The vulnerability was found Moodle which exists due to insufficient sanitization of user-supplied data in blog search. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website. This flaw allows a remote attacker to perform cross-site scripting (XSS) attacks.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The vulnerability was found Moodle which exists due to insufficient sanitization of user-supplied data in     blog search. A remote attacker can trick the victim to follow a specially crafted link and execute     arbitrary HTML and script code in user's browser in context of vulnerable website. This flaw allows a     remote attacker to perform cross-site scripting (XSS) attacks. (CVE-2023-23922)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The vulnerability was found Moodle which exists due to insufficient sanitization of user-supplied data in
    blog search. A remote attacker can trick the victim to follow a specially crafted link and execute
    arbitrary HTML and script code in user's browser in context of vulnerable website. This flaw allows a
    remote attacker to perform cross-site scripting (XSS) attacks. (CVE-2023-23922)

The version of Moodle installed on the remote host is 3.9.x prior to 3.9.19, 3.11.x prior to 3.11.12, 4.0.x prior to 4.0.6 or 4.1.x prior to 4.1.1. It is, therefore, affected by multiple vulnerabilities:

 - A Cross-Site Scripting (XSS) vulnerability due to the lack of sanitization of some returnurl parameters. (CVE-2023-23921)

 - A Cross-Site Scripting (XSS) vulnerability due to the lack of sanitization in the blog search functionnality. (CVE-2023-23922)

 - An Insecure Direct Object Reference (IDOR) vulnerability allowing users to set the preferred start page of any other user. (CVE-2023-23923)

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