Description
The product contains an expression that will always evaluate to true.
Common consequences
• Other: Quality Degradation, Varies by Context
Potential mitigations
• [Implementation] Consider refactoring the code, or determine if the code is not including a condition that could cause the expression to become false.
Detection methods
• Automated Static Analysis: Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
