Synopsis
Moodle 3.9.x < 3.9.5 Multiple VulnerabilitiesDescription
The version of Moodle installed on the remote host is 3.5.x prior to 3.5.17, 3.8.x prior to 3.8.8, 3.9.x prior to 3.9.5 or 3.10.x prior to 3.10.2.

- A stored Cross-Site Scripting (XSS) and blind Server-Side Request Forgery (SSRF) vulnerabilities due to the lack of sanitization of text-based feedback answers. (CVE-2021-20280)
- An information disclosure exposing other users full names via the online users block. (CVE-2021-20281)
- A bypass in the email verification process when confirming an account registration. (CVE-2021-20282)
- An Insecure Direct Object Reference (IDOR) allowing an user to request other users enrolled courses through the web service. (CVE-2021-20283)
- A vulnerable jQuery component. (CVE-2020-11022, CVE-2020-11023)
Note that the scanner has not attempted to exploit this issue but has instead relied only on application's self-reported version number.
