Privileged code execution via crafted HTTP commands
Published Mar 11, 2025 · Updated Feb 26, 2026
Format-string injection in Fortinet appliances allows remote authenticated users to execute code through crafted HTTP or HTTPS commands. The issue affects FortiOS, FortiProxy, FortiPAM, FortiSRA, and FortiWeb; Fortinet identifies externally controlled format-string processing but does not disclose the responsible handler or function. A privileged account and network access to the affected interface are required, and successful exploitation executes unauthorized code or commands on the appliance.
