What is CVE-2023-20015?
CVE-2023-20015 is a medium-severity command injection vulnerability in Cisco Firepower Extensible Operating System, published on 23 Feb 2023. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
A vulnerability in the CLI of Cisco Firepower 4100 Series, Cisco Firepower 9300 Security Appliances, and Cisco UCS 6200, 6300, 6400, and 6500 Series Fabric Interconnects could allow an authenticated, local attacker to inject unauthorized commands. This vulnerability is due to insufficient input validation of commands supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to the affected command. A successful exploit could allow the attacker to execute unauthorized commands within the CLI. An attacker with Administrator privileges could also execute arbitrary commands on the underlying operating system of Cisco UCS 6400 and 6500 Series Fabric Interconnects with root-level privileges.
Weakness: CWE-78
