CWE-1107: Insufficient Isolation of Symbolic Constant Definitions

What is Insufficient Isolation of Symbolic Constant Definitions?

• Overview: This vulnerability occurs when symbolic constants in the source code are not defined in a centralized or isolated location, which can lead to maintenance difficulties and the potential introduction of security vulnerabilities.

• Exploitation Methods:

• Attackers may exploit the lack of centralized definition to confuse or mislead developers, potentially introducing errors.
• Common attack patterns include injecting or modifying constants to alter application behavior.

• Security Impact:

• Direct consequences include increased difficulty in maintaining and updating code, leading to potential security weaknesses.
• Potential cascading effects include the introduction of new vulnerabilities due to inconsistent or incorrect usage of constants.
• Business impact could involve increased development costs and time due to the difficulty in managing and fixing bugs or vulnerabilities.

• Prevention Guidelines:

• Specific code-level fixes include defining all symbolic constants in a centralized location such as a configuration file or constants class.
• Security best practices involve regularly reviewing and refactoring code to ensure constants are isolated and consistently used.
• Recommended tools and frameworks include static code analysis tools that can help identify instances of decentralized constant definitions.
