Security readout for executives and security teams
Plain-English summary
CVE-2018-1145 is a remote, unauthenticated stack buffer overflow reported in Belkin N750 F9K1103 routers running firmware 1.10.22. A crafted HTTP request to proxy.cgi can trigger the flaw. The sources do not provide CVSS, confirmed exploitation, or a named patch.
Executive priority
Prioritize remediation where affected routers protect business networks or expose management HTTP to the internet. Even without confirmed exploitation, remote unauthenticated memory corruption in an edge device can create serious operational risk.
Technical view
The issue affects the Belkin N750 DB Wi-Fi Dual-Band N+ Gigabit Router F9K1103, with firmware 1.10.22 listed as affected. The vulnerable component is proxy.cgi, reachable over HTTP. The public bundle identifies stack buffer overflow behavior but does not provide CWE, exploit maturity, or remediation details.
Likely exposure
Exposure is likely limited to organizations still operating Belkin N750 F9K1103 routers, especially where the router web interface is reachable from untrusted networks. The source bundle does not confirm broader Belkin product impact.
Exploitation context
The CVE is not listed as CISA KEV in the provided bundle, and no cited source confirms active exploitation. Public details identify the vulnerable CGI endpoint and crafted HTTP request condition, but this assessment does not include exploit procedure or payload guidance.
Researcher notes
Evidence is thin: the bundle provides affected product, firmware, endpoint, and vulnerability class, but no CVSS, CWE, patch identifier, or exploit status. Treat product and firmware matching as the main validation path.
Mitigation direction
- Inventory Belkin N750 F9K1103 routers and firmware versions.
- Check Belkin or Tenable guidance for firmware or replacement recommendations.
- Remove router administration interfaces from internet exposure.
- Restrict HTTP management access to trusted administrative networks.
- Replace affected devices if no supported update is available.
Validation and detection
- Confirm whether any F9K1103 device runs firmware 1.10.22.
- Verify external scans do not expose router HTTP management interfaces.
- Review network logs for unusual requests targeting proxy.cgi.
- Check asset records for unsupported or unmanaged Belkin routers.
