Summary

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.

Risk Assessment

An attacker with instructor privileges can achieve remote code execution on the server, potentially leading to full server compromise and breach of confidentiality, integrity, and availability of data.

Recommendation

It is recommended to stop using ATutor as it is no longer supported and has no fixes. If necessary, restrict access to the system and monitor it for suspicious activities.
