The remote Fedora 36 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-d9c13996b2 advisory.
Insufficient validation of profile field availability condition resulted in an SQL injection risk (by default only available to teachers and managers). (CVE-2023-28329)
Insufficient sanitizing in backup resulted in an arbitrary file read risk. The capability to access this feature is only available to teachers, managers and admins by default. (CVE-2023-28330)
Content output by the database auto-linking filter required additional sanitizing to prevent an XSS risk.
(CVE-2023-28331)
If the algebra filter was enabled but not functional (eg the necessary binaries were missing from the server), it presented an XSS risk. (CVE-2023-28332)
The Mustache pix helper contained a potential Mustache injection risk if combined with user input (note:
This did not appear to be implemented/exploitable anywhere in the core Moodle LMS). (CVE-2023-28333)
Insufficient filtering of grade report history made it possible for teachers to access the names of users they could not otherwise access. (CVE-2023-28336)
The course participation report required additional checks to prevent roles being displayed which the user did not have access to view. (CVE-2023-1402)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
