Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection via the restore process. An attacker can execute arbitrary OS commands by uploading a crafted backup archive that overwrites the application's configuration file and database, injecting malicious commands into the TestConfigCmd setting. This is only exploitable if the application is accessed within the first 10 minutes after process startup on a fresh installation.
