CVE-2020-25241

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-2019-10925

A vulnerability has been identified in SIMATIC MV400 family All Versions V7.0.6. An authenticated attacker could escalate privileges by sending specially crafted requests to the integrated webserver. The security vulnerability can be exploited by an attacker with network access to the device. Val...

CVE-2020-27632

The CVE-2020-27632 issue affects the SIMATIC MV400 family prior to v7.0.6. The root cause is that the ISN generator is initialized with a constant value and uses constant increments, making initial sequence numbers highly predictable. This can enable an attacker to predict and hijack TCP sessions...
