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
Websense Web Security and Web Filter before 7.1 Hotfix 21 do not set the secure flag for the Encrypted Session (SSL) cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session.

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

Websense Web Security and Web Filter versions before 7.1 Hotfix 21 fail to set the Secure flag on the Encrypted Session (SSL) cookie. Without this flag, the session cookie can be transmitted over insecure HTTP connections, making it vulnerable to interception via man-in-the-middle attacks.

MitigationApply Websense version 7.1 Hotfix 21 or later, which includes the fix to set the Secure flag on the SSL session cookie. Alternatively, configure the web server or application to set the Secure flag on the session cookie.

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. Check Websense product version
    Locate the installed Websense Web Security or Web Filter version in the product admin console under 'Help > About' or check the installer/log files. The version number is typically displayed in the format like 7.0.x or 7.1.x.
    Affected if The version is 7.0 or any 7.0.x release (the product is <= 7.0)
  2. Confirm if Hotfix 21 is applied
    In the Websense admin interface, navigate to 'Help > System Information' or check the hotfix/patch history to see which hotfixes have been installed. Look specifically for Hotfix 21 applied to version 7.1.
    Affected if The product is version 7.1 without Hotfix 21, or is version 7.0 without upgrading to 7.1 Hotfix 21
  3. Inspect session cookie for Secure flag
    Log into the Websense web portal over HTTPS using a browser. Open browser developer tools (F12), go to the Application/Storage tab, and locate the session cookie. Examine the cookie attributes to see if the 'Secure' flag is present.
    Affected if The session cookie does NOT have the Secure flag set, indicating it could be transmitted over insecure HTTP
  4. Verify if HTTP access is enabled
    Check the Websense configuration to see if HTTP (port 80) connections are allowed for user authentication or session management. Review the 'Protocol Configuration' or 'Service Ports' settings in the admin console.
    Affected if HTTP access is enabled and the session cookie lacks the Secure flag, the cookie could be intercepted in transit

You are affected if the installed Websense version is 7.0 or earlier, or is version 7.1 without Hotfix 21, AND the SSL session cookie is missing the Secure flag.

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 7.0
Interim mitigation

Apply Websense version 7.1 Hotfix 21 or later, which includes the fix to set the Secure flag on the SSL session cookie. Alternatively, configure the web server or application to set the Secure flag on the session cookie.
