CVE-2020-3110Cisco Video Surveillance 8000 Series IP Cameras Cisco Discovery Protocol Remote Code Execution and Denial of Service Vulnerability
High 8.8
In plain English
A high-severity improper input validation in Cisco Video Surveillance 8000 Series IP Cameras from Cisco. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 5.7% (higher than 93% of all known vulnerabilities).
Official description
A vulnerability in the Cisco Discovery Protocol implementation for the Cisco Video Surveillance 8000 Series IP Cameras could allow an unauthenticated, adjacent attacker to execute code remotely or cause a reload of an affected IP Camera. The vulnerability is due to missing checks when processing Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to the targeted IP Camera. A successful exploit could allow the attacker to expose the affected IP Camera for remote code execution or cause it to reload unexpectedly, resulting in a denial of service (DoS) condition. 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). This vulnerability is fixed in Video Surveillance 8000 Series IP Camera Firmware Release 1.0.7 and later.
