CWE-666: Operation on Resource in Wrong Phase of Lifetime
Learn about CWE-666 (Operation on Resource in Wrong Phase of Lifetime), its security impact, exploitation methods, and prevention guidelines.
What is Operation on Resource in Wrong Phase of Lifetime?
• Overview: Operation on Resource in Wrong Phase of Lifetime (CWE-666) occurs when software performs actions on a resource at an inappropriate point in its lifecycle. This can lead to unintended and potentially harmful behavior, such as using a resource before it's fully initialized or after it's been released.
• Exploitation Methods:
- Attackers can exploit this vulnerability by manipulating program flow to access resources in invalid states.
- Common attack patterns include race conditions and improper state management.
• Security Impact:
- Direct consequences include application crashes, data corruption, and unexpected behavior.
- Potential cascading effects could involve security breaches or data leaks.
- Business impact may result in service downtime, loss of customer trust, and potential legal liabilities.
• Prevention Guidelines:
- Specific code-level fixes include checking resource states before performing operations and ensuring proper initialization and cleanup routines.
- Security best practices involve proper resource lifecycle management and validation of resource states.
- Recommended tools and frameworks are static analysis tools to detect improper resource usage and employing resource management libraries that enforce lifecycle rules.
