Siemens has published a document regarding the vulnerability affecting the SIMATIC S7-200, S7-300, S7-400, and S7-1200 products.
SIEMENS SIMATIC S7 1200 PDF HOW TO
Defense-in-depth strategies for both enterprise and control system networks see the ICS-CERT Recommended Practice document, Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies and Siemens’ Industrial Security website for more information on how to apply these measures.
SIEMENS SIMATIC S7 1200 PDF PASSWORD
Changing this password frequently and using unique passwords, when possible, will reduce exposure to this vulnerability.
SIEMENS SIMATIC S7 1200 PDF FULL
The full impact to individual organizations is dependent on multiple factors unique to each organization. IMPACTĪn attacker with access to the PLC or the automation network could intercept the PLC password and make unauthorized changes to the PLC operation. ICS-CERT will publish additional information as it becomes available.

Like ISO-TSAP, many protocols used in industrial control systems were intentionally designed to be open and without security features. According to ICS-CERT analysis, the ISO-TSAP protocol is functioning to specifications however, authentication is not performed nor are payloads encrypted or obfuscated. Siemens PLCs configured with password protection are still susceptible to a replay attack.Ĭommands between the affected PLCs and other devices are transmitted using the International Organization for Standardization Transport Service Access Point (ISO-TSAP) protocol. The replay attack vulnerabilities affecting the S7-1200 also are verified to affect the SIMATIC S7-200, S7-300, and S7-400 PLCs. Reported multiple vulnerabilities to ICS-CERT that affect the Siemens Simatic S7-1200 micro PLC as reported in ICS-ALERT-11-161-01. In May of 2011, security researcher Dillon Beresford of NSS Labs 1 ICS-CERT is continuing to coordinate with Siemens concerning vulnerabilities affecting Siemens SIMATIC Programmable Logic Controllers (PLCs).
