Authenticated HTTPD crash via malformed PUT request
Published Apr 12, 2021 · Updated Oct 25, 2024
Stack-based buffer overflow in Fortinet FortiOS and FortiProxy allows remote authenticated users to crash HTTPD via a malformed PUT request. The HTTPD PUT-request handler accepts attacker-controlled malformed request data without enforcing the stack buffer's bounds. Valid credentials and network access to HTTPD are required; the documented consequence is a service crash, and Fortinet reports no successful code execution.
