March 11, 2019Mohit Kumar
A security researcher has discovered a severe vulnerability in the popular, open source event-driven platform StackStorm that could allow remote attackers to trick developers into unknowingly execute arbitrary commands on targeted services. StackStorm, aka "IFTTT for Ops," is a powerful event-driven automation tool for integration and automation across services and tools that allows developers to configure actions, workflows, and scheduled tasks, in order to perform some operations on large-scale servers. For example, you can set instructions (if this, then that) on Stackstorm platform to automatically upload network packet files to a cloud-based network analyze service, like CloudShark, in events when your security software detects an intrusion or malicious activity in the network. Since StackStorm executes actions—which can be anything, from the HTTP request to an arbitrary command—on remote servers or services that developers integrate for automated tasks, the pl
