Security Vulnerability Report for lollms_playground.py

This report provides an analysis of the potential security vulnerabilities found in the lollms_playground.py file and suggests fixes for the identified issues.

1. Insecure File Operations

The get_presets, add_preset, and del_preset functions are vulnerable to path traversal attacks due to insecure file operations. An attacker can manipulate the input to traverse the file system and access or modify unauthorized files.

Vulnerable Code Snippets:

# In get_presets function
presets_folder = Path("__file__").parent/"presets"
for filename in presets_folder.glob('*.yaml'):
    with open(filename, 'r', encoding='utf-8') as file:
        preset = yaml.safe_load(file)

# In add_preset function
filename = presets_folder/f"{fn}.yaml"
with open(filename, 'w', encoding='utf-8') as file:
    yaml.dump(preset_data, file)

# In del_preset function
presets_file = lollmsElfServer.lollms_paths.personal_discussions_path/"lollms_playground_presets"/preset_data.name
presets_file.unlink()

Recommended Fixes:

1. Use the sanitize_path_from_endpoint function from the lollms.security module to sanitize the input path before performing file operations.
2. Use os.path.join to safely join path components instead of directly concatenating them.

Fixed Code Snippets:

# In get_presets function
presets_folder = sanitize_path_from_endpoint(str(Path("__file__").parent/"presets"), allow_absolute_path=False)
for filename in glob.glob(os.path.join(presets_folder, '*.yaml')):
    with open(filename, 'r', encoding='utf-8') as file:
        preset = yaml.safe_load(file)

# In add_preset function
fn = sanitize_path_from_endpoint(preset_data.name, allow_absolute_path=False)
filename = os.path.join(presets_folder, f"{fn}.yaml")
with open(filename, 'w', encoding='utf-8') as file:
    yaml.dump(preset_data, file)

# In del_preset function
preset_name = sanitize_path_from_endpoint(preset_data.name, allow_absolute_path=False)
presets_file = os.path.join(lollmsElfServer.lollms_paths.personal_discussions_path, "lollms_playground_presets", preset_name)
presets_file.unlink()

2. Lack of Access Control for Sensitive Endpoints

The lollms_playground.py file does not implement access control for sensitive endpoints. This allows remote users to access and manipulate data, which should be restricted to localhost.

Recommended Fix:

Use the forbid_remote_access function from the lollms.security module to restrict access to sensitive endpoints.

Fixed Code Snippets:

from lollms.security import forbid_remote_access

@router.get("/get_presets")
def get_presets():
    forbid_remote_access(lollmsElfServer)
    # ... rest of the function

@router.post("/add_preset")
async def add_preset(preset_data: PresetData):
    forbid_remote_access(lollmsElfServer)
    # ... rest of the function

@router.post("/del_preset")
async def del_preset(preset_data: PresetData):
    forbid_remote_access(lollmsElfServer)
    # ... rest of the function

By implementing these fixes, the security vulnerabilities in the lollms_playground.py file can be significantly reduced.
