Vulnerability details

The vulnerability allows an adjacent unauthenticated attacker to cause DoS condition or execute arbitrary code with elevated privileges on the target system.

The weakness exists in the LLDP subsystem due to improper handling of certain fields in an LLDP message. An adjacent attacker can submit a specially crafted LLDP PDU, trick the victim into executing a specific show command in the CLI, trigger memory corruption, cause the service to crash or execute arbitrary code with root privileges.

Successful exploitation of the vulnerability may result in system compromise.
