Vulnerability Data

Wazuh is a free and open source platform used for threat prevention, detection, and response. fillData() implementation does not check whether value is NULL or not before calling os_strdup() on it. A compromised agent can cause a crash of analysisd…

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and code evaluation can discover instances where return values are ignored.

Requiring a documented development process and coding standards can mandate explicit checking of all function return values.

Engineering principles can mandate defensive coding such as explicit null checks before dereference.

finds

Security testing in development and acceptance can detect missing return-value checks.

prevents

Secure development life cycle mandates verification of return values to prevent undetected failures.

prevents

Application security requirements include input/output validation and error handling that covers return-value checks.

degrades

Secure system architecture and engineering principles require robust error handling and defensive coding practices.

prevents

Secure coding explicitly requires checking return values to avoid CWE-252.
