SSA-222768 PUBLISHED CVSS 7.5 HIGH

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.
