CVE-2024-26010Network attack vector

Code execution via crafted-packet stack overflow

Published Jun 11, 2024 · Updated Aug 27, 2025

Stack-based buffer overflow in Fortinet FortiOS, FortiPAM, FortiProxy, and FortiSwitch Manager allows attackers to execute code. Fortinet has not disclosed the affected component or the operation that overflows the stack buffer while processing crafted packets. Exploitation requires network access, user interaction, and high-complexity conditions; success executes unauthorized code or commands.
