CVE-2020-12828

Estado: ModificadaCrítica (9.8)—

An issue was discovered in AnchorFree VPN SDK before 1.3.3.218. The VPN SDK service takes certain executable locations over a socket bound to localhost. Binding to the socket and providing a path where a malicious executable file resides leads to executing the malicious executable file with SYSTEM privileges.
