CWE-1058: Invokable Control Element in Multi-Thread Context with non-Final Static Storable or Member Element

What is Invokable Control Element in Multi-Thread Context with non-Final Static Storable or Member Element?

• Overview: This vulnerability occurs when a function or method in a multi-threaded context uses a non-final static variable or member element. Such variables can be altered by multiple threads simultaneously, leading to unpredictable behavior and potential data corruption.

• Exploitation Methods:

• Attackers can exploit this by forcing the application into a state where multiple threads modify the same static variable, causing race conditions.
• Common attack patterns include inducing concurrency issues that lead to inconsistent data states or unexpected exceptions.

• Security Impact:

• Direct consequences include application crashes, data corruption, and unreliable program execution.
• Potential cascading effects involve security mechanisms being bypassed or failing due to inconsistent state management.
• Business impact includes loss of customer trust, potential data breaches, and increased maintenance costs.

• Prevention Guidelines:

• Specific code-level fixes include making static variables final or using local variables within methods to avoid shared state.
• Security best practices involve implementing proper synchronization mechanisms like locks or using thread-safe data structures.
• Recommended tools and frameworks include static code analysis tools to detect shared state issues and multi-threading frameworks that provide safe concurrency management.
