Descriptions

A vulnerability in the Tool for Auto-Registered Phones Support (TAPS) of Cisco Unified Communications Manager (UCM) and Cisco Unified Communications Manager Session Management Edition (SME) could allow an unauthenticated, remote attacker to conduct directory traversal attacks on an affected device. The vulnerability is due to insufficient validation of user-supplied input to the TAPS interface of the affected device. An attacker could exploit this vulnerability by sending a crafted request to the TAPS interface. A successful exploit could allow the attacker to read arbitrary files in the system.

Una vulnerabilidad en la Tool for Auto-Registered Phones Support (TAPS) de Cisco Unified Communications Manager (UCM) y Cisco Unified Communications Manager Session Management Edition (SME) podría permitir a un atacante remoto no autenticado conducir ataques de salto de directorio sobre un dispositivo afectado. La vulnerabilidad es debido a una comprobación insuficiente de la entrada suministrada por el usuario en la interfaz de TAPS del dispositivo afectado. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición diseñada hacia la interfaz de TAPS. Una explotación con éxito podría permitir a un atacante leer archivos arbitrarios en el sistema.
