The vulnerability stems from improper neutralization of special elements used in SQL commands. According to Fortinet, an attacker with low privileges could exploit this vulnerability to execute unauthorized code or commands. While the exact attack vector is not detailed in the provided source material, successful exploitation would allow for arbitrary code execution within the context of the FortiDDoS-F appliance. This is a high-severity vulnerability because it could lead to complete system compromise.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker authenticates to the FortiDDoS-F appliance with valid low-privilege credentials.\u003c/li\u003e\n\u003cli\u003eAttacker crafts a malicious SQL query containing special characters designed to exploit the SQL injection vulnerability.\u003c/li\u003e\n\u003cli\u003eAttacker sends the crafted SQL query to the vulnerable FortiDDoS-F endpoint.
