CVE-2023-32737 (GCVE-0-2023-32737)

Vulnerability from cvelistv5 – Published: 2024-07-09 12:04 – Updated: 2025-08-27 20:32

Summary

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.
