Moodle 3.9.x < 3.9.18 Multiple Vulnerabilities

The version of Moodle installed on the remote host is 3.9.x prior to 3.9.18, 3.11.x prior to 3.11.11 or 4.0.x prior to 4.0.5. It is, therefore, affected by multiple vulnerabilities:

• An information disclosure due to a user CSRF token being unnecessarily included in the URL during the redirection to a course which has been just restored. (CVE-2022-45149)

• A Cross-Site Scripting (XSS) vulnerability due to the lack of sanitization of the return URL in the policy tool. (CVE-2022-45150)

• A stored Cross-Site Scripting (XSS) vulnerability due to the lack of sanitization of the ‘social’ user profile field type. (CVE-2022-45151)

• A blind Server-Side Request Forgery (SSRF) vulnerability due to the LTI provider library not using Moodle inbuilt cURL helper. (CVE-2022-45152)

Note that the scanner has not attempted to exploit this issue but has instead relied only on application’s self-reported version number.
