ATutor is susceptible to a Path Traversal vulnerability in its ZIP extraction feature, allowing attackers with instructor privileges to upload and extract malicious ZIP files. This exploitation can lead to remote code execution by placing executable files in the web root, compromising the server with web server privileges. Organizations still using version 2.2.4 or similar unsupported versions should prioritize immediate remediation to mitigate the risk of exploitation.

Original NVD Description

ATutor is vulnerable to a Path Traversal vulnerability in ZIP extraction functionality. An attacker with instructor privileges can upload and extract a specially crafted ZIP archive, causing files to be written outside the intended extraction directory. This allows an attacker to place a server-executable .phtml file in the web root and achieve remote code execution with web server privileges on the underlying server. Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.
