Unauthenticated code execution via unsafe deserialization
Published Jul 21, 2025 · Updated Jul 21, 2025
Insecure deserialization in Simopro Technology WinMatrix3 3.8.52.5 and earlier allows remote attackers to execute arbitrary code. The server processes malicious serialized content through an unsafe deserialization path, but the affected endpoint, serializer, and missing validation are undisclosed. No credentials or user interaction are required, and successful exploitation permits arbitrary server-side code execution.
