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
Windu CMS is vulnerable to User Enumeration. This issue occurs during logon, where a difference in messages could allow an attacker to determine if the login is valid or not, enabling a brute force attack with valid logins. Only version 4.1 was tested and confirmed as vulnerable. This issue was fixed in version 4.1 build 2250.

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

Windu CMS 4.1 is vulnerable to user enumeration during the login process. The application returns different responses or error messages for valid versus invalid usernames, allowing unauthenticated attackers to discover valid user accounts in the system through simple probing. This information can then be used to focus brute-force attacks on valid accounts.

MitigationUpgrade Windu CMS to version 4.1 build 2250 or later, which contains the fix for this user enumeration vulnerability.

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. Confirm Windu CMS version
    Access the admin panel, footer, or system information page to identify the installed version number. Compare against version 4.1.
    Affected if The installed version is exactly 4.1 (or a build earlier than 2250 if build number is visible)
  2. Locate the login page
    Navigate to the login endpoint (typically /admin or /login) on the Windu CMS installation.
    Affected if The login page is accessible without authentication
  3. Test error message for invalid username
    Submit a login attempt with a clearly invalid/random username that does not exist in the system. Note the exact error message returned.
    Affected if An error message is returned (such as 'user not found' or 'invalid username')
  4. Test error message for valid username
    Submit a login attempt with a valid username (if known) but incorrect password. Note the exact error message returned and compare to step 3.
    Affected if The error message for valid username differs from the invalid username case (e.g., 'invalid password' vs 'user not found')
  5. Check for timing differences
    Observe if response times differ between valid and invalid username attempts, or if the application behaves differently in other measurable ways.
    Affected if The application responds differently (timing, message content, or behavior) based on username validity

If running Windu CMS version 4.1 and the login page returns distinguishable messages for valid versus invalid usernames, the environment is affected by this user enumeration vulnerability.

Mitigation

Upgrade Windu CMS to version 4.1 build 2250 or later, which contains the fix for this user enumeration vulnerability.

Recommended fix Moderate confidence

Windu CMS version 4.1 build 2250

  1. Obtain Windu CMS version 4.1 build 2250 from the official vendor (windu.org) or your existing update channel
  2. Backup your current Windu CMS installation and database before proceeding
  3. Replace the existing Windu CMS files with the new version 4.1 build 2250 files
  4. Verify the installation by attempting to log in with test accounts
  5. Confirm the login messages no longer differ between valid and invalid usernames (both should return the same error message)
