Descriptions

The K2 component 2.8.0 for Joomla! has Incorrect Access Control with directory traversal, allowing an attacker to download arbitrary files, as demonstrated by a view=media&task=connector&cmd=file&target=l1_../configuration.php&download=1 request. The specific pathname ../configuration.php should be base64 encoded for a valid attack. NOTE: the vendor disputes this issue because only files under the media-manager path can be downloaded, and the documentation indicates that sensitive information does not belong there. Nonetheless, 2.8.1 has additional blocking of .php downloads

** EN DISPUTA ** El componente K2, versión 2.8.0, para Joomla! tiene control de acceso incorrecto con salto de directorio, permitiendo a un atacante descargar archivos arbitrarios, como lo demuestra una solicitud view=media&task=connector&cmd=file&target=l1_../configuration.php&download=1. La ruta específica ../configuration.php debería estar codificada en base64 para un ataque válido. NOTA: el proveedor no está de acuerdo con este punto porque sólo se pueden descargar los archivos que se encuentran en la ruta del administrador de medios, y la documentación indica que la información confidencial no pertenece a ese lugar. No obstante, la versión 2.8.1 tiene un bloqueo adicional de las descargas de .php.

Joomla! K2 component version 2.8.0 suffers from an arbitrary file download vulnerability.
