Video Surveillance 8000P Ip Camera Firmware CVE-2021-1131

This vulnerability is classified as Buffer Overflow (CWE-119), which allows attackers to corrupt memory to execute arbitrary code or crash the application. 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). Affected products include: Cisco Video Surveillance 8000P Ip Camera Firmware, Cisco Video Surveillance 8020 Ip Camera Firmware, Cisco Video Surveillance 8030 Ip Camera Firmware, Cisco Video Surveillance 8070 Ip Camera Firmware, Cisco Video Surveillance 8400 Ip Camera Firmware.
