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
The web framework in IronPort AsyncOS on Cisco Web Security Appliance devices before 7.1.3-013, 7.5 before 7.5.0-838, and 7.7 before 7.7.0-550 allows remote authenticated users to execute arbitrary commands via crafted command-line input in a URL sent over IPv4, aka Bug ID CSCzv69294.

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 the device as Cisco Web Security Appliance or IronPort AsyncOS
    Run 'version' or 'show version' command in the CLI to confirm the appliance type and model
    Affected if The device is not a Cisco Web Security Appliance or IronPort AsyncOS device (not affected)
  2. Determine the installed AsyncOS version
    Execute 'version' in the appliance CLI and note the full version string (e.g., 7.1.3, 7.5.0, 7.7.0-445)
    Affected if Version is 7.1.3 or lower, or 7.5.x (any minor release), or 7.7.x (any minor release)
  3. Verify the web interface is enabled
    Check web interface status via 'techsupport' dump or examine the HTTP/HTTPS service listening on ports 8080/8443 using 'netstat' or 'show ports' CLI command
    Affected if The web interface is disabled (the vulnerability requires the web framework to be active)
  4. Confirm IPv4 interface is configured
    Run 'interfaceconfig' or 'show interface' in the CLI to verify IPv4 is enabled on an active interface
    Affected if IPv4 is not configured and only IPv6 is in use (the vulnerability specifically targets IPv4)
  5. Compare version against patch releases
    If version appears to be 7.1.3, 7.5.0, or 7.7.0, check if the build number is -013, -838, -550 or higher respectively (e.g., 7.7.0-550)
    Affected if Build number is below 7.1.3-013, 7.5.0-838, or 7.7.0-550

The system is affected if it is a Cisco Web Security Appliance running AsyncOS version 7.1.3 or lower, 7.5.x, or 7.7.x with the web interface enabled and IPv4 configured.

Upgrade available Upgrade to a release after 7.1.3
Interim mitigation

Upgrade Cisco Web Security Appliance to version 7.1.3-013, 7.5.0-838, 7.7.0-550 or later to patch the vulnerable web framework component.

Recommended fix High confidence

Upgrade to AsyncOS 7.1.3-013, 7.5.0-838, or 7.7.0-550 (whichever is the appropriate upgrade path for your current branch)

  1. 1. Identify the current AsyncOS version by accessing the WSA CLI and running the 'version' command
  2. 2. Download the appropriate patched AsyncOS image from Cisco (7.1.3-013 for 7.1.x, 7.5.0-838 for 7.5.x, or 7.7.0-550 for 7.7.x) from the Cisco Software Download center
  3. 3. Upload the patch file to the WSA via the web interface (System Administration > Upgrade) or CLI using 'loadconfig' or equivalent
  4. 4. Initiate the upgrade via System Administration > Upgrade in the web GUI or 'upgrade' command in CLI
  5. 5. After upgrade completes, verify the new version matches the expected patched release (e.g., 7.7.0-550)
  6. 6. Validate that the web interface is accessible and the WSA is functioning normally
