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
In Sophos Web Appliance (SWA) before 4.3.1.2, a section of the machine's configuration utilities for adding (and detecting) Active Directory servers was vulnerable to remote command injection, aka NSWA-1314.

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

Remote command injection vulnerability in Sophos Web Appliance's Active Directory server configuration utilities. An authenticated attacker with access to the AD configuration section could inject arbitrary OS commands through unsanitized input parameters, leading to complete system compromise.

MitigationUpgrade Sophos Web Appliance to version 4.3.1.2 or later. If immediate patching is not feasible, limit administrative interface access to trusted IP addresses and monitor for anomalous AD server configuration attempts.

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 Sophos Web Appliance installation
    Check the product name displayed in the web interface header or check system documentation/inventory for Sophos Web Appliance deployment
    Affected if The target is not Sophos Web Appliance, this CVE does not apply
  2. Determine installed version
    Locate the version number in the Sophos Web Appliance admin interface (typically under System > Maintenance > Version) or check via CLI if available
    Affected if Installed version is 4.3.1.1 or earlier, placing it within the affected range
  3. Verify Active Directory integration is configured
    Check if the appliance has Active Directory server configuration enabled under the directory services or AD configuration section of the admin interface
    Affected if AD integration is not configured, the specific attack vector is not present; however, the vulnerable code may still exist in the installation
  4. Confirm access to AD configuration interface
    Review user accounts and their permissions to determine if any accounts have access to the AD server configuration utilities section
    Affected if Untrusted or compromised accounts have access to AD configuration, an authenticated attacker could exploit the injection flaw

Environment is affected if running Sophos Web Appliance version 4.3.1.1 or earlier with Active Directory integration enabled and accessible to untrusted users.

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 4.3.1.1
Interim mitigation

Upgrade Sophos Web Appliance to version 4.3.1.2 or later. If immediate patching is not feasible, limit administrative interface access to trusted IP addresses and monitor for anomalous AD server configuration attempts.
