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
Incorrect access control in the install directory (C:\Wamp64) of Wamp v3.2.6 and below allows authenticated attackers to execute arbitrary code via overwriting binaries located in the directory.

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

WampServer v3.2.6 and below has incorrect file system access controls on its installation directory (C:\Wamp64). Authenticated users with standard privileges can overwrite executable binaries in this directory, leading to arbitrary code execution with the privileges of the Wamp service or when the binaries are next invoked.

MitigationRestrict write permissions on the Wamp installation directory to only trusted administrators; remove world/group write access and ensure the Wamp service runs with minimal required privileges. Audit directory permissions and remove any unnecessary write access.

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. Verify WampServer installation exists
    Check if the C:\Wamp64 directory exists, or search for WampServer installation in common locations like C:\wamp64, C:\wamp, or the installation path specified during setup. Use 'dir C:\Wamp64' in Command Prompt or File Explorer.
    Affected if The C:\Wamp64 directory exists on the system (indicating WampServer is installed)
  2. Determine installed WampServer version
    Locate the wampmanager.exe file in the WampServer installation directory (e.g., C:\Wamp64\wampmanager.exe). Right-click the file, select Properties, and check the Details tab for the version number. Alternatively, look for a version file in the installation directory.
    Affected if The version number is 3.2.6 or lower, or if version information cannot be obtained but WampServer is present
  3. Examine write permissions on the Wamp installation directory
    Right-click the WampServer installation folder (e.g., C:\Wamp64), select Properties, go to the Security tab, and review the permissions for Users, Everyone, and other standard user groups. Check if any non-admin accounts or groups have Write or Modify permissions.
    Affected if Standard users (non-admin accounts) or the Users group have Write or Modify permissions on the C:\Wamp64 directory
  4. Verify executable binaries are world-writable
    Check specific executable files in the installation directory (such as wampmanager.exe, apache/bin/*.exe, or php/*.exe) by viewing their security permissions. Confirm if users with standard privileges can modify these files.
    Affected if Users with standard (non-elevated) privileges can overwrite executable binaries in the WampServer installation directory
  5. Check WampService account privileges
    Open Services (services.msc), locate the Wampapache or Wampmysqld services, right-click and select Properties. Note the account under which the service runs (often LocalSystem or a specific user account).
    Affected if The WampServer services run with elevated privileges (such as LocalSystem or Administrator) and the directory permissions allow standard users to write files

A user is affected if WampServer version 3.2.6 or lower is installed AND the installation directory grants Write or Modify permissions to standard (non-admin) users, allowing them to replace executable binaries.

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.

From vendor data
Upgrade available Upgrade to a release after 3.2.6
Interim mitigation

Restrict write permissions on the Wamp installation directory to only trusted administrators; remove world/group write access and ensure the Wamp service runs with minimal required privileges. Audit directory permissions and remove any unnecessary write access.
