Description An OS command injection issue allows an administrator to execute arbitrary OS commands via a file name parameter in a patch application function. The Zultys MX Administrator client has a "Patch Manager" section that allows administrators to apply patches to the device. The user-supplied filename for the patch file is passed to a shell script without validation. Including bash command substitution characters in a patch file name results in execution of the provided command.

Recommendations For Zultys MX-SE, MX-SE II, MX-E, MX-Virtual, MX250, and MX30 with firmware versions prior to 17.0.10 patch 17161, update to version 17.0.10 patch 17161 or later. For Zultys MX-SE, MX-SE II, MX-E, MX-Virtual, MX250, and MX30 with firmware versions prior to 16.04 patch 16109, update to version 16.04 patch 16109 or later. As a temporary workaround, consider validating the filename for the patch file before passing it to the shell script to prevent command injection.
