An issue was discovered in MediaWiki before 1.31.10 and 1.32.x through 1.34.x before 1.34.4. The non-jqueryMsg version of mw.message().parse() doesn't escape HTML. This affects both message contents (which are generally safe) and the parameters (which can be based on user input). (When jqueryMsg is loaded, it correctly accepts only whitelisted tags in message contents, and escapes all parameters. Situations with an unloaded jqueryMsg are rare in practice, but can for example occur for Special:SpecialPages on a wiki with no extensions installed.) • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RTTPZ7XMDS66I442OLLHXBDNP2LCBJU6 https://lists.wikimedia.org/pipermail/mediawiki-announce https://lists.wikimedia.org/pipermail/mediawiki-l/2020-September/048480.html https://lists.wikimedia.org/pipermail/mediawiki-l/2020-September/048488.html • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

In MediaWiki before 1.31.10 and 1.32.x through 1.34.x before 1.34.4, XSS related to jQuery can occur. The attacker creates a message with [javascript:payload xss] and turns it into a jQuery object with mw.message().parse(). The expected result is that the jQuery object does not contain an <a> tag (or it does not have a href attribute, or it's empty, etc.). The actual result is that the object contains an <a href ="javascript... that executes when clicked. En MediaWiki versiones anteriores a 1.31.10 y desde 1.32.x hasta 1.34.x anteriores a 1.34.4, puede ocurrir un ataque de tipo XSS relacionado con jQuery. • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RTTPZ7XMDS66I442OLLHXBDNP2LCBJU6 https://lists.wikimedia.org/pipermail/mediawiki-l/2020-September/048480.html https://lists.wikimedia.org/pipermail/mediawiki-l/2020-September/048488.html https://www.mediawiki.org/wiki/ResourceLoader/Core_modules#mediawiki.jqueryMsg • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

An issue was discovered in MediaWiki 1.32.x through 1.34.x before 1.34.4. LogEventList::getFiltersDesc is insecurely using message text to build options names for an HTML multi-select field. The relevant code should use escaped() instead of text(). Se detectó un problema en MediaWiki desde 1.32.x hasta 1.34.x anteriores a 1.34.4. La función LogEventList::getFiltersDesc usa de forma no segura el texto del mensaje para crear nombres de opciones para un campo de selección múltiple HTML. • https://gerrit.wikimedia.org/g/mediawiki/core/+/ec76e14be658187544f07c1a249a047e1a75eaf8/includes/logging/LogEventsList.php#214 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RTTPZ7XMDS66I442OLLHXBDNP2LCBJU6 https://lists.wikimedia.org/pipermail/mediawiki-l/2020-September/048480.html https://lists.wikimedia.org/pipermail/mediawiki-l/2020-September/048488.html • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

An issue was discovered in the FileImporter extension for MediaWiki before 1.34.4. An attacker can import a file even when the target page is protected against "page creation" and the attacker should not be able to create it. This occurs because of a mishandled distinction between an upload restriction and a create restriction. An attacker cannot leverage this to overwrite anything, but can leverage this to force a wiki to have a page with a disallowed title. Se detectó un problema en la extensión FileImporter para MediaWiki versiones anteriores a 1.34.4. • https://commons.wikimedia.org/w/index.php?oldid=454609892#File:Wiki.png https://gerrit.wikimedia.org/r/q/Ib852a96afc4dca10516d0510e69c10f9892b351b https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RTTPZ7XMDS66I442OLLHXBDNP2LCBJU6 https://phabricator.wikimedia.org/T262628 • CWE-863: Incorrect Authorization •
