CWE-290: Authentication Bypass by Spoofing

 
Authentication Bypass by Spoofing
Weakness ID: 290 (Weakness Base)Status: Incomplete
+ Description

Description Summary

This attack-focused weakness is caused by improperly implemented authentication schemes that are subject to spoofing attacks.
+ Time of Introduction
  • Architecture and Design
  • Implementation
+ Demonstrative Examples

Example 1

Here, an authentication mechanism implemented in Java relies on an IP address for source validation. If an attacker is able to spoof the IP, however, he may be able to bypass such an authentication mechanism.

(Bad Code)
Java
String sourceIP = request.getRemoteAddr();
if (sourceIP != null && sourceIP.equals(APPROVED_IP)) {
authenticated = true;
}
