What is CVE-2024-20483?

CVE-2024-20483 is a high-severity command injection vulnerability in Cisco Ios Xr, published on 11 Sep 2024. An attacker needs administrator access to exploit it, with no action from the victim.

Official description

Multiple vulnerabilities in Cisco Routed PON Controller Software, which runs as a docker container on hardware that is supported by Cisco IOS XR Software, could allow an authenticated, remote attacker with Administrator-level privileges on the PON Manager or direct access to the PON Manager MongoDB instance to perform command injection attacks on the PON Controller container and execute arbitrary commands as root. These vulnerabilities are due to insufficient validation of arguments that are passed to specific configuration commands. An attacker could exploit these vulnerabilities by including crafted input as the argument of an affected configuration command. A successful exploit could allow the attacker to execute arbitrary commands as root on the PON controller.
