Name of the Vulnerable Software and Affected Versions Cisco Video Surveillance 8000 Series IP Cameras (affected versions not specified)

Description A vulnerability in the Cisco Discovery Protocol implementation could allow an unauthenticated, adjacent attacker to execute arbitrary code on an affected device or cause the device to reload. This issue is due to missing checks when an IP camera processes a Cisco Discovery Protocol packet. An attacker could exploit this by sending a malicious Cisco Discovery Protocol packet to an affected device, potentially allowing the execution of code on the affected IP camera or causing it to reload unexpectedly, resulting in a denial of service (DoS) condition. The attacker must be in the same broadcast domain as the affected device to exploit this vulnerability.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
