CVE-2025-49213
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-2025-49212 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 allowing unauthenticated remote code execution. Attackers can exploit this by sending specially crafted serialized data to the PolicyServer, which deserializes it without proper validation, enabling arbitrary code execution on the target system.

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.
-
Identify installed Trend Micro Endpoint Encryption versionCheck the installed version of Trend Micro Endpoint Encryption on the system. On Windows, this can typically be found in Add/Remove Programs, or check the PolicyServer installation directory for version information in registry or a version file.Affected if The installed version is lower than 6.0.0.4013 (e.g., 6.0.0.x where x < 4013, or any version prior to 6.0)
-
Confirm PolicyServer component is installedVerify if the PolicyServer component is present on the system. This is typically installed as a Windows service named 'PolicyServer' or similar, and listens on a configurable port (often 8080 or 8443). Check Windows Services console or look for PolicyServer installation directories.Affected if PolicyServer is installed and running as a service on the system
-
Check network exposure of PolicyServerDetermine if the PolicyServer is accessible from the network. Use netstat or similar tools to identify which network interfaces and ports PolicyServer is bound to. Check if it listens on 0.0.0.0 or is accessible externally versus only on localhost/internal interfaces.Affected if PolicyServer is listening on externally accessible network interfaces (0.0.0.0) without proper network segmentation
-
Review PolicyServer access logs for anomalous requestsExamine PolicyServer access logs or IIS/Apache logs for unusual serialized data patterns, unexpected endpoints being hit, or signs of deserialization attempts. Look for large or base64-encoded payloads in request bodies.Affected if Logs show unexpected serialized data payloads or patterns indicative of deserialization exploitation attempts
-
Check for unauthorized code execution indicatorsReview system processes, scheduled tasks, and services created around the time of potential exploitation. Look for new suspicious executables, unexpected service installations, or lateral movement indicators originating from the PolicyServer host.Affected if Unexpected processes, services, or scheduled tasks exist on the PolicyServer system that were not authorized
A system is affected if Trend Micro Endpoint Encryption PolicyServer version is below 6.0.0.4013 and the PolicyServer component is network-accessible, making it vulnerable to unauthenticated remote code execution via insecure deserialization.

dbcve · scoped6.0.0.4013
Apply the vendor-provided security patch for CVE-2025-49213 immediately, as this is a critical pre-authentication RCE with CVSS 9.8. If no patch is available, consider network segmentation to limit PolicyServer exposure and monitor for anomalous deserialization activity.
Trend Micro Endpoint Encryption version 6.0.0.4013 or later
- 1. Identify the Trend Micro Endpoint Encryption PolicyServer installation in your environment
- 2. Verify the current installed version of Trend Micro Endpoint Encryption PolicyServer
- 3. Obtain the updated version 6.0.0.4013 or later from Trend Micro's official download channels or contact Trend Micro support
- 4. Review the upgrade prerequisites and documentation provided by Trend Micro
- 5. Schedule a maintenance window to apply the update
- 6. Apply the upgrade to the PolicyServer component
- 7. Verify the upgrade was successful by confirming the new version number
- 8. Test that the Trend Micro Endpoint Encryption management console is accessible and functioning properly
