Name of the Vulnerable Software and Affected Versions Jiangnan Online Judge (aka jnoj) version 0.8.0

Description The issue allows for Directory Traversal, which can be exploited for file deletion. This is achieved through a specific substring in the "web/polygon/problem/deletefile" API endpoint, specifically by manipulating the id and name parameters with a ../ substring.

Recommendations For version 0.8.0, as a temporary workaround, consider restricting access to the "web/polygon/problem/deletefile" API endpoint until a patch is available. Avoid using the name parameter with ../ substring in the affected endpoint to minimize the risk of exploitation.
