Cisco Unity Connection contains a vulnerability that could allow an authenticated, remote attacker to conduct directory traversal attacks. Updates are available.
To exploit this vulnerability, an attacker must authenticate to place arbitrary files in certain locations on an affected device. This access requirement decreases the likelihood of a successful exploit.
If the VMWS recognizes a file other than an audio file, the service would remove the file, which shortens the window of an affected device accessing an arbitrary file uploaded by an attacker.
Cisco indicates through the CVSS score that functional exploit code exists.
Customers are advised to consult Cisco bug ID CSCuj22948 or the most complete list of affected product versions.
