Cisco TelePresence APIs that are hosted on Cisco TelePresence endpoint devices contain a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code. Updates are available.
Cisco TelePresence application programming interfaces (APIs) that are hosted on Cisco TelePresence endpoint devices contain a vulnerability related to Cisco TelePresence Immersive Endpoint System that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted device.
The vulnerability is due to improper processing of malformed requests by the affected software. An unauthenticated, remote attacker on an adjacent network could exploit this vulnerability by sending malicious requests to the device. If successful, the attacker could execute arbitrary commands on the device with elevated privileges, possibly resulting in a complete compromise.
Cisco has confirmed the vulnerability in a security advisory and released software updates.
Cisco TelePresence endpoint devices that are running Cisco TelePresence Immersive Endpoint System versions prior to 1.9.1 are vulnerable.
To exploit the vulnerability, an attacker must have access to an adjacent network in a physical or logical Layer 3 context to send malicious requests to port 61460 of the affected device. The attacker may need access to trusted, internal networks, which could limit the likelihood of a successful exploit. In addition, the attacker would also need to perform a three-way TCP handshake and establish a valid session to exploit this vulnerability.
This alert contains CVSS scoring supplied by Cisco, the primary vendor of the affected product. Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code on a targeted device with elevated privileges, possibly resulting in a complete compromise.
The vulnerability is due to improper processing of malformed requests by the affected software.
An unauthenticated, remote attacker with access to an adjacent network in a physical or logical Layer 3 context could exploit this vulnerability by sending crafted network requests to the targeted device on port 61460. When processed, the malicious requests could allow the attacker to execute arbitrary commands on the device that will be executed by the system with elevated privileges, possibly resulting in a complete compromise.
Administrators are advised to apply the appropriate updates.
Administrators are advised to implement an intrusion prevention system (IPS) or intrusion detection system (IDS) to help detect and prevent attacks that attempt to exploit this vulnerability.
Administrators are advised to monitor affected systems.
