UD-LT1 firmware Ver.2.1.9 and earlier and UD-LT1/EX firmware Ver.2.1.9 and earlier allow a remote authenticated attacker with an administrative account to execute arbitrary OS commands.
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
