What is CVE-2018-0088?
CVE-2018-0088 is a medium-severity memory corruption vulnerability in Cisco IOS, published on 18 Jan 2018. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
A vulnerability in one of the diagnostic test CLI commands on Cisco Industrial Ethernet 4010 Series Switches running Cisco IOS Software could allow an authenticated, local attacker to impact the stability of the device. This could result in arbitrary code execution or a denial of service (DoS) condition. The attacker has to have valid user credentials at privilege level 15. The vulnerability is due to a diagnostic test CLI command that allows the attacker to write to the device memory. An attacker could exploit this vulnerability by authenticating to the targeted device and issuing a specific diagnostic test command at the CLI. An exploit could allow the attacker to overwrite system memory locations, which could have a negative impact on the stability of the device. Cisco Bug IDs: CSCvf71150.
