CVE-2013-4303

Estado: ModificadaMedia (6.1)—

El archivo includes/libs/IEUrlExtension.php en la API MediaWiki en MediaWiki versiones 1.19.x anteriores a 1.19.8, versiones 1.20.x anteriores a 1.20.7 y versiones 1.21.x anteriores a 1.21.2 no detecta apropiadamente las extensiones cuando existe un número par de caracteres "." (punto) en una cadena, lo que permite a atacantes remotos realizar ataques de tipo cross-site scripting (XSS) por medio del parámetro siprop en una acción query en el archivo wiki/api.php.
