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
BigFix WebUI non-master operators are missing controls that prevent them from being able to modify the relevance of fixlets or to deploy fixlets from the BES Support external site.

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 · moderate confidence

This is an authorization bypass vulnerability in BigFix WebUI where non-master operators (limited privilege users) can modify the relevance of fixlets and deploy fixlets from the BES Support external site. These actions should require master operator privileges, but missing access controls allow lower-privileged users to perform these sensitive operations.

MitigationImplement proper authorization checks to restrict non-master operators from modifying fixlet relevance and from deploying fixlets from external sites. Configure role-based access controls to enforce privilege separation.

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 BigFix WebUI installation and version
    Check if HCL BigFix WebUI version 20 is installed in your environment. Access the WebUI interface or check the installed software inventory for 'BigFix WebUI' version 20.
    Affected if BigFix WebUI version 20 is installed and running.
  2. Identify non-master operator accounts
    Review the user accounts configured in BigFix WebUI and check their assigned roles. Look for users that are NOT assigned the 'Master Operator' role.
    Affected if There are user accounts in BigFix WebUI with roles other than Master Operator.
  3. Verify WebUI access for limited privilege users
    Log in to BigFix WebUI using a non-master operator account and attempt to access fixlet management features. Check if the WebUI accepts connections from these lower-privileged accounts.
    Affected if Non-master operator accounts can successfully authenticate to the BigFix WebUI interface.
  4. Check fixlet relevance modification capability
    Using a non-master operator account, attempt to modify the relevance of any fixlet within the WebUI interface. Verify if the modification option is available and functional for non-privileged users.
    Affected if Non-master operators can modify fixlet relevance through the WebUI.
  5. Check external site deployment capability
    Using a non-master operator account, attempt to deploy or import fixlets from the BES Support external site or any external fixlet site through the WebUI.
    Affected if Non-master operators can deploy fixlets from external sites through the WebUI.

Your environment is affected if BigFix WebUI version 20 is running and non-master operator accounts can modify fixlet relevance or deploy fixlets from external sites through the WebUI.
