CVE-2021-1131 Information

Description

A vulnerability in the Cisco Discovery Protocol implementation for Cisco Video Surveillance 8000 Series IP Cameras could allow an unauthenticated adjacent attacker to cause an affected IP camera to reload. The vulnerability is due to missing checks when Cisco Discovery Protocol messages are processed. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected IP camera. A successful exploit could allow the attacker to cause the affected IP camera to reload unexpectedly resulting in a denial of service (DoS) condition. Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).
