Technical Description
An issue was discovered on DCN (Digital China Networks) S4600-10P-SI devices before R0241.0470. Due to improper parameter validation in the console interface, it is possible for a low-privileged authenticated attacker to escape the sandbox environment and execute system commands as root via shell metacharacters in the capture command parameters. Command output will be shown on the Serial interface of the device. Exploitation requires both credentials and physical access.
Remediation
Check the references section for vendor advisories and patches from dcnglobal. Update s4600-10p-si_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
