Security readout for executives and security teams
Plain-English summary
Older Greenbone Security Assistant and Greenbone OS versions allowed Host Header Injection. In business terms, systems running affected versions may trust attacker-supplied hostname data in web requests, which can affect generated links or security-sensitive workflows depending on deployment context.
Executive priority
Treat as a targeted hygiene fix for security tooling, not an emergency based on available evidence. Prioritize exposed or internet-reachable Greenbone management interfaces first.
Technical view
CVE-2018-25016 affects GSA before 7.0.3 and GOS before 5.0.0. The public record describes Host Header Injection but does not provide CVSS, CWE, detailed impact, exploit conditions, or proof of active exploitation.
Likely exposure
Exposure is limited to organizations running Greenbone Security Assistant before 7.0.3 or Greenbone OS before 5.0.0, especially where the web interface is reachable by untrusted users or networks.
Exploitation context
The source bundle does not show KEV listing, public active exploitation, exploit code, or confirmed exploitation in the wild. Practical impact depends on how the application uses Host headers and how the interface is exposed.
Researcher notes
Public data is sparse: affected version bounds and vulnerability class are known, but CVSS, CWE, detailed root cause, and exploitation evidence are absent from the provided bundle.
Mitigation direction
- Inventory GSA and GOS versions across vulnerability management infrastructure.
- Upgrade GSA to 7.0.3 or later where applicable.
- Upgrade GOS to 5.0.0 or later where applicable.
- Restrict access to the Greenbone web interface while remediation is pending.
- Check Greenbone guidance for deployment-specific hardening.
Validation and detection
- Confirm no deployed GSA instance is older than 7.0.3.
- Confirm no deployed GOS instance is older than 5.0.0.
- Review exposure of the GSA web interface to untrusted networks.
- Verify reverse proxy or gateway hostname handling is explicitly configured.
- Track remediation evidence in vulnerability management records.
