14 vulnerabilities classified as CWE-390 (未有动作错误条件的检测). AI Chinese analysis included.
CWE-390 represents a critical logic flaw where software identifies an error condition but fails to execute any remedial action. This weakness typically arises when developers detect exceptions or invalid states but ignore them, allowing the program to continue execution with corrupted data or undefined behavior. Attackers exploit this by triggering the specific error condition, causing the application to proceed in an unstable state that may lead to data corruption, denial of service, or further vulnerabilities like buffer overflows. To prevent this, developers must implement robust error handling strategies that include logging the incident, notifying administrators, and safely terminating or resetting the process. Ensuring that every detected error triggers a defined response mechanism is essential for maintaining system integrity and preventing silent failures that compromise security and reliability.
