Password disclosure via cleartext process memory
Published Dec 12, 2023 · Updated Nov 25, 2024
Information disclosure in Siemens SIMATIC STEP 7 (TIA Portal) before 19 allows local users to read S7 CPU access-level passwords. The hardware configuration workflow retains the entered controller password in cleartext process memory accessible to a privileged local process. Exploitation requires high local privileges and user interaction while a legitimate user supplies the password, exposing the credential without changing data or service.
