CWE-482: Comparing instead of Assigning
The code uses an operator for comparison when the intention was to perform an assignment.
How it's found
Comparing instead of Assigning is a specific, narrowly defined instance of a broader pattern. Testers confirm it with targeted code review and a proof-of-concept input that exercises the exact code path this weakness describes.
In many languages, the compare statement is very close in appearance to the assignment statement; they are often confused.
Consequences
- Unexpected State: The assignment will not take place, which should cause obvious program execution problems.
Mitigations
- Testing: Many IDEs and static analysis products will detect this problem.
