CWE-140: Improper Neutralization of Delimiters

What is Improper Neutralization of Delimiters?

• Overview: The vulnerability occurs when software incorrectly handles delimiters, which are characters used to separate different parts of data or commands. This improper handling can lead to unintended command executions or data interpretations.

• Exploitation Methods:

• Attackers can manipulate inputs to inject commands or data, taking advantage of unneutralized delimiters.
• Common attack patterns include command injection, SQL injection, and data manipulation by exploiting improperly handled delimiters.

• Security Impact:

• Direct consequences include unauthorized command execution and data leakage.
• Potential cascading effects involve further system compromise and data corruption.
• Business impact could be loss of sensitive data, damage to reputation, and regulatory penalties.

• Prevention Guidelines:

• Specific code-level fixes involve validating and sanitizing all input data to ensure delimiters are properly neutralized.
• Security best practices include using parameterized queries for database interactions and employing input validation libraries.
• Recommended tools and frameworks include static code analysis tools to detect vulnerabilities and secure coding frameworks like OWASP ESAPI.
