CVE-2023-32737

A vulnerability has been identified in SIMATIC STEP 7 Safety V18 (All versions < V18 Update 2). Affected applications do not properly restrict the .NET BinaryFormatter when deserializing user-controllable input. This could allow an attacker to cause a type confusion and execute arbitrary code within the affected application. This is the same issue that exists for .NET BinaryFormatter https://docs.microsoft.com/en-us/visualstudio/code-quality/ca2300.

Summary		(es) Se ha identificado una vulnerabilidad en SIMATIC STEP 7 Safety V18 (todas las versiones < V18 Update 2). Las aplicaciones afectadas no restringen adecuadamente .NET BinaryFormatter al deserializar la entrada controlable por el usuario. Esto podría permitir que un atacante cause confusión de tipos y ejecute código arbitrario dentro de la aplicación afectada. Este es el mismo problema que existe para .NET BinaryFormatter https://docs.microsoft.com/en-us/visualstudio/code-quality/ca2300.
