Logic Flaw Identification: State Desynchronization

Research Focus: State management vulnerabilities in distributed systems

Overview: Researched state desynchronization vulnerabilities where client-side and server-side state diverge, leading to authorization bypasses and unintended access.

Methodology:

• Mapped state transitions across multi-step workflows
• Identified critical decision points dependent on state
• Tested edge cases: network interruptions, concurrent requests, malformed state data
• Developed proof-of-concept exploits demonstrating impact

Example Vulnerability: Multi-step checkout flow allowing price manipulation through state manipulation between steps.

Impact: Unauthorized access to restricted functionality, data integrity violations, business logic bypass.
