Threat Actors Chained Vulnerabilities in Ivanti

Vulnerability

January 22, 2025

The Cybersecurity and Infrastructure Security Agency (CISA) and Federal Bureau of Investigation (FBI) are releasing this Joint Cybersecurity Advisory in response to exploitation in September 2024 of vulnerabilities in Ivanti Cloud Service Appliances (CSA): CVE-2024-8963, an administrative bypass vulnerability; CVE-2024-9379, a SQL injection vulnerability; and CVE-2024-8190 and CVE-2024-9380, remote code execution vulnerabilities.

Note: The CVEs in this advisory are unrelated to vulnerabilities in Ivanti’s Connect Secure, Policy Secure, and ZTA Gateways. For more information on mitigating CVE-2025-0282 and CVE-2025-0283, see Ivanti Releases Security Updates for Connect Secure, Policy Secure, and ZTA Gateways.
According to CISA and trusted third-party incident response data, threat actors chained the listed vulnerabilities to gain initial access, conduct remote code execution (RCE), obtain credentials, and implant webshells on victim networks. The threat actors’ primary exploit paths were two vulnerability chains. One exploit chain leveraged CVE-2024-8963 in conjunction with CVE-2024-8190 and CVE-2024-9380 and the other chain exploited CVE-2024-8963 and CVE-2024-9379. In one confirmed compromise, the threat actors moved laterally to two servers.
All four vulnerabilities affect Ivanti CSA version 4.6x versions before 519, and two of the vulnerabilities (CVE-2024-9379 and CVE-2024-9380) affect CSA versions 5.0.1 and below. According to Ivanti, these CVEs have not been exploited in version 5.0.
Ivanti CSA 4.6 is End-of-Life (EOL) and no longer receives patches or third-party libraries. CISA and FBI strongly encourage network administrators to upgrade to the latest supported version of Ivanti CSA. Network defenders are encouraged to hunt for malicious activity on their networks using the detection methods and indicators of compromise (IOCs) within this advisory. Credentials and sensitive data stored within the affected Ivanti appliances should be considered compromised. Organizations should collect and analyze logs and artifacts for malicious activity and apply the incident response recommendations within this advisory.
