Published: Translated: NVD NIST

Summary

A vulnerability in the SIP protocol of Cisco TelePresence Codec and Collaboration Endpoint software could allow an unauthenticated, remote attacker to cause a TelePresence endpoint to reload unexpectedly, resulting in a denial of service (DoS) condition. The issue is due to a lack of flow-control mechanisms within the software.

Risk Assessment

An attacker could impact the availability of services and data of the device, potentially leading to a complete DoS condition. Organizations using affected platforms are at risk of service outages.

Recommendation

It is recommended to update the software to versions TC 7.3.8 or CE 8.3.0 to mitigate this vulnerability. Monitoring SIP traffic for potential attacks may also help secure the system.
