Lifecycle Timeline
2DescriptionNVD
A server-side request forgery vulnerability in the SAML component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure (9.x, 22.x) and Ivanti Neurons for ZTA allows an attacker to access certain restricted resources without authentication.
Executive ViewAI
CVE-2024-21893 presents notable security risk, a server-side request forgery vulnerability rated CVSS 8.2. Attackers could trick authenticated users into performing unintended actions, potentially modifying critical settings or data. This vulnerability is actively exploited in the wild (KEV-listed) and requires immediate remediation. Immediate patching is required per CISA KEV mandate.
Apply vendor patch. If immediate patching is not feasible: (1) Implement strict egress filtering; (2) Use allowlists for outbound connections; (3) Block access to cloud metadata endpoints.
