network getting disabled temporarily or
even permanently (requiring user action to re-enable) which may make it
impractical to perform the attack to recover the keys before the AP has
already changes the group keys. By default, wpa_supplicant is enforcing
at minimum a ten second wait time between each failed connection
attempt, i.e., over 20 minutes waiting to recover each octet while
hostapd AP implementation uses 10 minute default for GTK rekeying when
using TKIP. With such timing behavior, practical attack would need large
number of impacted stations to be trying to connect to the same AP to be
able to recover sufficient information from the GTK to be able to
determine the key before it gets changed.
Vulnerable versions/configurations
All wpa_supplicant versions.

four chars of the md5sum of the SSID.
The complex manual setup should also still work, but the defaults also
now work easily out of the box. Verified by manually running hostapd

The beacon_int is currently set explicitly for hostapd and when LEDE uses
iw to join and IBSS/mesh. But it was not done when wpa_supplicant was used
to join an encrypted IBSS or mesh.
This configuration is required when an AP interface is configured together
with an mesh interface. The beacon_int= line must therefore be re-added to
the wpa_supplicant config. The value is retrieved from the the global
variable.

The wpa_supplicant code for IBSS allows to set the mcast rate. It is
recommended to increase this value from 1 or 6 Mbit/s to something higher
when using a mesh protocol on top which uses the multicast packet loss as
indicator for the link quality.
This setting was unfortunately not applied for mesh mode. But it would be
beneficial when wpa_supplicant would behave similar to IBSS mode and set
this argument during mesh join like authsae already does. At least it is
helpful for companies/projects which are currently switching to 802.11s
(without mesh_fwding and with mesh_ttl set to 1) as replacement for IBSS
because newer drivers seem to support 802.11s but not IBSS anymore.

One of the latest mac80211 updates added sanity checks, requiring the
beacon intervals of all VIFs of the same radio to match. This often broke
AP+11s setups, as these modes use different default intervals, at least in
some configurations (observed on ath9k).
Instead of relying on driver or hostapd defaults, change the scripts to
always explicitly set the beacon interval, defaulting to 100. This also
applies the beacon interval to 11s interfaces, which had been forgotten
before. VIF-specific beacon_int setting is removed from hostapd.sh.

When sta is configured, hostapd receives 'stop' and 'update' command from
wpa_supplicant. In the update command, hostapd gets sta parameters with
which it configures ap.
Problem is, with the default wireless configuration:
mode:11g freq:2.4GHz channel:1
If sta is connected to 5GHz network, then ap does not work. Ideally with
340-reload_freq_change.patch hostapd should reload the frequency changes
and start ap in 5GHz, but ap becomes invisible in the network.
This issue can be reproduced with following /etc/config/wireless:
config wifi-device radio0
option type mac80211
option channel 1
option hwmode 11g
option path 'virtual/uccp420/uccwlan'
option htmode 'none'
config wifi-iface 'ap'
option device 'radio0'
option encryption 'none'
option mode 'ap'
option network 'ap'
option ssid 'MyTestNet'
option encryption none
config wifi-iface 'sta'
option device radio0
option network sta
option mode sta
option ssid TestNet-5G
option encryption psk2
option key 12345

WPA-EAP supports several phase2 (=inner) authentication methods when
using EAP-TTLS, EAP-PEAP or EAP-FAST (the latter is added as a first
step towards the UCI model supporting EAP-FAST by this commit)
The value of the auth config variable was previously expected to be
directly parseable as the content of the 'phase2' option of
wpa_supplicant.
This exposed wpa_supplicant's internals, leaving it to view-level to
set the value properly. Unfortunately, this is currently not the case,
as LuCI currently allows values like 'PAP', 'CHAP', 'MSCHAPV2'.
Users thus probably diverged and set auth to values like
'auth=MSCHAPV2' as a work-around.
This behaviour isn't explicitely documented anywhere and is not quite
intuitive...
The phase2-string is now generated according to $eap_type and $auth,
following the scheme also found in hostap's test-cases:
http://w1.fi/cgit/hostap/tree/tests/hwsim/test_ap_eap.py
The old behaviour is also still supported for the sake of not breaking
existing, working configurations.
Examples:
eap_type auth
'ttls' 'EAP-MSCHAPV2' -> phase2="autheap=MSCHAPV2"
'ttls' 'MSCHAPV2' -> phase2="auth=MSCHAPV2"
'peap' 'EAP-GTC' -> phase2="auth=GTC"
Deprecated syntax supported for compatibility:
'ttls' 'autheap=MSCHAPV2' -> phase2="autheap=MSCHAPV2"
I will suggest a patch to LuCI adding EAP-MSCHAPV2, EAP-GTC, ... to
the list of Authentication methods available.

Hostapd's control file location was changed in 2013, and that has apparently
broken the wps button hotplug script in cases where there are multiple radios
and wps is possibly configured also for the second radio. The current wps
button hotplug script always handles only the first radio.
https://dev.openwrt.org/browser/trunk/package/network/services/hostapd/files/wps-hotplug.sh
The reason is that the button hotplug script seeks directories like
/var/run/hostapd*, as the hostapd-phy0.conf files were earlier in
per-interface subdirectories.
Currently the *.conf files are directly in /var/run and the control sockets
are in /var/run/hostapd, but there is no subdirectory for each radio.
root@OpenWrt:/# ls /var/run/hostapd*
/var/run/hostapd-phy0.conf /var/run/hostapd-phy1.conf
/var/run/hostapd:
wlan0 wlan1
The hotplug script was attempted to be fixed after the hostapd change by
r38986 in Dec2013, but that change only unbroke the script for the first
radio, but left it broken for multiple radios.
https://dev.openwrt.org/changeset/38986/
The script fails to find subdirectories with [ -d "$dir" ], and passes just
the only found directory /var/run/hostapd, leading into activating only the
first radio, as hostapd_cli defaults to first socket found inthe passed
directory:
root@OpenWrt:/# hostapd_cli -?
...
usage: hostapd_cli [-p<path>] [-i<ifname>] [-hvB] [-a<path>] \
[-G<ping interval>] [command..]
...
-p<path> path to find control sockets (default: /var/run/hostapd)
...
-i<ifname> Interface to listen on (default: first interface found in the
socket path)
Below is a run with the default script and with my proposed solution.
Default script (with logging added):
==================================
root@OpenWrt:/# cat /etc/rc.button/wps
#!/bin/sh
if [ "$ACTION" = "pressed" -a "$BUTTON" = "wps" ]; then
for dir in /var/run/hostapd*; do
[ -d "$dir" ] || continue

wlan0 got WPS activated, while wlan1 remained inactive.
I have modified the script to search for sockets instead of directories and
to use the "-i" option with hostapd_cli, and now the script properly
activates wps for both radios. As "-i" needs the interface name instead of
the full path, the script first changes dir to /var/run/hostapd to get simply
the interface names.

Both radios got their WPS activated properly.
I am not sure if my solution is optimal, but it seems to work. WPS button is
maybe not that often used functionality, but it might be fixed in any case.
Routers with multiple radios are common now, so the bug is maybe more
prominent than earlier.

This change adds the configuration options "bssid_whitelist" and
"bssid_blacklist" used to limit the AP selection of a network to a
specified (finite) set or discard certain APs.
This can be useful for environments where multiple networks operate
using the same SSID and roaming between those is not desired. It is also
useful to ignore a faulty or otherwise unwanted AP.
In many applications it is useful not just to enumerate a group of well
known access points, but to use a address/mask notation to match an
entire set of addresses (ca:ff:ee:00:00:00/ff:ff:ff:00:00:00).
This is especially useful if an OpenWrt device with two radios is used to
retransmit the same network (one in AP mode for other clients, one as STA for
the uplink); the following configuration prevents the device from associating
with itself, given that the own AP to be avoided is using the bssid
'C0:FF:EE:D0:0D:42':
config wifi-iface
option device 'radio2'
option network 'uplink'
option mode 'sta'
option ssid 'MyNetwork'
option encryption 'none'
list bssid_blacklist 'C0:FF:EE:D0:0D:42/00:FF:FF:FF:FF:FF'

uClibc makefile now automatically detects if SSP support is necessary.
hostapd makefile has been fixed to use "^" as sed separator since

Currently enabling SSP on user space depends on enabling SSP kernel

kernel modules (at least). Suggestions on how to avoid this are welcome.
Using "select" instead of "depends on" doesn't seem to work with choice

Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.
I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.
However, I can not garantee that I always picked the correct information
and/or did not miss license information.

In 2009 OpenWrt's hostapd config added an "auth_cache" boolean
to be used to address a reported issue #12129 [0] on a forum [1].
The reported issue on the ticket is different that the one
described on the forum. The commit was r33359. This change broke
proper RSN preauthentication [2] [3] [4] expectations on hostapd's
configuration for WPA2 and this in turn disabled PMKSA caching and
Opportunistic Key Caching. This change:
* Leaves the "auth_cache" to be used only for WPA networks for those
looking to use this as a workaround to a reported issue but annotates
a warning over its usage.
* Separate "auth_cache" from WPA2 RSN preauthentication, leaving
WPA2 RSN preauthentication to enabled only with "rsn_preauth" with
the expected and recommended settings.
* Adds a new WPA2 RSN preauthentication "rsn_preauth_testing" to
be used when evaluating funcionality for WPA2 RSN preauthentication
with the expected and recommended settings with the only difference
so far with what should be enabled by default to disable Opportunistic
Key Caching.
Disabling the PMKSA cache should mean the STA could not roam off and back
onto the AP that had PMKSA caching disabled and would require a full
authentication cycle. This fixes this for WPA2 networks with
RSN preauthentication enabled.
This change should be applied to AA as well as trunk.
TL DR;
The issue described on the forum has to do with failure of a STA
being able to try to authenticate again with the AP if it failed
its first try. This may have been an issue with hostapd in 2009
but as per some tests I cannot reproduce this today on a WPA2
network.
The issue described on the ticket alludes to a security issue with the
design of using a Radius server to authenticate to an AP. The issue
vaguely alludes to the circumstances of zapping a user, deleting their
authentication credentials to log in to the network, and that if
RSN preauthentication is enabled with PMKSA caching that the user
that was zapped would still be able to authenticate.
Lets treat these as separate issues.
I cannot reproduce the first issue reported on the forums of not
being able to authenticate anymore on a WPA2 network.
The issue reported on the ticket modified WPA2 RSN preauthentication
by adding two fields to the hostapd configuration if auth_cache
was enabled:
* disable_pmksa_caching=1
* okc=0
The first one disables PMKSA authentication cache.
The second one disables Opportunistic Key Caching.
The issue reported on the ticket was fixed by implementing a workaround
in hostapd's configuration. Disabling PMKSA caching breaks proper use
of WPA2 RSN pre authentication. The usage of disable_pmksa_caching=1
prevents hostapd from adding PMKSA entries into its cache when a successful
802.1x authentication occurs. In practice RSN preauthentication would
trigger a STA to perform authentication with other APs on the same SSID,
it would then have its own supplicant PMKSA cache held. If a STA roams
between one AP to another no new authenitcation would need to be performed
as the new AP would already have authenticated the STA. The purpose of the
PMKSA cache on the AP side would be for the AP to use the same PMKID for
a STA when the STA roams off onto another BSSID and later comes back to it.
Disabling Opportunistic Key Caching could help the reported issue
as well but its not the correct place to address this. Opportunistic
Key Caching enables an AP with different interfaces to share the
PMKSA cache. Its a technical enhancement and disabling it would
be useful to let a testing suite properly test for RSN preauthentication
given that otherwise Opportunistic Key Caching would enable an
interface being tested to derive its own derive the PMKSA entry.
In production though okc=1 should be enabled to help with RSN
preauthentication.
The real fix for this particular issue outside of the scope of hostapd's
configuration and it should not be dealt with as a workaround to
its configuration and breaking expected RSN preauthentication and
technical optimizations. Revert this change and enable users to pick
and choose to enable or disable disable_pmksa_caching and okc expecting them
to instead have read clearly more what these do.
As for the core issure ported, the correct place to fix this is to
enable a sort of messaging between the RADIUS server and its peers
so that if caching for authentication is enabled that cache can be
cleared upon user credential updates. Updating a user password
(not just zapping a user) is another possible issue that would need
to be resolved here. Another part of the solution might be to reduce
the cache timing to account for any systematic limitations (RADIUS
server not able to ask peers to clear cache might be
one).
