Publication date: 2026-08-20

Last updated on: 2026-08-20

Assigner: CERT.PL

Description
ATutor is vulnerable to Server-Side request forgery in import functionalities. An authenticated administrator can make the server request arbitrary internal HTTP endpoints, cloud metadata services, or local files via file:// if the PHP environment permits URL wrappers. 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.

Executive Summary

ATutor has a server-side request forgery (SSRF) vulnerability in its import functionalities. An authenticated administrator can trick the server into making HTTP requests to arbitrary internal endpoints, cloud metadata services, or local files via file:// if PHP's URL wrappers are enabled.

Detection Guidance

Since ATutor is no longer supported and lacks official patches, detection relies on identifying vulnerable versions or unusual server-side requests. Check if your system runs ATutor 2.2.4 or an untested version. Monitor server logs for unexpected internal HTTP requests or file:// access attempts from the application.

Impact Analysis

An attacker with admin access could exploit this to access internal systems, exfiltrate sensitive data, or interact with services not intended for external exposure. This could lead to data breaches or unauthorized actions on behalf of the server.

Compliance Impact

This vulnerability could lead to unauthorized data access or exfiltration, violating GDPR's data protection principles or HIPAA's security requirements for protected health information. Non-compliance may result in legal penalties or reputational damage.

Mitigation Strategies

Immediately upgrade to a supported alternative if possible. If using ATutor, restrict network access to the server, disable unused PHP URL wrappers, and block file:// requests. Implement strict input validation for import functionalities and monitor for suspicious outbound requests.
