SSA-222768

Vulnerability from csaf_siemens - Published: 2025-05-13 00:00 - Updated: 2025-05-13 00:00

Summary

SSA-222768: Multiple Vulnerabilities in SIRIUS 3SK2 Safety Relays and 3RK3 Modular Safety Systems

Notes

Summary: SIRIUS 3SK2 Safety Relays and 3RK3 Modular Safety Systems only provide weak password obfuscation. An attacker with access to the PROFINET or serial interface of the device could eavesdrop or read the stored password from the device and de-obfuscate it. The safety passwords work as protection against unauthorized operation (i.e., protection against inadvertent operating errors) but not as protection against malicious access attempts. Siemens is preparing fix versions and recommends countermeasures for products where fixes are not, or not yet available.

General Recommendations: As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity

Additional Resources: For further inquiries on security vulnerabilities in Siemens products and solutions, please contact the Siemens ProductCERT: https://www.siemens.com/cert/advisories
