The Federal Bureau of Investigation (FBI) and CISA have released a Joint Cybersecurity Advisory (CSA) to warn users and administrators of the likelihood that advanced persistent threat (APT) actors are actively exploiting known Fortinet FortiOS vulnerabilities CVE-2018-13379, CVE-2020-12812, and CVE-2019-5591. APT actors may use these vulnerabilities or other common exploitation techniques to gain initial access to multiple government, commercial, and technology services. Gaining initial access pre-positions the APT actors to conduct future attacks.

CISA encourages users and administrators to review Joint CSA AA21-092A: APT Actors Exploit Vulnerabilities to Gain Initial Access for Future Attacks and implement the recommended mitigations.
