Insufficient Comparison
Weakness ID: 697 (Weakness Class)Status: Incomplete
+ Description

Description Summary

The software compares two entities in a security-relevant context, but the comparison is insufficient, which may lead to resultant weaknesses.

Extended Description

This weakness class covers several possibilities: (1) the comparison checks one factor incorrectly; (2) the comparison should consider multiple factors, but it does not check some of those factors at all.
