Descriptions

A reflected cross-site scripting vulnerability exists in TCExam <= 14.8.4. The paths provided in the f, d, and dir parameters in tce_select_mediafile.php were not properly validated and could cause reflected XSS via the unsanitized output of the path supplied. An attacker could craft a malicious link which, if triggered by an administrator, could result in the attacker hijacking the victim's session or performing actions on their behalf.

Se presenta una vulnerabilidad de tipo cross-site scripting reflejado en TCExam versiones anteriores a 14.8.4 incluyéndola. Las rutas proporcionadas en los parámetros f, d, y dir en el archivo tce_select_mediafile.php no se han comprobado apropiadamente y podrían causar un ataque de tipo XSS reflejado por medio de la salida no saneada de la ruta suministrada. Un atacante podría diseñar un enlace malicioso que, si es habilitado por un administrador, podría resultar en el secuestro de la sesión de la víctima o llevar a cabo acciones en su nombre
