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
MailEnable 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 MEAIPC.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 MEAIPC.DLL, which is then loaded on execution, resulting in attacker-controlled code running 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 confidence

MailEnable versions before 10.54 suffer from an unsafe DLL loading vulnerability where the administrative executable attempts to load MEAIPC.DLL from its installation directory without validating the DLL's integrity or using a secure search order. A local attacker with write access to the MailEnable installation directory can place a malicious MEAIPC.DLL that gets loaded when the admin tool runs, executing attacker-controlled code with the privileges of the administrative process.

MitigationUpgrade to MailEnable version 10.54 or later to obtain the vendor patch. As a compensating control, restrict write access to the MailEnable installation directory to only trusted administrators until the patch is applied.

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 MailEnable installation path and version
    Locate the MailEnable installation directory (commonly C:\Program Files\MailEnable or C:\Program Files (x86)\MailEnable) and check the version of MEADMIN.exe or the main executable. Use 'dir' or Windows Explorer to find version information in file properties, or check the registry under HKLM\SOFTWARE\MailEnable\Installed-Version if available.
    Affected if The installed version number is less than 10.54 (e.g., 10.53, 10.50, etc.)
  2. Verify MEAIPC.DLL exists in installation directory
    Check if MEAIPC.DLL file is present in the MailEnable installation directory using 'dir C:\Path\To\MailEnable\MEAIPC.DLL' or File Explorer.
    Affected if MEAIPC.DLL exists in the MailEnable installation folder (the vulnerable DLL that gets loaded by the admin tool)
  3. Check write permissions on MailEnable directory
    Use icacls or right-click the MailEnable installation folder > Properties > Security to review write permissions. Run 'icacls "C:\Program Files\MailEnable"' to list permissions for users and groups.
    Affected if Non-administrator or untrusted users have Write or Write+Execute permissions to the MailEnable installation directory, allowing them to replace MEAIPC.DLL

You are affected if MailEnable version is below 10.54 AND the installation directory is writable by untrusted users, enabling a local attacker to place a malicious MEAIPC.DLL that executes when the admin tool runs.

Upgrade available Upgrade to 10.54 or later
Fixed in 10.54
Interim mitigation

Upgrade to MailEnable version 10.54 or later to obtain the vendor patch. As a compensating control, restrict write access to the MailEnable installation directory to only trusted administrators until the patch is applied.

Recommended fix High confidence

10.54

  1. 1. Back up the current MailEnable installation and configuration data before proceeding with the upgrade.
  2. 2. Download MailEnable version 10.54 (or the latest stable version) from the official MailEnable website (www.mailenable.com).
  3. 3. Run the MailEnable installer and follow the upgrade prompts to update the installation to version 10.54.
  4. 4. After installation completes, verify that the version is correctly reported as 10.54 or higher by checking the MailEnable administrative interface or installed program information.
  5. 5. Restart the MailEnable services to ensure the new executable and DLLs are properly loaded.
