Last modified

CVE-2020-3506 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. Multiple vulnerabilities in the Cisco Discovery Protocol implementation for 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. These vulnerabilities are due to missing checks when the IP cameras process a Cisco Discovery Protocol packet. EPSS estimates a 0.95% chance of exploitation in the next 30 days.

Description

Multiple vulnerabilities in the Cisco Discovery Protocol implementation for 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. These vulnerabilities are due to missing checks when the IP cameras process a Cisco Discovery Protocol packet. An attacker could exploit these vulnerabilities by sending a malicious Cisco Discovery Protocol packet to the targeted IP camera. A successful exploit could allow the attacker to execute code on the affected IP camera or cause it to reload unexpectedly, resulting in a denial of service (DoS) condition. Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit these vulnerabilities, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).
