CVE-2018-0167

CVSS 8.8 HIGHEPSS 3.4%● KEVCWE-119
In short

A flaw in Cisco's network discovery system allows attackers on the same network to crash devices or take control of them without needing a password. The problem is caused by improper handling of data that exceeds expected limits.

Technical detail

Multiple buffer overflow vulnerabilities in the LLDP subsystem allow an unauthenticated, adjacent network attacker to trigger denial of service or arbitrary code execution with elevated privileges. The vulnerability requires network proximity but no authentication, exploiting improper input validation in protocol message handling.

Summary generated and translated by AI from the official description.
Multiple Buffer Overflow vulnerabilities in the Link Layer Discovery Protocol (LLDP) subsystem of Cisco IOS Software, Cisco IOS XE Software, and Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition or execute arbitrary code with elevated privileges on an affected device. Cisco Bug IDs: CSCuo17183, CSCvd73487.
