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.
AnalysisAI
Server-side request forgery in ATutor's import functionalities allows an authenticated administrator to coerce the server into issuing HTTP requests to arbitrary internal endpoints, cloud metadata services such as AWS IMDSv1, or local filesystem paths via the file:// URI scheme where PHP URL wrappers are enabled. Only version 2.2.4 has been confirmed vulnerable by CERT.pl researchers; the product is end-of-life with no planned fix. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid ATutor administrator account - the CVSS 4.0 PR:H metric confirms high privilege is necessary and unauthenticated exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.1 reflects the high privilege requirement (PR:H) that constrains realistic attack surface to compromised or malicious administrators. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch exists and none is anticipated, as ATutor is end-of-life and no longer actively supported. … Detailed patch versions, workarounds, and compensating controls in full report. |
