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
Multiple SQLi vulnerabilities in Webadmin allow for privilege escalation from admin to super-admin in Sophos Firewall older than version 18.5 MR4 and version 19.0 MR1.

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

Multiple SQL injection vulnerabilities in the Webadmin interface of Sophos Firewall allow an authenticated administrator to escalate privileges to super-admin by injecting malicious SQL queries, exploiting insufficient input validation in database queries.

MitigationUpgrade Sophos Firewall to version 18.5 MR4 or later, or version 19.0 MR1 or later. If immediate patching is not possible, restrict Webadmin access to trusted admin IPs only via firewall rules.

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. Determine Sophos Firewall version
    Access the Webadmin interface and navigate to System > Backup & Firmware, or run 'version' command in the console to retrieve the installed firmware version.
    Affected if Version is 18.5, 19.0, or any version below 18.5
  2. Verify Webadmin interface is enabled
    In Webadmin, go to Administration > Device Access, or inspect the configuration for enabled admin interfaces. Confirm Webadmin/HTTPS admin access is permitted.
    Affected if Webadmin interface is enabled and accessible on any IP
  3. Confirm admin account privileges
    Navigate to Authentication > Administrators in Webadmin. Review the list of administrator accounts and their assigned privilege levels. Look for any accounts with Super Admin role that were not intentionally created.
    Affected if Unexpected or unauthorized Super Admin accounts exist in the administrator list
  4. Review admin activity logs for SQL injection indicators
    In Webadmin, go to Logs & Monitoring > Admin Logs, or check system log files for entries containing unusual SQL syntax, UNION SELECT statements, or comment sequences (--) in admin actions.
    Affected if Logs contain SQL-like query fragments or suspicious admin actions from standard user accounts

The environment is affected if the Sophos Firewall version is 18.5, 19.0, or below 18.5 AND the Webadmin interface is accessible to authenticated administrators.

Upgrade available Upgrade to 18.5 or later
Fixed in 18.5
Interim mitigation

Upgrade Sophos Firewall to version 18.5 MR4 or later, or version 19.0 MR1 or later. If immediate patching is not possible, restrict Webadmin access to trusted admin IPs only via firewall rules.

Recommended fix High confidence

Sophos Firewall version 18.5 MR4 or 19.0 MR1 (or latest stable release)

  1. Obtain the fixed Sophos Firewall version (18.5 MR4 or later, or 19.0 MR1 or later) from the Sophos support portal
  2. Review Sophos upgrade documentation for your specific deployment model (hardware, virtual, or software)
  3. Back up the current firewall configuration before proceeding
  4. Access the Webadmin interface or use the console/CLI to upload and install the updated firmware
  5. Complete the upgrade process following Sophos recommended procedures
  6. Verify the new version is installed and the SQL injection vulnerability is remediated
Caveat Review Sophos release notes for any configuration changes or compatibility considerations before upgrading
