VAPT: Siemens S7 1200/1500 Project Password Vuln

[groot]

I specialize in industrial cybersecurity, with a current research focus on the security mechanisms in Siemens TIA Portal—specifically FB/POU and project password protection. My work involves testing these features up to TIA Portal V20 and analyzing their impact on engineering workflows in OT environments.

 

During authorized testing on S7-1200 and S7-1500 PLCs with TIA Portal V19, I successfully retrieved project data. A core finding is the significant role of version compatibility in data accessibility. Additionally, this exercise reinforced that project protection settings are a critical variable, directly influencing recoverability and must be carefully considered in security research and OT risk assessments.

 

My hands-on experience is primarily with S7-1200 and S7-1500 PLCs, spanning programming, troubleshooting, and authorized security testing. I'm here to share insights from my research, discuss practical implications, and learn from others in the OT security community.

Looking forward to your insight !
