CVE-2016-8347
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 · uneditedAn issue was discovered in Kabona AB WebDatorCentral (WDC) application prior to Version 3.4.0. WDC does not limit authentication attempts that may allow a brute force attack method.
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 confidenceThe WebDatorCentral (WDC) application prior to version 3.4.0 fails to implement rate limiting, account lockout, or CAPTCHA mechanisms on the authentication endpoint, allowing remote attackers to perform unlimited login attempts and conduct brute force attacks to compromise user credentials.

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 if WebDatorCentral is installedLocate the Kabona Ab WebDatorCentral application in your environment. Check for installation directories, services, or web applications running WDC.Affected if WebDatorCentral is found installed in the environment
-
Determine the installed versionCheck the version of the installed WebDatorCentral application. Consult application documentation or check version information in the installation directory, configuration files, or application metadata.Affected if The version is lower than 3.4.0 or the version cannot be determined (all versions prior to 3.4.0 are affected)
-
Inspect authentication endpoint configurationExamine the WebDatorCentral login endpoint configuration. Check for rate limiting rules in the web server (e.g., nginx, Apache) or application-level rate limiting settings.Affected if No rate limiting is configured on the authentication endpoint (login page)
-
Verify account lockout policy settingsReview user account security settings in WDC. Look for account lockout or account disabling configuration after failed login attempts.Affected if Account lockout after failed attempts is disabled or not configured
-
Check for CAPTCHA or similar brute force protectionInspect the login page and authentication flow for CAPTCHA, challenge-response, or similar mechanisms designed to prevent automated login attempts.Affected if No CAPTCHA or equivalent protection is present on the login form
The environment is affected if WebDatorCentral version lower than 3.4.0 is installed AND the authentication endpoint lacks rate limiting, account lockout, and CAPTCHA protections.

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 · scopedImplement authentication attempt limiting with account lockout policies after a configurable number of failed attempts, combined with rate limiting on the login endpoint to throttle repeated requests from the same source.
Version 3.4.0
- Obtain WebDatorCentral Version 3.4.0 from the vendor (Kabona AB)
- Create a complete backup of the current WDC installation and database
- Install Version 3.4.0 in a staging environment to verify functionality
- Deploy Version 3.4.0 to production
- Verify that authentication attempts are now properly rate-limited to prevent brute force attacks
