CVE-2024-33505Network attack vector

Unauthenticated privilege escalation via crafted HTTP requests

Published Nov 12, 2024 · Updated Nov 12, 2024

Heap-based buffer overflow in Fortinet FortiManager and FortiAnalyzer allows remote attackers to escalate privileges via crafted HTTP requests. The products mishandle attacker-controlled HTTP request data in an undisclosed heap buffer, causing an out-of-bounds write. No authentication or user interaction is required, but Fortinet rates exploitation as high complexity; successful exploitation affects confidentiality, integrity, and availability.
