Detailsinfo

A vulnerability has been found in Cisco IOS XR 24.1.1/24.1.2/24.2.1/24.2.11/24.3.1 and classified as critical. This vulnerability affects an unknown functionality of the component Routed PON Controller Software. The manipulation with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at sec.cloudapps.cisco.com. This vulnerability was named CVE-2024-20483 since 11/08/2023. The exploitation appears to be easy. The attack can be initiated remotely. Additional levels of successful authentication are required for exploitation. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $5k-$25k at the moment (estimation calculated on 10/03/2024). This vulnerability is assigned to T1202 by the MITRE ATT&CK project.
