According to its self-reported version number, the instance of MediaWiki hosted on the remote web server is prior to 1.39.12, 1.42.x prior to 1.42.6 or 1.43.x prior to 1.43.1. It is, therefore, affected by a number of vulnerabilities as follows.

- Improper restrictions on the file revert action. (CVE-2025-32696)

- PermissionManager fails to differentiate between cascading protection sources, allowing an unauthorized user to edit protected pages. (CVE-2025-32697)

- LogPager restriction enforcement functions do not properly restrict access to suppressed log entries. (CVE-2025-32698)

- Potential JavaScript injection via Unicode normalization enabling XSS attacks. (CVE-2025-32699)

- An i18n XSS vulnerability in HTMLMultiSelectField with sections. (CVE-2025-3469)

- AbuseFilter log interfaces expose private/hidden filters when they should be restricted. (CVE-2025-32700)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - Improper Preservation of Permissions vulnerability in Wikimedia Foundation MediaWiki. This vulnerability     is associated with program files includes/editpage/IntroMessageBuilder.Php,     includes/Permissions/PermissionManager.Php, includes/Permissions/RestrictionStore.Php. This issue affects     MediaWiki: before 1.42.6, 1.43.1. (CVE-2025-32697)

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

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5901 advisory.
