Vulnerability Data

parisneo/lollms-webui is vulnerable to authentication bypass due to insufficient protection over sensitive endpoints. The application checks if the host parameter is not '0.0.0.0' to restrict access, which is inadequate when the application is bound to a specific interface, allowing unauthorized…

access to endpoints such as '/restart_program', '/update_software', '/check_update', '/start_recording', and '/stop_recording'. This vulnerability can lead to denial of service, unauthorized disabling or overriding of recordings, and potentially other impacts if certain features are enabled in the configuration.

Mitigating Controls (NIST 800-53 r5) AI

Requires a tamperproof, always-invoked reference monitor that structurally blocks bypass via any alternate path.

Enforces authorization checks on every logical access path, eliminating unauthenticated alternate channels.

Mandates unique identification and authentication for all organizational users, covering the primary authentication requirement.

Controls all external and key internal interfaces, reducing the chance of unauthenticated alternate channels.
