Description

A blind Server-Side Request Forgery (SSRF) vulnerability was found in Moodle. This flaw exists due to insufficient validation of user-supplied input in LTI provider library. The library does not utilise Moodle's inbuilt cURL helper, which resulted in a blind SSRF risk. An attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems. This vulnerability allows a remote attacker to perform SSRF attacks.

• Fedoraproject Extra Packages For Enterprise Linux: 7.0
• Fedoraproject Fedora: 35, 36, 37
• Moodle: before 3.9.18; from 3.11.0 before 3.11.11; from 4.0.0 before 4.0.5 — fixed in 3.11.11, 3.9.18, 4.0.5

How to fix

Upgrade to a fixed version: Moodle 3.11.11, 3.9.18, 4.0.5. Check the vendor advisory for mitigations.
