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 MediaWiki 1.34.x before 1.34.4. On Special:Contributions, the NS filter uses unescaped messages as keys in the option key for an HTMLForm specifier. This is vulnerable to a mild XSS if one of those messages is changed to include raw HTML. Se detectó un problema en MediaWiki desde 1.34.x anteriores a 1.34.4. En Special:Contributions, el filtro NS usa mensajes sin escape como claves en la clave de opción para un especificador HTMLForm. • https://gerrit.wikimedia.org/g/mediawiki/core/+/ad4a3ba45fb955aa8c0eb3c83809b16b40a498b9/includes/specials/SpecialContributions.php#592 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 •

XSS exists in the MobileFrontend extension for MediaWiki before 1.34.4 because section.line is mishandled during regex section line replacement from PageGateway. Using crafted HTML, an attacker can elicit an XSS attack via jQuery's parseHTML method, which can cause image callbacks to fire even without the element being appended to the DOM. Una vulnerabilidad de tipo XSS se presenta en la extensión MobileFrontend para MediaWiki versiones anteriores a 1.34.4 porque section.line es manejada inapropiadamente durante el reemplazo de la línea de la sección de expresiones regulares desde PageGateway. Usando HTML diseñado, un atacante puede provocar un ataque XSS a través del método parseHTML de jQuery, que puede hacer que se activen las devoluciones de llamada de imagen incluso sin que el elemento se agregue al DOM • https://gerrit.wikimedia.org/r/q/I42e079bc875d17b336ab015f3678eaedc26e10ea https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RTTPZ7XMDS66I442OLLHXBDNP2LCBJU6 https://phabricator.wikimedia.org/T262213 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

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. En MediaWiki en versiones anteriores a la 1.31.8, 1.32.x y 1.33.x versiones anteriores a la 1.33.4, y 1.34.x en versiones anteriores a la 1.34.2, los wikis privados que se encuentran detrás de un servidor de almacenamiento en caché que utiliza la función de seguridad de autorización de imágenes img_auth.php pueden haber tenido sus archivos almacenados en caché públicamente, de modo que cualquier usuario no autorizado pueda verlos. Esto ocurre porque el control de la caché y las cabeceras de Vary se manejaron mal • https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/core/+/REL1_31/RELEASE-NOTES-1.31 https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/core/+/REL1_33/RELEASE-NOTES-1.33 https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/core/+/REL1_34/RELEASE-NOTES-1.34 https://lists.debian.org/debian-lts-announce/2020/12/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EEZIMLJMJS72SJXPYL736XMUAVCRQD2H https://lists.wikimedia.o •
