What problem does it solve?
This Skill eliminates the gap in standard reconnaissance for legacy ASP.NET applications (including Webforms, WCF, SharePoint farms, and Telerik-integrated sites) by identifying high-severity vulnerability primitives such as ViewState deserialization flaws, exposed diagnostic endpoints, and framework-specific bypasses that are frequently missed by automated scanning tools.
Core Features & Use Cases
- ASP.NET Surface Fingerprinting: Identifies framework versions, IIS configurations, and ASP.NET-specific components via response headers, hidden form fields, and URL patterns to narrow the attack scope without manual guesswork.
- High-Value Primitive Detection: Probes for signed-only ViewState, dual-parser MAC bypass anti-patterns, anonymously accessible trace.axd/elmah.axd endpoints, and unpatched Telerik/SharePoint deserialization chains that can lead to RCE or credential disclosure.
- Real-World Use Case: A pentester assessing an enterprise banking portal built on classic ASP.NET Webforms can use this Skill to quickly confirm if ViewState is signed-only, check for exposed ELMAH logs containing sensitive stack traces, and identify unauthenticated WCF admin endpoints with weaker access controls than the main application.
Quick Start
Use the hunt-aspnet skill to scan the target ASP.NET application at https://target.example for exploitable ViewState misconfigurations, exposed diagnostic endpoints, and Telerik component vulnerabilities, then prioritize findings for your pentest report.
