CVE-2025-49212
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn insecure deserialization operation in the Trend Micro Endpoint Encryption PolicyServer could lead to a pre-authentication remote code execution on affected installations. Note that this vulnerability is similar to CVE-2025-49220 but is in a different method.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceTrend Micro Endpoint Encryption PolicyServer contains an insecure deserialization vulnerability that allows unauthenticated attackers to execute arbitrary code remotely. This stems from improper handling of serialized data, enabling attackers to craft malicious payloads that deserialize into executable code without any authentication credentials.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the PolicyServer installation directoryOn the server hosting PolicyServer, check common installation paths such as C:\Program Files\Trend Micro\Endpoint Encryption\PolicyServer or C:\Program Files (x86)\Trend Micro\Endpoint Encryption\PolicyServer. Look for the PolicyServer.exe or PolicyServerService.exe executable.Affected if The PolicyServer executable is present on the system.
-
Identify the installed Endpoint Encryption versionRight-click on PolicyServer.exe, select Properties, then go to the Details tab and check the Product Version field. Alternatively, open Windows Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\EndpointEncryption\PolicyServer (or the corresponding Wow6432Node path) and read the Version or ProductVersion value.Affected if The installed version is lower than 6.0.0.4013.
-
Verify PolicyServer service statusOpen Windows Services (services.msc) and locate the Trend Micro PolicyServer service. Check if it is running or set to start automatically.Affected if The PolicyServer service is installed and running.
-
Assess network exposure of PolicyServerReview firewall rules and network configuration to determine which network interfaces the PolicyServer listens on. Check if the PolicyServer port (default TCP 8080 or as configured) is exposed to untrusted networks or the internet. Use netstat -an | findstr LISTENING to identify listening ports.Affected if PolicyServer is bound to IPs accessible from untrusted networks or the internet.
-
Confirm deserialization endpoint availabilityIf possible, verify that the PolicyServer web service or API endpoint is accessible over the network. This typically responds on HTTP/HTTPS ports used for client communication.Affected if The PolicyServer management interface is network-accessible without authentication restrictions.
A system is affected if Trend Micro Endpoint Encryption PolicyServer is installed with a version lower than 6.0.0.4013 and the service is accessible over the network.
