AI-suggested

If you cannot patch yet, restrict administrative access and carefully validate update bundles before installation.

Description

Two OS command injection vulnerabilities exist in the update installation functionality due to insufficient validation of update bundle contents. An attacker with administrative privileges can remotely supply a crafted update bundle that executes arbitrary commands with root privileges. This allows reading or modifying sensitive data, changing appliance configuration, or shutting down the appliance.
