CWE-703 (对异常条件检查或处理不恰当) — Vulnerability Class 94

94 vulnerabilities classified as CWE-703 (对异常条件检查或处理不恰当). AI Chinese analysis included.

CWE-703 represents a critical design flaw where software fails to adequately anticipate or manage rare, exceptional conditions that may arise during normal operation. This weakness typically manifests when developers assume ideal execution paths, neglecting to implement robust error handling for unexpected inputs, resource exhaustion, or environmental anomalies. Attackers exploit these gaps by triggering edge cases that bypass standard validation, potentially causing denial of service, data corruption, or unauthorized access through unhandled exceptions. To mitigate this risk, developers must adopt a defensive programming mindset, rigorously testing for boundary conditions and implementing comprehensive exception handling mechanisms. By validating all inputs and ensuring graceful degradation under stress, engineers can prevent these overlooked scenarios from becoming exploitable vulnerabilities, thereby enhancing overall system resilience and security posture against sophisticated adversarial techniques.

MITRE CWE Description
The product does not properly anticipate or handle exceptional conditions that rarely occur during normal operation of the product.
Common Consequences (1)
Confidentiality, Availability, IntegrityRead Application Data, DoS: Crash, Exit, or Restart, Unexpected State
Examples (2)
Consider the following code segment:
char buf[10], cp_buf[10]; fgets(buf, 10, stdin); strcpy(cp_buf, buf);
Bad · C
The following method throws three types of exceptions.
public void doExchange() throws IOException, InvocationTargetException, SQLException { ... }
Good · Java
public void doExchange() throws Exception { ... }
Bad · Java
