CWE-458: DEPRECATED: Incorrect Initialization

What is DEPRECATED: Incorrect Initialization?

• Overview: CWE-458, now deprecated, referred to incorrect initialization of variables or data structures, which could lead to undefined behavior or security vulnerabilities. This weakness was deprecated because it overlapped with CWE-454 and the name suggested a broader issue. Developers should refer to CWE-665 for general initialization problems.

• Exploitation Methods:

• Attackers might exploit incorrect initialization to inject malicious data or manipulate program flow.
• Common techniques include exploiting uninitialized variables to gain unauthorized access or cause program crashes.

• Security Impact:

• Direct consequences include unpredictable program behavior and potential for code execution vulnerabilities.
• Cascading effects may involve data corruption, crashes, or security bypasses.
• Business impact could involve data breaches, loss of customer trust, and legal implications.

• Prevention Guidelines:

• Ensure all variables and data structures are properly initialized before use.
• Follow coding standards and guidelines that emphasize initialization best practices.
• Use static analysis tools to identify potential uninitialized variables or data structures.
