Authenticated code execution via unchecked buffer copy
Published Mar 31, 2025 · Updated Mar 31, 2025
Classic buffer overflow in affected Fortinet FortiMail and FortiNDR versions allows remote authenticated users to run code via crafted HTTP requests. The webmail and administrative HTTP request handlers copy attacker-controlled input into a fixed-size buffer without verifying its length. Regular FortiMail webmail access or FortiNDR administrative access is required; successful exploitation runs code in the affected service context.
