Ivanti CSA Exploit Chain: Auth Bypass + SQLi/Command Injection to Webshell

A suspected nation-state operator chained four Ivanti Cloud Services Appliance zero-days against an internet-facing appliance: an unauthenticated path-traversal auth bypass, command injection in the date/time and reporting handlers for root-level execution, PHP webshells for persistence, theft of the appliance administrator password and root SSH key, and a SQL-injection pivot to a backend SQL Server via xp_cmdshell. Reconstruct the full chain from SIEM, endpoint XDR, and perimeter firewall telemetry, and classify the key techniques.
