Cisco Unified Communications Manager Arbitrary File Read Vulnerability

A vulnerability in the bulk administration interface of Cisco Unified Communications Manager (UCM) could allow an authenticated, remote attacker to read arbitrary files from the underlying file system.

The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by providing crafted input at a specific prompt in the bulk administration interface. An exploit could allow the attacker to read arbitrary files from the underlying operating system.

Cisco has confirmed the vulnerability in a security notice; however, software updates are not available.

To exploit this vulnerability, an attacker must authenticate to the targeted device. This access requirement decreases the likelihood of a successful exploit.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
