mintplex-labs/anything-llm: Improper Access Control

Published Updated By the CyberSecBulletin desk

CVE-2024-0551 is a high-severity improper access control vulnerability in mintplex-labs/anything-llm from Mintplex-labs, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 1.0.0 as the first without the flaw, so updating mintplex-labs/anything-llm to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.56% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

Enable exports of the database and associated exported information of the system via the default user role. The attacked would have to have been granted access to the system prior to the attack. It is worth noting that the deterministic nature of the export name is lower risk as the UI for exporting would start the download at the same time, which once downloaded - deletes the export from the system. The endpoint for exporting should simply be patched to a higher privilege level.

The underlying weakness: Improper Access Control

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

How developers prevent this class of flaw

  • Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
  • 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.
