Cisco has released updates for some affected systems that addresses the Cisco TelePresence System default credentials vulnerability.
A vulnerability in Cisco TelePresence System could allow a remote attacker to access the web server via a user account that is created with default credentials.
The vulnerability is due to a default user account being created at installation time. An attacker could exploit this vulnerability by remotely accessing the web server and using the default account credentials. An exploit could allow the attacker to log in with the default credentials, which gives them full administrative rights to the system.
Cisco has confirmed the vulnerability in a security advisory and has released software updates for some affected products.
Cisco TelePresence System Software versions 1.8.1 through 1.10.1 are vulnerable while running on the following Cisco TelePresence System models:
Cisco TelePresence System Software versions 6.0.3 and prior are vulnerable while running on the following Cisco TelePresence models:
To exploit this vulnerability, an attacker would likely need access to trusted, internal networks in which the targeted device may reside. This access requirement could limit the likelihood of a successful exploit.
A remote attacker could exploit this vulnerability to gain unauthorized access to the affected device. Successful exploitation could allow the attacker to modify system configuration and settings that could result in a complete system compromise.
The vulnerability is due to insufficient security restrictions imposed by the affected software. As a result, the password recovery administrator account is enabled by default and accessible from the web server.
A remote attacker could exploit this vulnerability by logging in with the default credentials from the web server. Successful exploitation could allow the attacker to modify the system configuration and settings, which could be used to completely compromise the targeted system.
Administrators are advised to apply the appropriate updates.
Administrators are advised to contact the vendor regarding future updates and releases.
Administrators are advised to allow only trusted users to have network access.
Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.
An additional workaround is available for customers using TelePresence codecs registered with Cisco Unified Communications Manager (Unified CM). Details on implementing this workaround are described in the "Workarounds" section of the vendor advisory.
Administrators are advised to monitor affected systems.
Updates are available for Cisco TelePresence System Software Releases version 1.10.2 and above for the following products:
Updates for Cisco TelePresence System Software Releases version 6.x will be made available at a later date for the following products:
