Source: CVE Database V5
Vendor/Project: Cisco
Product: Cisco Unity Connection

Description

A vulnerability in the web-based management interface of Cisco Unity Connection could allow an authenticated, remote attacker to execute arbitrary code on an affected device. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by submitting a crafted API request. A successful exploit could allow the attacker to execute arbitrary code as root, possibly resulting in the complete compromise of a targeted device. To exploit this vulnerability, the attacker must have valid user credentials on the affected device.

Technical Analysis

This vulnerability in Cisco Unity Connection arises from improper validation of user input in the web management interface, enabling an authenticated attacker to perform path traversal attacks using crafted API requests. Exploitation results in arbitrary code execution with root privileges, potentially compromising the entire device. The vulnerability requires valid user credentials and affects a wide range of Cisco Unity Connection versions. The CVSS 3.1 base score is 8.8, indicating high severity with network attack vector, low attack complexity, required privileges, no user interaction, and high impact on confidentiality, integrity, and availability.

Potential Impact

An attacker with valid credentials can execute arbitrary code as root on the affected Cisco Unity Connection device, potentially leading to full system compromise. This includes unauthorized access, modification, or disruption of system operations. The high CVSS score reflects the critical nature of the impact on confidentiality, integrity, and availability.

Mitigation Recommendations

Patch status is not yet confirmed — check the Cisco vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the management interface to trusted users only and monitor for suspicious activity. Since exploitation requires valid credentials, enforcing strong authentication and credential management is recommended.
