Code execution via crafted CLI command overflow
Published Jun 11, 2024 · Updated Aug 27, 2025
Stack-based buffer overflow in Fortinet FortiOS allows local users with CLI access to execute unauthorized code via crafted commands. The CLI command-processing path writes attacker-controlled command data beyond a stack buffer; Fortinet has not disclosed the specific command or function. Fortinet rates exploitation as local with high privileges, and successful exploitation grants code or command execution in the FortiOS context.
