CVE-2022-20793Network attack vector

Unauthenticated device access via pairing impersonation

Published Nov 15, 2024 · Updated Nov 15, 2024

Authentication bypass in Cisco TelePresence CE and RoomOS Software allows remote attackers to pair with an endpoint as a trusted Touch 10 device. During pairing, the endpoint accepts a response to its discovery broadcast without sufficiently verifying the responder's identity. Exploitation requires participation in the pairing exchange and grants access with the impersonated device's trust, without reported availability impact.
