Deploy openPDC from source or use alternative distribution methods; if Docker images must be used, immediately change administrative credentials after deployment and restrict network access to the management interface using firewall rules.</anigation> </invoke>

Technical details

The openPDC Docker image ships with hardcoded administrative credentials and lacks forced credential change on initial deployment. An unauthenticated network attacker can authenticate to the management interface using these credentials, gaining complete administrative access to the application. This vulnerability affects the Docker image distribution only; the vendor does not plan to fix it in the published images.

Affected products
