Security readout for executives and security teams
Plain-English summary
Older Greenbone web administration components had an XSS flaw in 404 URL handling. If a user accessed a crafted missing page, script could run in that user’s browser. The strongest urgency is for internet-exposed or broadly accessible Greenbone consoles.
Executive priority
Prioritize remediation for externally reachable Greenbone consoles or environments with many operators. Treat as lower urgency where access is tightly restricted and versions are already fixed.
Technical view
CVE-2019-25047 affects Greenbone Security Assistant before 8.0.2 and Greenbone OS before 5.0.10. The issue is cross-site scripting in gsad during 404 URL handling. Public sources do not provide CVSS, CWE, detailed impact scope, or confirmed exploitation.
Likely exposure
Organizations running GSA before 8.0.2 or GOS before 5.0.10 may be exposed, especially where the Greenbone web interface is reachable by many users or from untrusted networks.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation evidence. Practical risk likely depends on user interaction and whether attackers can get authenticated or privileged users to open crafted 404 URLs.
Researcher notes
Evidence is limited to the CVE description and Greenbone references. No CVSS vector, CWE mapping, proof-of-concept status, or exploitation telemetry is provided in the source bundle.
Mitigation direction
- Upgrade GSA to 8.0.2 or later.
- Upgrade Greenbone OS to 5.0.10 or later.
- Check Greenbone changelog and vendor guidance for deployment-specific fixes.
- Restrict Greenbone web console access to trusted networks and users.
- Review administrative interface exposure if internet reachable.
Validation and detection
- Inventory deployed GSA and GOS versions.
- Confirm gsad-backed web interfaces are not below fixed versions.
- Review web access logs for unusual 404 URL patterns.
- Verify administrative consoles are not publicly exposed unnecessarily.
- Track Greenbone issue and pull request references for fix context.
