Protected-picture disclosure via insecure password verification
Published Feb 9, 2021 · Updated Aug 4, 2024
Authentication bypass in SIMATIC WinCC before 7.5 SP2 and all SIMATIC PCS 7 versions allows physically proximate attackers to read protected pictures. The Graphics Designer tool uses an insecure password-verification process for password-protected picture files, allowing the protection to be bypassed. Physical access to a machine running the software is required; the consequence is disclosure of private picture content only.
