A10:2025 - Mishandling of Exceptional Conditions
Weaknesses in how applications manage and recover from errors or unexpected states.
Intent & Description
'
🎯 Intent
Handle errors and exceptional conditions gracefully without exposing sensitive information or creating security vulnerabilities.
📋 Context
Applications that improperly handle errors may leak stack traces, database queries, or other sensitive information. Poor error handling can also leave systems in an insecure state or cause denial of service.
💡 Solution
Implement consistent error handling across the application. Never expose stack traces or internal details to users. Use generic error messages. Ensure the application fails securely. Test error handling paths thoroughly.'
Real-world Use Case
Use when designing error handling strategies, implementing exception handling, or building resilient systems.
📌 TL;DR
Handle errors gracefully and securely. Never leak internal details, fail securely, and test all error paths.
Advantages
- Prevents information leakage
- Ensures fail-secure behavior
- Improves application resilience
- Reduces attack surface
Disadvantages
- Generic errors make debugging harder
- Comprehensive error handling adds code complexity
- Testing all error paths is challenging
