mintplex-labs/anything-llm: Path Traversal: '..filename'

CVE-2024-8248 is a high-severity path traversal: '..filename' vulnerability in mintplex-labs/anything-llm from Mintplex-labs, with a CVSS 3.0 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 1.2.2 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 0.89% chance of exploitation within 30 days, higher than 60% of scored CVEs.

Official description

A vulnerability in the normalizePath function in mintplex-labs/anything-llm version git 296f041 allows for path traversal, leading to arbitrary file read and write in the storage directory. This can result in privilege escalation from manager to admin. The issue is fixed in version 1.2.2.

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.
