CVE-2008-0460 2 Mediawiki, Microsoft 3 Mediawiki, Mediawiki Botquery Ext, Internet Explorer 2021-07-23 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in api.php in (1) MediaWiki 1.11 through 1.11.0rc1, 1.10 through 1.10.2, 1.9 through 1.9.4, and 1.8; and (2) the BotQuery extension for MediaWiki 1.7 and earlier; when Internet Explorer is used, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
CVE-2011-1578 2 Mediawiki, Microsoft 2 Mediawiki, Internet Explorer 2021-07-23 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in MediaWiki before 1.16.3, when Internet Explorer 6 or earlier is used, allows remote attackers to inject arbitrary web script or HTML via an uploaded file accessed with a dangerous extension such as .html at the end of the query string, in conjunction with a modified URI path that has a %2E sequence in place of the . (dot) character.
CVE-2020-35623 1 Mediawiki 1 Mediawiki 2021-07-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in the CasAuth extension for MediaWiki through 1.35.1. Due to improper username validation, it allowed user impersonation with trivial manipulations of certain characters within a given username. An ordinary user may be able to login as a "bureaucrat user" who has a similar username, as demonstrated by usernames that differ only in (1) bidirectional override symbols or (2) blank space.
CVE-2020-10534 1 Mediawiki 1 Mediawiki 2021-07-21 7.5 HIGH 9.8 CRITICAL
In the GlobalBlocking extension before 2020-03-10 for MediaWiki through 1.34.0, an issue related to IP range evaluation resulted in blocked users re-gaining escalated privileges. This is related to the case in which an IP address is contained in two ranges, one of which is locally disabled.
CVE-2020-10960 1 Mediawiki 1 Mediawiki 2021-07-21 5.0 MEDIUM 5.3 MEDIUM
In MediaWiki before 1.34.1, users can add various Cascading Style Sheets (CSS) classes (which can affect what content is shown or hidden in the user interface) to arbitrary DOM nodes via HTML content within a MediaWiki page. This occurs because jquery.makeCollapsible allows applying an event handler to any Cascading Style Sheets (CSS) selector. There is no known way to exploit this for cross-site scripting (XSS).
CVE-2020-15005 3 Debian, Fedoraproject, Mediawiki 3 Debian Linux, Fedora, Mediawiki 2021-07-21 2.6 LOW 3.1 LOW
In MediaWiki before 1.31.8, 1.32.x and 1.33.x before 1.33.4, and 1.34.x before 1.34.2, private wikis behind a caching server using the img_auth.php image authorization security feature may have had their files cached publicly, so any unauthorized user could view them. This occurs because Cache-Control and Vary headers were mishandled.
CVE-2020-35625 1 Mediawiki 1 Mediawiki 2021-07-21 6.5 MEDIUM 8.8 HIGH
An issue was discovered in the Widgets extension for MediaWiki through 1.35.1. Any user with the ability to edit pages within the Widgets namespace could call any static function within any class (defined within PHP or MediaWiki) via a crafted HTML comment, related to a Smarty template. For example, a person in the Widget Editors group could use \MediaWiki\Shell\Shell::command within a comment.
CVE-2020-29005 1 Mediawiki 1 Mediawiki 2021-07-21 5.0 MEDIUM 7.5 HIGH
The API in the Push extension for MediaWiki through 1.35 used cleartext for ApiPush credentials, allowing for potential information disclosure.
CVE-2020-12051 1 Mediawiki 1 Mediawiki 2021-07-21 5.0 MEDIUM 7.5 HIGH
The CentralAuth extension through REL1_34 for MediaWiki allows remote attackers to obtain sensitive hidden account information via an api.php?action=query&meta=globaluserinfo&guiuser= request. In other words, the information can be retrieved via the action API even though access would be denied when simply visiting wiki/Special:CentralAuth in a web browser.
CVE-2021-36125 1 Mediawiki 1 Mediawiki 2021-07-07 5.0 MEDIUM 7.5 HIGH
An issue was discovered in the CentralAuth extension in MediaWiki through 1.36. The Special:GlobalRenameRequest page is vulnerable to infinite loops and denial of service attacks when a user's current username is beyond an arbitrary maximum configuration value (MaxNameChars).
CVE-2021-36126 1 Mediawiki 1 Mediawiki 2021-07-07 7.5 HIGH 9.8 CRITICAL
An issue was discovered in the AbuseFilter extension in MediaWiki through 1.36. If the MediaWiki:Abusefilter-blocker message is invalid within the content language, the filter user falls back to the English version, but that English version could also be invalid on a wiki. This would result in a fatal error, and potentially fail to block or restrict a potentially nefarious user.
