Risk evaluation
SIMATIC S7-PLCSIM Advanced contains a vulnerability that could allow an attacker to cause a denial of service condition. Siemens is preparing fix versions and recommends specific countermeasures for products where fixes are not, or not yet available.
Mitigation summary
Disable the S7-PLCSIM Virtual Switch binding on the network adapter used by the affected instance. This prevents the adapter from entering an external communication mode and removes the attack vector entirely. (see SIMATIC S7-PLCSIM Advanced Function Manual V8.0, 11/2025 Section 5.3 and Section 6.1.2.3; and SIMATIC S7-PLCSIM Advanced Function Manual API V8.0, 11/2025 Section 7.2)
