-
A vulnerability in the administrative web interface of Cisco Unified Communications Manager could allow an authenticated, remote attacker to obtain the contents of arbitrary files on an affected device.
The vulnerability is due to a failure to properly sanitize user-supplied input passed to a specific function. An attacker could exploit this vulnerability by supplying a series of directory traversal characters, allowing the attacker to designate a file outside the restricted directory to be returned. An exploit could allow the attacker to obtain the contents of any file that is readable by the Apache Tomcat service account.
Cisco has confirmed the vulnerability in a security notice and released software updates.
To exploit this vulnerability, an attacker must be able to authenticate to a 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.
