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 · unedited
An insecure deserialization operation in the Trend Micro Endpoint Encryption PolicyServer could lead to a post-authentication remote code execution on affected installations. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system to exploit this vulnerability.

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 confidence

Trend Micro Endpoint Encryption PolicyServer contains an insecure deserialization vulnerability that allows an authenticated attacker to deserialize untrusted data, potentially leading to arbitrary code execution on the affected system. The attacker must first obtain low-privileged code execution capabilities before leveraging this flaw to escalate privileges and achieve full RCE.

MitigationApply the vendor-provided security patch for Trend Micro Endpoint Encryption PolicyServer when available, and restrict administrative access to trusted personnel only until the patch can be deployed.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if PolicyServer component is installed
    Locate the Trend Micro Endpoint Encryption PolicyServer installation directory or check installed programs for the PolicyServer component
    Affected if PolicyServer is present and running on the system
  2. Determine installed version of Trend Micro Endpoint Encryption
    Use the vendor's standard method to retrieve the product version (such as checking the About dialog in the management console, reviewing the installer version, or querying the installed packages)
    Affected if The version retrieved is lower than 6.0.0.4013
  3. Confirm PolicyServer service is accessible
    Verify the PolicyServer service is running and network-accessible (check service status, listening ports, or management console accessibility)
    Affected if PolicyServer is active and accepting authenticated connections
  4. Verify user access controls on PolicyServer
    Review the authentication configuration and user permissions configured in PolicyServer to determine if low-privileged accounts can interact with the deserialization endpoint
    Affected if Low-privileged or untrusted users have authenticated access to PolicyServer interfaces

Your environment is affected if Trend Micro Endpoint Encryption PolicyServer is installed with a version lower than 6.0.0.4013 and is accessible to authenticated users.

Upgrade available Upgrade to 6.0.0.4013 or later
Fixed in 6.0.0.4013
Interim mitigation

Apply the vendor-provided security patch for Trend Micro Endpoint Encryption PolicyServer when available, and restrict administrative access to trusted personnel only until the patch can be deployed.

Recommended fix Moderate confidence

Trend Micro Endpoint Encryption 6.0.0.4013 or later

  1. 1. Identify the current installed version of Trend Micro Endpoint Encryption PolicyServer by checking the application version in Programs and Features or the PolicyServer management console.
  2. 2. If the current version is below 6.0.0.4013, obtain the updated installer from the official Trend Micro support portal at success.trendmicro.com.
  3. 3. Before applying the update, ensure you have a complete backup of the PolicyServer database and configuration settings.
  4. 4. Apply the update in accordance with Trend Micro's standard upgrade procedures, typically by running the installer on the PolicyServer system.
  5. 5. After upgrade, verify the PolicyServer service is running correctly and confirm the new version displays as 6.0.0.4013 or higher.
  6. 6. Test that endpoint encryption clients can successfully communicate with the updated PolicyServer.
Caveat Standard upgrade considerations apply - test in non-production first, ensure backup of database and configuration before proceeding
