CVE-2025-20281: Cisco ISE API Unauthenticated Remote Code Execution Vulnerability

This excerpt analyzes a command-injection issue in Cisco ISE's configureStrongSwan.sh: the IKE_ID value comes from a script argument and, due to how Java 8's Runtime.exec() tokenizes command arguments differently from bash, quoted payloads can be split and enable injection attempts (example payloads shown include variants of 'x; touch /flag'); the author inspects OpenJDK exec() behavior to properly craft an exploit.
