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.
AnalysisAI
Path traversal write in Microsoft UFO (build 3.0.1-4-ge2626659) lets an authenticated client smuggle directory-traversal sequences (e.g. ../) inside the user-controlled task_name value, which UFO concatenates directly into session log paths, causing it to create directories and write log files anywhere the process can reach outside the intended logs/ directory. …

Within 24 hours: Inventory all Microsoft UFO instances running version 3.0.1-4-ge2626659 or earlier; review recent UFO audit logs for suspicious task_name values containing '../' or path traversal patterns. Within 7 days: Restrict UFO network access and user access to only essential administrative accounts; implement task_name input validation to reject directory traversal sequences; reduce UFO process file system permissions to minimum required. …
