In Moodle 2.x and 3.x, searching of arbitrary blogs is possible because a capability check is missing.

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

  - In Moodle 2.x and 3.x, searching of arbitrary blogs is possible because a capability check is missing.
    (CVE-2017-7490)

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

The remote web server hosts Moodle, an open-source course management system. Versions of Moodle 3.2.x prior to 3.2.3 are affected by multiple vulnerabilities :

 - Unspecified flaws exist that may allow an attacker to have an unspecified impact. No further details have been provided by the vendor.
 - A flaw exists that may allow an authenticated remote attacker to edit the external blog links of other users. This may allow the attacker to take ownership of arbitrary blogs.
 - A flaw exists that is due to a lack of capability checks. This may allow an authenticated remote attacker to search arbitrary blogs.
 - A flaw exists as HTTP requests to the 'my/index.php' script do not require multiple steps, explicit confirmation, or a unique token when performing certain sensitive actions. By tricking a user into following a specially crafted link, a context-dependent attacker can perform a Cross-Site Request Forgery (CSRF / XSRF) attack causing the victim to change the number of courses displayed in the course overview block.
