CVE-2025-34416
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 MEAIPO.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 MEAIPO.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.
dbcve analysis · high confidenceMailEnable versions prior to 10.54 contain an unsafe DLL loading vulnerability where the administrative executable (MEADMIN.EXE) attempts to load MEAIPO.DLL from its installation directory without secure search order or integrity validation. A local attacker with write access to the MailEnable installation directory can plant a malicious MEAIPO.DLL that gets loaded when the admin tool starts, resulting in arbitrary code execution with process privileges.

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 MailEnable installation and versionOpen Windows Registry and check the version under HKLM\SOFTWARE\MailEnable\Admin or look in the installation directory for MEADMIN.EXE. Right-click the executable, select Properties, and view the Version tab to find the FileVersion.Affected if The installed version is lower than 10.54 (e.g., 10.53, 10.52, etc.)
-
Verify MEAIPO.DLL exists in installation directoryNavigate to the MailEnable installation folder (commonly C:\Program Files\MailEnable or C:\Program Files (x86)\MailEnable) and confirm that MEAIPO.DLL is present in the same directory as MEADMIN.EXE.Affected if MEAIPO.DLL exists in the installation directory alongside MEADMIN.EXE
-
Check write permissions on the installation directoryRight-click the MailEnable installation folder, select Properties, go to the Security tab, and review the permissions for Users and other non-privileged accounts. Alternatively, run 'icacls <installation_path>' from an elevated command prompt.Affected if Non-administrative users or groups have Write or Modify permissions to the MailEnable installation directory
-
Confirm MEADMIN.EXE is the targeted executableVerify that MEADMIN.EXE exists in the MailEnable installation directory - this is the administrative tool that loads MEAIPO.DLL without secure DLL loading.Affected if MEADMIN.EXE is present and accessible in the installation directory
You are affected if MailEnable version is below 10.54 and the installation directory grants write access to untrusted users, allowing potential DLL planting.

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
Primary remediation is to upgrade to MailEnable version 10.54 or later. As an immediate workaround, restrict write permissions on the MailEnable installation directory to prevent unauthorized DLL planting by non-privileged users.
10.54
- Obtain MailEnable version 10.54 or later from the official vendor (mailenable.com)
- Ensure you have backups of MailEnable configuration and data before upgrading
- Apply the upgrade to the MailEnable installation
- After upgrade, verify the installation directory permissions - ensure only trusted administrators have write access to the MailEnable program directory
- Restart the MailEnable services to ensure the patched executable loads properly
