The code performs a comparison between two entities, but the comparison examines the wrong factors or characteristics of the entities, which can lead to incorrect results and resultant weaknesses.

CWE-1025: Comparison Using Wrong Factors

Code examples

Illustrative examples from MITRE showing how the weakness appears in code.

In the example below, two Java String objects are declared and initialized with the same string values. An if statement is used to determine if the strings are equivalent.

Vulnerable example

java

String str1 = new String("Hello");

Safe example

java

if (str1.equals(str2)) {

However, the if statement will not be executed as the strings are compared using the "==" operator. For Java objects, such as String objects, the "==" operator compares object references, not object values. While the two String objects above contain the same string values, they refer to different object references, so the System.out.println statement will not be executed. To compare object values, the previous code could be modified to use the equals method:
