mintplex-labs/anything-llm: Path Traversal: '..filename'
CVE-2024-5211 is a high-severity path traversal: '..filename' vulnerability in mintplex-labs/anything-llm from Mintplex-labs, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, 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 1.05% chance of exploitation within 30 days, higher than 65% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update mintplex-labs/anything-llm to 1.0.0 or a later version.
- Update anythingllm to 1.0.0 or a later version.

Official description
A path traversal vulnerability in mintplex-labs/anything-llm allowed a manager to bypass the `normalizePath()` function, intended to defend against path traversal attacks. This vulnerability enables the manager to read, delete, or overwrite the 'anythingllm.db' database file and other files stored in the 'storage' directory, such as internal communication keys and .env secrets. Exploitation of this vulnerability could lead to application compromise, denial of service (DoS) attacks, and unauthorized admin account takeover. The issue stems from improper validation of user-supplied input in the process of setting a custom logo for the app, which can be manipulated to achieve arbitrary file read, deletion, or overwrite, and to execute a DoS attack by deleting critical files required for the application's operation.

The underlying weakness: Path Traversal: '..filename'
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '..filename' (leading backslash dot dot) sequences that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
