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
Multiple cross-site request forgery (CSRF) vulnerabilities in the administrative interface in Bloxx Web Filtering before 5.0.14 allow remote attackers to hijack the authentication of administrators for requests that perform administrative actions.

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

This is a CSRF (Cross-Site Request Forgery) vulnerability in the administrative web interface of Bloxx Web Filtering versions prior to 5.0.14. The vulnerability allows remote attackers to trick authenticated administrators into performing unintended administrative actions by crafting malicious requests that the victim's browser automatically submits due to lack of proper CSRF protection tokens.

MitigationImplement anti-CSRF tokens (synchronizer token pattern) on all administrative forms and validate the CSRF token on every state-changing POST request. Additionally, enable SameSite cookie attributes and validate the Referer header as defense-in-depth.

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 Bloxx Web Filtering installation
    Locate the Bloxx Web Filtering application or appliance in your environment. Check system documentation, installed software lists, or network inventory for Bloxx Web Filtering devices. Note the hostname or IP address of the filtering appliance.
    Affected if Bloxx Web Filtering is not found in your environment, you are not affected.
  2. Determine installed version
    Access the administrative web interface of the Bloxx device (typically via HTTPS on port 443 or 8080). Log in as an administrator and navigate to the system information, about, or status page to find the exact version number. Alternatively, check the appliance's command-line interface or system files for the version.
    Affected if The version is 5.0.13 or lower, indicating a vulnerable version.
  3. Verify version is within affected range
    Compare your identified version against the affected range: versions prior to 5.0.14 (specifically <= 5.0.13). Record whether your version falls within this range.
    Affected if Your installed version is 5.0.13 or any version lower than 5.0.14.
  4. Confirm administrative web interface is accessible
    Determine if the Bloxx administrative web interface is reachable on your network. Check if TCP ports used for admin access (commonly 443, 8443, or 8080) are open and accessible from network segments where users operate.
    Affected if The admin interface is exposed and the version is <= 5.0.13, you are affected by this CSRF vulnerability.

You are affected if Bloxx Web Filtering version 5.0.13 or lower is installed and its administrative web interface is accessible, as these versions lack CSRF token protection on administrative forms.

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 5.0.13
Interim mitigation

Implement anti-CSRF tokens (synchronizer token pattern) on all administrative forms and validate the CSRF token on every state-changing POST request. Additionally, enable SameSite cookie attributes and validate the Referer header as defense-in-depth.
