Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-4979 advisory.

Multiple security issues were found in MediaWiki, a website engine for collaborative work, which could result in cross-site scripting, denial of service and a bypass of restrictions in the Replace Text extension. For the oldstable distribution (buster), these problems have been fixed in version 1:1.31.16-1~deb10u1. For the stable distribution (bullseye), these problems have been fixed in version 1:1.35.4-1~deb11u1. We recommend that you upgrade your mediawiki packages. For the detailed security status of mediawiki please refer to its security tracker page at: https://security- tracker.debian.org/tracker/mediawiki

Tenable has extracted the preceding description block directly from the Debian security advisory.

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

Solution

Upgrade the mediawiki packages.

For the stable distribution (bullseye), these problems have been fixed in version 1
