CVSS v3.1 |
| The TitleIcon extension for MediaWiki is vulnerable to stored XSS through the #titleicon_unicode parser function. User input passed to this function is wrapped in an HtmlArmor object without sanitization and rendered directly into the page header, allowing attackers to inject arbitrary JavaScript.
This issue affects Mediawiki - TitleIcon extension: from 1.39.X before 1.39.13, from 1.42.X before 1.42.7, from 1.43.X before 1.43.2. |
| DataDump is a MediaWiki extension that provides dumps of wikis. Several interface messages are unescaped (more specifically, (datadump-table-column-queued), (datadump-table-column-in-progress), (datadump-table-column-completed), (datadump-table-column-failed)). If these messages are edited (which requires the (editinterface) right by default), anyone who can view Special:DataDump (which requires the (view-dump) right by default) can be XSSed. This vulnerability is fixed with 601688ee8e8808a23b102fa305b178f27cbd226d. |
| ImportDump is an extension for mediawiki designed to automate user import requests. Anyone who can edit the interface strings of a wiki (typically administrators and interface admins) can embed XSS payloads in the messages for dates, and thus XSS anyone who views Special:RequestImportQueue. This issue has been patched in commit `d054b95` and all users are advised to apply this commit to their branch. Users unable to upgrade may either Prevent access to Special:RequestImportQueue on all wikis, except for the global wiki; and If an interface administrator (or equivalent) level protection is available (which is not provided by default) on the global wiki, protect the affected messages up to that level. This causes the XSS to be virtually useless as users with those rights can already edit Javascript pages. Or Prevent access to Special:RequestImportQueue altogether. |
| CreateWiki is Miraheze's MediaWiki extension for requesting & creating wikis. It is possible for users to be considered as the requester of a specific wiki request if their local user ID on any wiki in a wiki farm matches the local ID of the requester at the wiki where the wiki request was made. This allows them to go to that request entry's on Special:RequestWikiQueue on the wiki where their local user ID matches and take any actions that the wiki requester is allowed to take from there.
Commit 02e0f298f8d35155c39aa74193cb7b867432c5b8 fixes the issue. Important note about the fix: This vulnerability has been fixed by disabling access to the REST API and special pages outside of the wiki configured as the "global wiki" in `$wgCreateWikiGlobalWiki` in a user's MediaWiki settings.
As a workaround, it is possible to disable the special pages outside of one's own global wiki by doing something similar to `miraheze/mw-config` commit e5664995fbb8644f9a80b450b4326194f20f9ddc that is adapted to one's own setup. As for the REST API, before the fix, there wasn't any REST endpoint that allowed one to make writes. Regardless, it is possible to also disable it outside of the global wiki by using `$wgCreateWikiDisableRESTAPI` and `$wgConf` in the configuration for one's own wiki farm.. |
| An issue was discovered in the PageTriage extension in MediaWiki before 1.35.14, 1.36.x through 1.39.x before 1.39.6, and 1.40.x before 1.40.2. XSS can occur via the rev-deleted-user, pagetriage-tags-quickfilter-label, pagetriage-triage, pagetriage-filter-date-range-format-placeholder, pagetriage-filter-date-range-to, pagetriage-filter-date-range-from, pagetriage-filter-date-range-heading, pagetriage-filter-set-button, or pagetriage-filter-reset-button message. |
| An issue was discovered in the CampaignEvents extension in MediaWiki before 1.35.14, 1.36.x through 1.39.x before 1.39.6, and 1.40.x before 1.40.2. The Special:EventDetails page allows XSS via the x-xss language setting for internationalization (i18n). |
| An issue was discovered in the CheckUser extension for MediaWiki through 1.42.1. It can expose suppressed information for log events. (The log_deleted attribute is not respected.) |
| An issue was discovered in the AbuseFilter extension for MediaWiki before 1.39.9, 1.40.x and 1.41.x before 1.41.3, and 1.42.x before 1.42.2. An API caller can match a filter condition against AbuseFilter logs even if the caller is not authorized to view the log details for the filter. |
| An issue was discovered in the CheckUser extension in MediaWiki before 1.35.14, 1.36.x through 1.39.x before 1.39.6, and 1.40.x before 1.40.2. XSS can occur via message definitions. e.g., in SpecialCheckUserLog. |
| An issue was discovered in the Phonos extension in MediaWiki before 1.40.2. PhonosButton.js allows i18n-based XSS via the phonos-purge-needed-error message. |
| An issue was discovered in the WatchAnalytics extension in MediaWiki before 1.40.2. XSS can occur via the Special:PageStatistics page parameter. |
| An issue was discovered in the Cargo extension in MediaWiki before 1.35.14, 1.36.x through 1.39.x before 1.39.6, and 1.40.x before 1.40.2. The Special:Drilldown page allows XSS via artist, album, and position parameters because of applied filter values in drilldown/CargoAppliedFilter.php. |
| A denial-of-service issue was discovered in MediaWiki 1.37.x before 1.37.2. Rendering of w/index.php?title=Special%3AWhatLinksHere&target=Property%3AP31&namespace=1&invert=1 can take more than thirty seconds. There is a DDoS risk. |
| api.php in MediaWiki before 1.27.4, 1.28.x before 1.28.3, and 1.29.x before 1.29.2 has a Reflected File Download vulnerability. |
| MediaWiki before 1.23.15, 1.26.x before 1.26.4, and 1.27.x before 1.27.1 does not generate head items in the context of a given title, which allows remote attackers to obtain sensitive information via a parse action to api.php. |
| MediaWiki before 1.18.5, and 1.19.x before 1.19.2 does not properly protect user block metadata, which allows remote administrators to read a user block reason via a reblock attempt. |
| MediaWiki before 1.23.15, 1.26.x before 1.26.4, and 1.27.x before 1.27.1 allows remote authenticated users with undelete permissions to bypass intended suppressrevision and deleterevision restrictions and remove the revision deletion status of arbitrary file revisions by using Special:Undelete. |
| MediaWiki 1.27.x before 1.27.1 might allow remote attackers to bypass intended session access restrictions by leveraging a call to the UserGetRights function after Session::getAllowedUserRights. |
| MediaWiki before 1.18.5, and 1.19.x before 1.19.2 allows remote attackers to bypass GlobalBlocking extension IP address blocking and create an account via unspecified vectors. |
| MediaWiki before 1.27.4, 1.28.x before 1.28.3, and 1.29.x before 1.29.2 has XSS when the $wgShowExceptionDetails setting is false and the browser sends non-standard URL escaping. |
