CVE-2024-21887Known exploitationPublic exploitNetwork attack vector

Appliance command execution via unsanitized node name

Published Jan 12, 2024 · Updated Aug 4, 2026

Command injection in Ivanti Connect Secure and Policy Secure 9.x and 22.x allows remote authenticated users to execute appliance commands. The license keys-status web endpoint accepts a node-name path value and processes embedded shell syntax as an operating-system command. Administrative access is required in isolation; chaining an authentication bypass removes that gate and yields appliance-level command execution.
