Cisco Unified Communications Manager DNA Path Traversal Vulnerability

A vulnerability in the /dna/viewfilecontents.do URL of the Cisco Unified Communications Manager Dialed Number Analyzer (DNA) could allow an authenticated, remote attacker to view files from specific locations on the filesystem.

The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by submitting crafted URL
requests to a vulnerable device.

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

To exploit this vulnerability, an attacker must authenticate to a targeted system. This access requirement may reduce 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.
