Overview
Affected versions of this package are vulnerable to Improper Encoding or Escaping of Output via the getCommand process. An attacker can execute arbitrary operating system commands by supplying specially crafted values to the IN_FILE_ENDING or OUT_FILE_ENDING configuration keys, which are concatenated into shell command arguments without validation or escaping. This allows the injection of shell metacharacters that are interpreted by the shell, leading to full compromise of confidentiality, integrity, and availability of the system. This is only exploitable if the attacker has the ability to modify configuration files or set configuration keys.
