CWE-210 (通过自主产生的错误消息导致的信息暴露) — Vulnerability Class 2

CWE-210 represents an information disclosure weakness where software generates internal error messages that inadvertently expose sensitive data, such as database schemas, file paths, or stack traces. Attackers typically exploit this vulnerability by triggering specific error conditions, such as invalid inputs or failed authentication attempts, to observe the detailed diagnostic output. This information aids in reconnaissance, allowing adversaries to map the application’s architecture, identify vulnerable endpoints, or craft more precise exploits against underlying systems. To prevent this, developers must implement robust error handling mechanisms that decouple internal logic from user-facing feedback. This involves sanitizing error outputs, logging detailed diagnostics securely for administrative review only, and presenting generic, non-descriptive error messages to end-users. By ensuring that internal state remains hidden during failure scenarios, organizations significantly reduce the attack surface and protect critical system intelligence from malicious actors.
