Alert


CISA, FBI, AND CNMF RELEASE ADVISORY ON MULTIPLE NATION-STATE THREAT ACTORS
EXPLOIT CVE-2022-47966 AND CVE-2022-42475

Release Date
September 07, 2023


Today, CISA, Federal Bureau of Investigation (FBI), and U.S. Cyber Command’s
Cyber National Mission Force (CNMF) published a joint Cybersecurity Advisory
(CSA), Multiple Nation-State Threat Actors Exploit CVE-2022-47966 and
CVE-2022-42475. This CSA provides information on an incident at an Aeronautical
Sector organization, with malicious activity occurring as early as January
2023. 

CISA, FBI, and CNMF confirmed that nation-state advanced persistent threat (APT)
actors exploited CVE-2022-47966 to gain unauthorized access to a public-facing
application (Zoho ManageEngine ServiceDesk Plus), establish persistence, and
move laterally through the network. This vulnerability allows for remote code
execution on the ManageEngine application. Additional APT actors were also
observed exploiting CVE-2022-42475 to establish presence on the organization’s
firewall device.

The authoring agencies urge organizations to review this CSA and implement the
recommended mitigations, which align with CISA’s Cross-Sector Cybersecurity
Performance Goals (CPGs)—developed by CISA and the National Institute of
Standards and Technology (NIST)—as well as NSA-recommended best practices for
securing infrastructure.

All organizations should report suspicious or criminal activity related to
information found in this joint Cybersecurity Advisory by contacting your local
FBI field office and CISA’s 24/7 Operations Center at report@cisa.gov(link sends
email) or (888) 282-0870.
