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.)

Potential Mitigations
Phase: Implementation
Within Java, use .equals() to compare string values. Within JavaScript, use == to compare string
values. Within PHP, use == to compare a numeric value to a string value. (PHP converts the
string to a number.)
