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
Advanced Secure Gateway and Content Analysis, prior to 7.3.13.1 / 3.1.6.0, may be susceptible to a Command Injection vulnerability.

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

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 ASG appliance version
    Access the Sophos/Broadcom ASG web management interface and navigate to the About or System Information page to view the installed firmware version. Alternatively, log into the appliance CLI and run the command to display version information (commonly 'version' or 'show system-info').
    Affected if The displayed version is lower than 7.3.13.1 (for ASG) or the version cannot be confirmed as 7.3.13.1 or higher.
  2. Identify Content Analysis appliance version
    Access the Content Analysis web management interface and locate the version information in the About or System Status section. Alternatively, use the appliance CLI to retrieve the version.
    Affected if The displayed version is lower than 3.1.6.0 (for Content Analysis) or the version cannot be confirmed as 3.1.6.0 or higher.
  3. Verify management interface exposure
    Determine if the ASG or Content Analysis management web interface is accessible from untrusted networks. Check network configuration to see if ports 443 or 8443 (typical management ports) are exposed to the internet or untrusted VLANs.
    Affected if The management interface is accessible from external or untrusted networks and the version is within the affected range.

The environment is affected if the installed Broadcom Advanced Secure Gateway version is below 7.3.13.1 or Content Analysis version is below 3.1.6.0, and the management interface is network-accessible to potential attackers.
