Name of the Vulnerable Software and Affected Versions Fortinet FortiOS versions prior to 7.0.3

Description A stack-based buffer overflow vulnerability in Fortinet FortiOS allows a privileged attacker to execute arbitrary code via specially crafted CLI commands, provided the attacker were able to evade FortiOS stack protections.
