Security readout for executives and security teams

This CVE is a reflected XSS issue in Fortinet FortiOS web proxy disclaimer pages. An attacker could send a crafted URL to a user and, if the user opened it, run script or HTML in that user's browser context. The provided sources do not include a CVSS score or evidence of active exploitation. Exposure is likely limited to organizations still running the listed FortiOS versions and using affected web proxy disclaimer pages. Internet exposure is not established by the supplied sources. Treat this as a targeted cleanup item, not an emergency, unless affected FortiOS versions remain in use. The main business risk is user-session compromise through phishing-style links. Mitigation focus: Inventory FortiOS versions across all Fortinet appliances.; Review Fortinet FG-IR-17-168 for fixed versions or vendor-approved workarounds.; Prioritize upgrade or removal of the listed affected FortiOS builds..
