RXSS-10: Hidden Parameter Through JavaScript Analysis

RXSS-10 Hidden Parameter Through JavaScript Analysis Advanced Unsolved CloudPeak Telemetry

Fictional Application

CloudPeak Telemetry

Multi-Cloud Node Monitoring & Uptime

You are testing CloudPeak Telemetry, an infrastructure monitoring dashboard. The primary user interface contains no visible search or input fields. However, real-world penetration testers frequently uncover undocumented debug and diagnostic parameters by auditing client-side JavaScript assets. Discover the hidden endpoint and parameter.

🎯 Assessment Objective

Inspect the application's loaded JavaScript assets, locate the hidden diagnostic endpoint/parameter, and achieve XSS.

Educational Guidance: Treat this lab like an authorized penetration test. Analyze user-controlled parameters, review browser source code and developer tools, and discover how input is handled.
