Descriptions

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
