Debian DLA-3117-1 : mediawiki – LTS security update
Discription

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3117 advisory.

– An issue was discovered in MediaWiki before 1.35.6, 1.36.x before 1.36.4, and 1.37.x before 1.37.2. Users with the editinterface permission can trigger infinite recursion, because a bare local interwiki is mishandled for the mainpage message. (CVE-2022-28201)

– An XSS issue was discovered in MediaWiki before 1.35.6, 1.36.x before 1.36.4, and 1.37.x before 1.37.2.
The widthheight, widthheightpage, and nbytes properties of messages are not escaped when used in galleries or Special:RevisionDelete. (CVE-2022-28202)

– A denial-of-service issue was discovered in MediaWiki before 1.35.6, 1.36.x before 1.36.4, and 1.37.x before 1.37.2. When many files exist, requesting Special:NewFiles with actor as a condition can result in a very long running query. (CVE-2022-28203)

– An issue was discovered in MediaWiki before 1.35.7, 1.36.x and 1.37.x before 1.37.3, and 1.38.x before 1.38.1. XSS can occur in configurations that allow a JavaScript payload in a username. After account creation, when it sets the page title to Welcome followed by the username, the username is not escaped:
SpecialCreateAccount::successfulAction() calls ::showSuccessPage() with a message as second parameter, and OutputPage::setPageTitle() uses text(). (CVE-2022-34911)

– An issue was discovered in MediaWiki before 1.37.3 and 1.38.x before 1.38.1. The contributions-title, used on Special:Contributions, is used as page title without escaping. Hence, in a non-default configuration where a username contains HTML entities, it won’t be escaped. (CVE-2022-34912)

– Mediawiki reports: (T292763. CVE-2021-44854) REST API incorrectly publicly caches autocomplete search results from private wikis. (T271037, CVE-2021-44856) Title blocked in AbuseFilter can be created via Special:ChangeContentModel. (T297322, CVE-2021-44857) Unauthorized users can use action=mcrundo to replace the content of arbitrary pages. (T297322, CVE-2021-44858) Unauthorized users can view contents of private wikis using various actions. (T297574, CVE-2021-45038) Unauthorized users can access private wiki contents using rollback action (T293589, CVE-2021-44855) Blind Stored XSS in VisualEditor media dialog. (T294686) Special:Nuke doesn’t actually delete pages. (CVE-2021-44856)

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