Detailsinfo

A vulnerability was found in Nokia CBIS and NCS (unknown version). It has been classified as critical. Affected is an unknown code block of the file /api/plugins of the component Header Handler. The manipulation with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The cbis_manager Podman container is vulnerable to remote command execution via the /api/plugins endpoint. Improper sanitization of the HTTP Headers X-FILENAME, X-PAGE, and X-FIELD allows for command injection. These headers are directly utilized within the subprocess.Popen Python function without adequate validation, enabling a remote attacker to execute arbitrary commands on the underlying system by crafting malicious header values within an HTTP request to the affected endpoint. The web service executes with root privileges within the container environment, the demonstrated remote code execution permits an attacker to acquire elevated privileges for the command execution. Restricting access to the management network with an external firewall can partially mitigate this risk.

The weakness was presented by Firewall. The advisory is available at nokia.com. This vulnerability is traded as CVE-2023-49565 since 11/27/2023. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 09/21/2025). This vulnerability is assigned to T1202 by the MITRE ATT&CK project.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
