CVE-2020-25241

Name of the Vulnerable Software and Affected Versions: SIMATIC MV400 family versions prior to V7.0.6

Description: A vulnerability has been identified in the SIMATIC MV400 family. 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.

Recommendations: For versions prior to V7.0.6, update to version V7.0.6 or later to resolve the issue. As a temporary workaround, consider restricting access to the TCP stack to minimize the risk of exploitation.
