Security readout for executives and security teams

CVE-2018-13376 is a Fortinet FortiOS information leak. Certain older FortiOS versions may return data from an uninitialized memory buffer in web proxy disclaimer pages, potentially exposing sensitive information in HTTP responses. Exposure is most likely where affected FortiOS releases are still running and web proxy disclaimer response pages are reachable by users or clients. Handle as a targeted legacy Fortinet exposure issue. It is not supported here as actively exploited, but sensitive data leakage from perimeter infrastructure warrants prompt inventory and vendor-guided remediation. Mitigation focus: Inventory FortiOS versions and identify systems in the affected ranges.; Review Fortinet advisory FG-IR-18-325 for vendor-approved fixed versions or remediation.; Prioritize affected systems whose web proxy disclaimer pages are externally or broadly reachable..
