Cisco TC Software Empty Password Validation Vulnerability

A vulnerability in the web portal of Cisco TelePresence endpoints running TC software could allow an unauthenticated, remote attacker to log in with any password.

The vulnerability is due to a failure of the Cisco TelePresence endpoints to require an exact match for the password before the user has configured a password for the first time. An attacker could exploit this vulnerability by logging in with any password.

Cisco has confirmed the vulnerability in a security notice and has released software updates.

To exploit this vulnerability, an attacker may require access to trusted, internal networks to attempt to log in to the affected software. In addition, the attacker must have knowledge of a username for a user who has not yet configured a password. These requirements could limit 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.
