Siemens SIMATIC S7-PLCSIM Advanced
Siemens SIMATIC S7-PLCSIM Advanced contains a denial of service vulnerability (CVE-2026-54429) with a CVSS score of 7.4 that allows unauthenticated attackers on the local network to exhaust memory by sending high-volume multicast traffic, rendering the affected application inaccessible until manual restart. No fix is currently available, but Siemens recommends disabling the virtual switch binding, restricting multicast traffic on the network segment, or using the default Softbus network mode as mitigations.
Why it matters: Organizations running SIMATIC S7-PLCSIM Advanced in environments exposed to untrusted local networks need immediate mitigation steps to prevent operational disruption of critical manufacturing simulation and control system testing infrastructure.
