CVE-2025-34419
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 · uneditedMailEnable versions prior to 10.54 contain an unsafe DLL loading vulnerability that can lead to local arbitrary code execution. The MailEnable administrative executable attempts to load MEAISM.DLL from its installation directory without sufficient integrity validation or a secure search order. A local attacker with write access to that directory can plant a malicious MEAISM.DLL, which is then loaded when the executable starts, resulting in execution of attacker-controlled code with the privileges of the process.
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.

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 MailEnable installation path and versionLocate the MailEnable installation directory (typically C:\Program Files\MailEnable or C:\Program Files (x86)\MailEnable). Check the version of the administrative executable (MEAdmin.exe or similar) by right-clicking the file, selecting Properties, and viewing the Details tab or version info.Affected if The installed version is earlier than 10.54 (e.g., 10.53, 10.52, etc.)
-
Verify MEAISM.DLL presence in installation directoryNavigate to the MailEnable installation directory and confirm that MEAISM.DLL exists in that location. The vulnerability specifically concerns this DLL being loaded from the installation directory.Affected if MEAISM.DLL exists in the MailEnable installation directory (the vulnerable DLL loading path)
-
Check write permissions on the MailEnable installation directoryRight-click the MailEnable installation folder, select Properties, go to the Security tab, and review the permissions. Alternatively, use icacls.exe from an elevated command prompt: icacls "C:\Program Files\MailEnable" (or your specific path).Affected if Users other than Administrators or the SYSTEM account have Write or Modify permissions to the installation directory, allowing them to plant a malicious DLL
You are affected if MailEnable version is below 10.54 AND MEAISM.DLL is present in the installation directory AND unauthorized users have write access to that directory.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped10.54
Upgrade to MailEnable version 10.54 or later. Additionally, restrict write permissions on the MailEnable installation directory to prevent unauthorized users from planting malicious DLLs.
MailEnable 10.54
- Back up the current MailEnable installation and configuration before upgrading.
- Download MailEnable version 10.54 from the official MailEnable website (www.mailenable.com).
- Stop the MailEnable services to ensure a clean upgrade process.
- Run the MailEnable 10.54 installer and follow the vendor's upgrade instructions.
- Restart the MailEnable services after the upgrade completes.
- Verify that the administrative interface loads correctly and the MEAISM.DLL is loaded from the proper secure location.
