Detailsinfo

A vulnerability classified as critical has been found in Moodle (Learning Management Software) (the affected version is unknown). This affects an unknown code of the component LTI Provider Library. The manipulation with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was disclosed 11/26/2022. It is possible to read the advisory at git.moodle.org. This vulnerability is uniquely identified as CVE-2022-45152 since 11/11/2022. The technical details are unknown and an exploit is not publicly available.
