The wpa_supplicant supports certificate subject validation via the subject match(2) and altsubject_match(2) fields. domain_match(2) and domain_suffix_match(2) fields are also supported for advanced matches. This validation is especially important when connecting to access points that use PAP as the Phase 2 authentication type. Without proper validation, the user's password can be transmitted to a rogue access point in plaintext without the user's knowledge. Most organizations already require these attributes to be included to ensure that the connection from the STA and the AP is secure. Includes LuCI changes via openwrt/luci#3444. From the documentation: subject_match - Constraint for server certificate subject. This substring is matched against the subject of the authentication server certificate. If this string is set, the server sertificate is only accepted if it contains this string in the subject. The subject string is in following format: /C=US/ST=CA/L=San Francisco/CN=Test AS/emailAddress=as .example.com subject_match2 - Constraint for server certificate subject. This field is like subject_match, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. altsubject_match - Constraint for server certificate alt. subject. Semicolon separated string of entries to be matched against the alternative subject name of the authentication server certificate. If this string is set, the server sertificate is only accepted if it contains one of the entries in an alternative subject name extension. altSubjectName string is in following format: TYPE:VALUE Example: EMAIL:server@example.com Example: DNS:server.example.com;DNS:server2.example.com Following types are supported: EMAIL, DNS, URI altsubject_match2 - Constraint for server certificate alt. subject. This field is like altsubject_match, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. domain_match - Constraint for server domain name. If set, this FQDN is used as a full match requirement for the server certificate in SubjectAltName dNSName element(s). If a matching dNSName is found, this constraint is met. If no dNSName values are present, this constraint is matched against SubjectName CN using same full match comparison. This behavior is similar to domain_suffix_match, but has the requirement of a full match, i.e., no subdomains or wildcard matches are allowed. Case-insensitive comparison is used, so "Example.com" matches "example.com", but would not match "test.Example.com". More than one match string can be provided by using semicolons to separate the strings (e.g., example.org;example.com). When multiple strings are specified, a match with any one of the values is considered a sufficient match for the certificate, i.e., the conditions are ORed together. domain_match2 - Constraint for server domain name. This field is like domain_match, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. domain_suffix_match - Constraint for server domain name. If set, this FQDN is used as a suffix match requirement for the AAA server certificate in SubjectAltName dNSName element(s). If a matching dNSName is found, this constraint is met. If no dNSName values are present, this constraint is matched against SubjectName CN using same suffix match comparison. Suffix match here means that the host/domain name is compared one label at a time starting from the top-level domain and all the labels in domain_suffix_match shall be included in the certificate. The certificate may include additional sub-level labels in addition to the required labels. More than one match string can be provided by using semicolons to separate the strings (e.g., example.org;example.com). When multiple strings are specified, a match with any one of the values is considered a sufficient match for the certificate, i.e., the conditions are ORed together. For example, domain_suffix_match=example.com would match test.example.com but would not match test-example.com. This field is like domain_match, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. domain_suffix_match2 - Constraint for server domain name. This field is like domain_suffix_match, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. Signed-off-by: David Lam <david@thedavid.net> |
