What is CVE-2024-3283?

CVE-2024-3283 is a high-severity vulnerability in Mintplexlabs Anythingllm, published on 10 Apr 2024. An attacker needs administrator access to exploit it, with no action from the victim.

Official description

A vulnerability in mintplex-labs/anything-llm allows users with manager roles to escalate their privileges to admin roles through a mass assignment issue. The '/admin/system-preferences' API endpoint improperly authorizes manager-level users to modify the 'multi_user_mode' system variable, enabling them to access the '/api/system/enable-multi-user' endpoint and create a new admin user. This issue results from the endpoint accepting a full JSON object in the request body without proper validation of modifiable fields, leading to unauthorized modification of system settings and subsequent privilege escalation.

Weakness: CWE-915
