Detailsinfo

A vulnerability, which was classified as critical, was found in Microsoft UFO 3.0.1-4-ge2626659. Affected is an unknown code block of the file logs/. The manipulation of the argument task_name with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

Microsoft UFO open-source framework for intelligent automation across devices and platforms. In 3.0.1-4-ge2626659, Microsoft UFO uses the user-controlled task_name value directly when constructing session log paths. An authenticated client can supply path traversal sequences in task_name and cause UFO to create log directories and log files outside the intended logs/ directory.
