Synopsis
Moodle 3.9.x < 3.9.10 Multiple VulnerabilitiesDescription
The version of Moodle installed on the remote host is 3.9.x prior to 3.9.10, 3.10.x prior to 3.10.7 or 3.11.x prior to 3.11.3. It is, therefore, affected by multiple vulnerabilities:- A session hijack vulnerability was identified in the Shibboleth authentication plugin, when enabled. (CVE-2021-40691)
- An Insecure Direct Object Reference (IDOR) allowing teachers to download other courses users. (CVE-2021-40692)
- An authentication bypass vulnerability was identified in the external database authentication functionality due to a type juggling vulnerability. (CVE-2021-40693)
- An arbitrary file read due to an insufficient escaping of the LaTeX preamble allowing site administrators to read files available to the HTTP Server system account. (CVE-2021-40694)
- An information disclosure allowing students to see their quiz grade through the quiz web service before its release. (CVE-2021-40695)
Note that the scanner has not attempted to exploit this issue but has instead relied only on application's self-reported version number.
Solution
Upgrade to version 3.9.10 or later.See Also
