Key insight
Beyond the plain patch information, it is relevant that exploitation requires victim interaction and is therefore likely to be directed via phishing or manipulated links against VPN/endpoint clients.
Description
Fortinet has disclosed an origin validation vulnerability in its FortiClient products. Affected are FortiClientMac 7.4.0 through 7.4.7, FortiClientWindows 7.4.0 through 7.4.7 as well as 7.2.0 through 7.2.14, and FortiClientWindowsPAM in versions 7.4.7 and 7.2.14. An unauthenticated remote attacker may execute unauthorized code or commands through successful exploitation. However, exploitation requires interaction with the victim, which narrows the attack path. At the time of the report there is no indication of active exploitation in the wild.
