All versions of the TWinSoft Configuration Tool store encrypted passwords as plaintext in memory. An attacker with access to system files could open a file to load the document into memory, including sensitive information associated with document, such as password. The attacker could then obtain the plaintext password by using a memory viewer.

The affected TBox RTUs generate software security tokens using insufficient entropy. The random seed used to generate the software tokens is not initialized correctly, and other parts of the token are generated using predictable time-based values. An attacker with this knowledge could successfully brute force the token and authenticate themselves.
