Uncontrolled Recursion in .NET Denial of Service

Executive Summary

This vulnerability involves uncontrolled recursion in .NET, where an attacker can trigger excessive recursive calls to consume system resources. This leads to a denial of service (DoS) condition over a network, making services unavailable.

Detection Guidance

Detecting uncontrolled recursion in .NET may require monitoring for excessive stack usage or abnormal recursion patterns. Check application logs for stack overflow errors or high CPU usage in .NET processes. Use performance monitoring tools like PerfView or Windows Performance Monitor to track recursion depth and stack exhaustion events.
