What are security concerns around error handling?

Error handling presents significant security concerns, primarily revolving around the risk of information leakage. Detailed error messages, such as stack traces, database errors, or internal system paths, can inadvertently expose sensitive system architecture, technologies used, and potential vulnerabilities to attackers. Furthermore, improper error management can lead to denial-of-service (DoS) attacks, where unhandled exceptions or resource exhaustion due to errors can render a service unavailable. Another critical risk involves the potential for bypassing security controls; unexpected error conditions might divert program execution paths, allowing attackers to circumvent authentication, authorization, or other protective measures. If error messages are generated using unsanitized user input, they could also introduce injection vulnerabilities like Cross-Site Scripting (XSS) or SQL injection. Lastly, insufficient or insecure error logging and monitoring practices hinder incident response, making it difficult to detect, investigate, and mitigate security breaches effectively.
