Security readout for executives and security teams

This is a cross-site scripting issue in Fortinet FortiOS. An attacker could supply a malicious Host header in HTTP requests and cause arbitrary script or HTML injection. The provided sources identify affected FortiOS versions but do not include CVSS scoring, observed exploitation, or fixed-version details. Exposure is likely limited to organizations still running the listed FortiOS versions. Systems on unsupported legacy branches should be treated as higher operational risk because vendor support and patch availability may be constrained. Handle as a legacy Fortinet exposure cleanup item. It is not evidenced as actively exploited in the supplied sources, but affected versions are old and should not remain in production without vendor-supported remediation. Mitigation focus: Inventory FortiOS versions across all Fortinet appliances.; Review Fortinet advisory FG-IR-17-262 for vendor remediation guidance.; Upgrade affected FortiOS deployments to a vendor-supported fixed release where applicable..
