AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in the Microsoft UFO open-source framework for intelligent automation. In version 3.0.1-4-ge2626659, the software uses a user-controlled value called task_name directly when creating session log paths. Because an authenticated client can supply path traversal sequences in task_name, it can cause the system to create log directories and files outside the intended logs/ directory.
How can this vulnerability impact me? :
The vulnerability allows an authenticated user to perform path traversal attacks by manipulating the task_name value. This can lead to the creation of log files and directories outside the designated logs/ directory, potentially overwriting or creating files in unauthorized locations. The impact includes high integrity and availability risks, as indicated by the CVSS score, meaning attackers could alter or disrupt log files and related system operations.
