National Security Agency Cybersecurity Advisory: Mitigating Recent VPN Vulnerabilities (October 7,2019)

Multiple Nation State Advanced Persistent Threat (APT) actors have weaponized CVE-2019-11510, CVE-2019-11539, and CVE-2018-13379 to gain access to vulnerable VPN devices.

In August, 2019, the Canadian Centre for Cyber Security released guidance for mitigating vulnerabilities in 3 major VPN products (Pulse Secure®, Palo Alto GlobalProtect™, and Fortinet Fortigate®). That guidance lists indicators of compromise for detecting malicious activity [1]. This Cybersecurity Advisory is intended to convey additional actions for compromise recovery and longer-term actions for hardening.
