Path Traversal: '.../...//'

CVE-2024-21575

High
9.2/10

Summary

ComfyUI-Impact-Pack is vulnerable to Path Traversal. The issue stems from missing validation of the `image.filename` field in a POST request sent to the `/upload/temp` endpoint added by the extension to the server. This results in writing arbitrary files to the file system which may, under some conditions, result in remote code execution (RCE).

CWE-35 - Path Traversal: '.../...//'

The software uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '.../...//' (doubled triple dot slash) sequences that can resolve to a location that is outside of that directory.
