Design/Logic Flaw

A vulnerability has been identified in SIMATIC S7-PLCSIM V5.4 All versions. An attacker with local access to the system could cause a Denial-of-Service condition in the application when it is used to open a specially crafted file. As a consequence, a divide by zero operation could occur and cause...

Design/Logic Flaw

A vulnerability has been identified in SIMATIC MV400 family All Versions V7.0.6. The underlying TCP stack of the affected products does not correctly validate the sequence number for incoming TCP RST packages. An attacker could exploit this to terminate arbitrary TCP sessions...

CVE-2021-25674

CVE-2021-25674 affects SIMATIC S7-PLCSIM v5.4 (all versions) where opening a specially crafted file can trigger a NULL pointer dereference, causing the application to terminate and require restart. The vulnerability is locally exploitable; no remote access is indicated. Connected sources corrobor...
