CVE-2024-4326

A vulnerability in parisneo/lollms-webui versions up to 9.3 allows remote attackers to execute arbitrary code. The vulnerability stems from insufficient protection of the /apply_settings and /execute_code endpoints. Attackers can bypass protections by setting the host to localhost, enabling code execution, and disabling code validation through the /apply_settings endpoint. Subsequently, arbitrary commands can be executed remotely via the /execute_code endpoint, exploiting the delay in settings enforcement. This issue was addressed in version 9.5.

Weakness

One or more system settings or configuration elements can be externally controlled by a user.

Potential Mitigations

• Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
• Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
