CVE-2025-49213Network attack vector

Pre-authentication code execution via untrusted deserialization

Published Jun 17, 2025 · Updated Jun 18, 2025

Insecure deserialization in Trend Micro Endpoint Encryption PolicyServer before 6.0.0.4013 allows remote attackers to execute SYSTEM code. PolicyServerWindowsService fails to validate user-supplied data before deserializing it, allowing attacker-controlled data to trigger code execution. Authentication is not required, and successful exploitation grants arbitrary code execution with SYSTEM privileges.
