CWE-779 (日志记录过多数据) — Vulnerability Class 12

CWE-779 represents a logging weakness where applications record excessive or unnecessary data, creating voluminous log files that obscure critical security events. This flaw is typically exploited by attackers who intentionally trigger high-volume logging to cause denial-of-service conditions through disk space exhaustion or to mask malicious activities within the noise of redundant entries. Consequently, system administrators struggle to detect anomalies, hindering forensic analysis and incident response efforts during an active breach. To avoid this vulnerability, developers must implement strict logging policies that prioritize essential security and operational data while suppressing verbose debug information in production environments. By configuring log levels appropriately and filtering sensitive or redundant data, organizations ensure that logs remain manageable, searchable, and effective for monitoring system health and identifying genuine threats without overwhelming infrastructure resources.
