Descriptions

A vulnerability in the web interface of Cisco Network Analysis Module Software could allow an unauthenticated, remote attacker to delete arbitrary files from an affected system, aka Directory Traversal. The vulnerability exists because the affected software does not perform proper input validation of HTTP requests that it receives and the software does not apply role-based access controls (RBACs) to requested HTTP URLs. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected software. A successful exploit could allow the attacker to delete arbitrary files from the affected system. Cisco Bug IDs: CSCvf41365.

Una vulnerabilidad en la interfaz web del software Cisco Network Analysis Module podría permitir que un atacante remoto no autenticado elimine archivos arbitrarios de un sistema afectado. Esto también se conoce como salto de directorio. Esta vulnerabilidad existe porque el software afectado no realiza una correcta validación de entradas de las peticiones HTTP que recibe y el software no aplica controles de acceso basados en roles (RBAC) a URL HTTP solicitadas. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición HTTP manipulada al software afectado. Un exploit con éxito podría permitir que el atacante elimine archivos arbitrarios del sistema afectado. Cisco Bug IDs: CSCvf41365.

This vulnerability allows remote attackers to delete arbitrary files on vulnerable installations of Cisco Prime Network Analysis Module. Authentication is not required to exploit this vulnerability.
The specific flaw exists within graph.php. When parsing the sfile parameter, the script does not properly validate a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to delete any files accessible to the web service.
