Last modified

CVE-2023-49565 is a high-severity vulnerability rated 8.4/10 on the CVSS scale. 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. EPSS estimates a 0.76% chance of exploitation in the next 30 days.

Description

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.
