Descriptions

A vulnerability in the management web interface of Cisco Expressway Series could allow an authenticated, remote attacker to perform a directory traversal attack against an affected device. The vulnerability is due to insufficient input validation on the web interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web interface. A successful exploit could allow the attacker to bypass security restrictions and access the web interface of a Cisco Unified Communications Manager associated with the affected device. Valid credentials would still be required to access the Cisco Unified Communications Manager interface.

Una vulnerabilidad en la interfaz web de gestión de Cisco Expressway Series podría permitir a un atacante remoto autenticado realizar un ataque de salto de directorio contra un dispositivo afectado. La vulnerabilidad se debe a una validación insuficiente de entrada en la interfaz web. Un atacante podría explotar esta vulnerabilidad enviando una petición HTTP a la interfaz web. Un exploit exitoso podría permitir al atacante eludir las restricciones de seguridad y acceder a la interfaz web de un Cisco Unified Communications Manager asociado con el dispositivo afectado. Se necesitarían credenciales válidas para acceder a la interfaz de Cisco Unified Communications Manager.

Cisco Expressway Gateway version 11.5.1 suffers from a directory traversal vulnerability.
