What it detects
This rule detects a web application runtime spawning reconnaissance or download shell commands, the hallmark of server side template injection reaching remote code execution. Template engines such as Jinja2 or FreeMarker are abused to run os.popen against system utilities. Detecting the abnormal child process exposes exploitation of the exposed web application.
Reporting behind it
Detection content is published as a reviewed draft. Tune thresholds and exclusions against your own telemetry before enabling this rule for alerting.
