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.

Siemens LOGO! Soft Comfort contains multiple vulnerabilities in its project-file encryption and password handling mechanisms. A local attacker could exploit these vulnerabilities to extract the master key, allowing them to decrypt project data or remove project passwords. The lack of password salting enables offline dictionary or brute-force attacks against the password hashes. Successful exploitation could result in unauthorized access to, or modification of, sensitive project logic and configurations. Siemens has released a new version for LOGO! Soft Comfort and recommends to update to the latest version.
