  - The MD5 Message-Digest Algorithm does not provide enough collision resistance

  - A flaw in Inductive Automation Ignition that is triggered when resetting the
    session ID parameter via a HTTP request.

  - A flaw in the web interface that is due to a missing session termination once
    a user logs out.

  - A flaw in application that is due to the program storing OPC server credentials
    in plaintext.

  - A flaw in application that is triggered when an unhandled exception occurs,
    which can cause an error or warning message.

  - The application does not validate input before returning it to users.");
