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 confidenceSQL injection vulnerability in AccountStatus.jsp within the Admin Portal of Sophos XG firewall allows authenticated remote attackers to execute arbitrary SQL commands via the username GET parameter. The vulnerability stems from improper input sanitization allowing SQL commands to be injected into database queries.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Sophos XG firewall versionAccess the Admin Portal dashboard or run 'version' command in console to retrieve the installed Sophos Sfos firmware versionAffected if Installed version equals exactly 17.0.8
-
Confirm Admin Portal is accessibleVerify that the Sophos Admin Portal web interface (typically ports 443 or 4444) is reachable from your networkAffected if Admin Portal is exposed and responds to requests
-
Locate AccountStatus.jsp endpointAttempt to access /AccountStatus.jsp or similar path in the Admin Portal web directoryAffected if AccountStatus.jsp file exists and is accessible without authentication or with valid authentication
-
Verify username parameter handlingInspect HTTP requests to the Admin Portal for any use of the 'username' GET parameter in AccountStatus.jsp or related endpointsAffected if The username parameter is processed without parameterized queries or input sanitization
You are affected if your Sophos Sfos firewall is exactly version 17.0.8, the Admin Portal is accessible, and the username parameter in AccountStatus.jsp accepts unsanitized input.
Generated from the published advisory. Verify against your own configuration.
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 dataApply vendor patch or upgrade to a fixed version of Sophos XG firewall that addresses this vulnerability. If no patch available, implement input validation and parameterized queries on the username parameter.
