## Technical details

This is a path traversal (CWE-22) vulnerability in ATutor's error log viewer component. An attacker with administrative privileges can manipulate file path inputs to escape the intended logs directory and access arbitrary files on the system. The vulnerability requires administrative access, limiting the attack surface to trusted insiders or attackers who have already compromised an admin account. Successful exploitation allows reading sensitive files accessible by the web server process. ATutor is no longer actively supported, and no patches are available; only version 2.2.4 has been confirmed vulnerable.
