CWE-913: Improper Control of Dynamically-Managed Code Resources
Learn about CWE-913 (Improper Control of Dynamically-Managed Code Resources), its security impact, exploitation methods, and prevention guidelines.
What is Improper Control of Dynamically-Managed Code Resources?
• Overview: Improper Control of Dynamically-Managed Code Resources (CWE-913) occurs when a software application does not adequately control or restrict access to code resources that can be managed or altered dynamically, such as variables, objects, and executable code, allowing unintended access or modifications.
• Exploitation Methods:
- Attackers can exploit this vulnerability by injecting malicious code or altering existing code resources to perform unauthorized actions.
- Common attack patterns include code injection, code tampering, and manipulation of dynamically-managed variables or objects.
• Security Impact:
- Direct consequences of successful exploitation include unauthorized code execution, data corruption, and loss of integrity.
- Potential cascading effects include privilege escalation, system crashes, and unauthorized access to sensitive information.
- Business impact may involve financial losses, reputational damage, and legal liabilities due to data breaches or system downtime.
• Prevention Guidelines:
- Specific code-level fixes include validating and sanitizing all inputs that interact with dynamically-managed code resources.
- Security best practices involve implementing strict access controls, employing least privilege principles, and conducting regular code reviews.
- Recommended tools and frameworks include static and dynamic analysis tools to identify and mitigate vulnerabilities, and secure coding libraries that enforce access restrictions.
