Published · Updated
E-mail alert when it lands in KEV, gets a public PoC or its score goes up.
No sign of exploitation. No public exploitation artifact known so far.
A flaw in Cisco TelePresence and RoomOS devices allows attackers to crash or restart these video conferencing systems by sending specially crafted network traffic, without needing any password or authentication.
Insufficient input validation in H.323 packet processing allows unauthenticated remote attackers to send malformed H.323 traffic that triggers device reboot or maintenance mode entry, resulting in denial of service. Attack requires no credentials and can be delivered over the network to affected endpoints.
In the same product, most dangerous first.
