Overview
Affected versions of this package are vulnerable to Command Injection via the NRDP process. An attacker can execute arbitrary OS commands by injecting malicious input into custom-variable macro values that are referenced in shell-executed command lines. This is only exploitable if a non-default configuration is used where a custom variable is defined and referenced in a shell-executed command.
