Vulnerability from variot
A vulnerability in the Cisco Discovery Protocol (CDP) module of Cisco IOS XE Software Releases 16.6.1 and 16.6.2 could allow an unauthenticated, adjacent attacker to cause a memory leak that may lead to a denial of service (DoS) condition. The vulnerability is due to incorrect processing of certain CDP packets. An attacker could exploit this vulnerability by sending certain CDP packets to an affected device. A successful exploit could cause an affected device to continuously consume memory and eventually result in a memory allocation failure that leads to a crash, triggering a reload of the affected device. Cisco IOS XE The software is vulnerable to resource exhaustion.Service operation interruption (DoS) There is a possibility of being put into a state. Cisco IOSXESoftware is a set of operating systems developed by Cisco for its network devices. Cisco Discovery Protocol (CDP) is one of the device discovery modules. An attacker with a physical location nearby can exploit the vulnerability to cause a denial of service (crash). Attackers can exploit this issue to reload the affected device, denying service to legitimate users This issue is being tracked by Cisco Bug ID CSCvf50648
