Descriptions

includes/libs/IEUrlExtension.php in the MediaWiki API in MediaWiki 1.19.x before 1.19.8, 1.20.x before 1.20.7, and 1.21.x before 1.21.2 does not properly detect extensions when there are an even number of "." (period) characters in a string, which allows remote attackers to conduct cross-site scripting (XSS) attacks via the siprop parameter in a query action to wiki/api.php.

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.
