Armatura One stores database and message-broker credentials in an install configuration file, encrypting them with AES-128-CBC when this protection is enabled. The encryption key and initialization vector are fixed values embedded in the software itself and are identical across every installation. An attacker with a copy of the installation package can recover this key and initialization vector, and can then decrypt the stored credentials of any specific installation to which the attacker separately obtains the encrypted configuration file.
