CVE-2026-54429
CVE-2026-54429 updated by NVD
Summary
A vulnerability has been identified in SIMATIC S7-PLCSIM Advanced (All versions). Affected devices do not properly handle high-volume multicast network traffic, which can exhaust available memory resources in the affected application. This could allow an unauthenticated attacker on the local network segment to cause a denial-of-service condition of the affected application. The affected application becomes inaccessible and requires a manual restart; no project data is lost. Successful exploitation requires a specific project configuration to be already active on the targeted instance.
