Summary
A vulnerability has been identified in LOGO! Soft Comfort (All versions < V9). Affected products use a static, hardcoded AES master key to encrypt project files. This could allow a local attacker to extract the master key from the application files or memory and use it to decrypt project files or remove project passwords entirely without knowing the actual user-defined password.
