Critical severity: a successful attack would have severe impact.

What to do

  1. Check which version of stitionai/devika you run against the affected versions below, and install the vendor's latest release.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

A path traversal vulnerability in the get-project-files functionality of stitionai/devika allows attackers to read arbitrary files from the filesystem and cause a Denial of Service (DoS). This issue is present in all versions of the application. The vulnerability arises due to insufficient path sanitization for the 'project-name' parameter, enabling attackers to specify paths that traverse the filesystem. By setting 'project-name' to the root directory, an attacker can cause the application to attempt to read the entire filesystem, leading to a DoS condition.

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.
