CVE-2013-10051

A remote PHP code execution vulnerability exists in InstantCMS version 1.6 and earlier due to unsafe use of eval() within the search view handler. Specifically, user-supplied input passed via the look parameter is concatenated into a PHP expression and executed without proper sanitation. A remote attacker can exploit this flaw by sending a crafted HTTP GET request with a base64-encoded payload in the Cmd header, resulting in arbitrary PHP code execution within the context of the web server.

Summary		(es) Existe una vulnerabilidad de ejecución remota de código PHP en InstantCMS versión 1.6 y anteriores debido al uso inseguro de eval() en el controlador de la vista de búsqueda. En concreto, la entrada proporcionada por el usuario mediante el parámetro look se concatena en una expresión PHP y se ejecuta sin la debida corrección. Un atacante remoto puede explotar esta vulnerabilidad enviando una solicitud HTTP GET manipulada con un payload codificado en base64 en la cabecera Cmd, lo que provoca la ejecución de código PHP arbitrario en el contexto del servidor web.
