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.)
Effectiveness = High
Potential Mitigations
Phase: Requirements
The choice between a language which has named or unnamed exceptions needs to be done.
While unnamed exceptions exacerbate the chance of not properly dealing with an exception,
named exceptions suffer from the up call version of the weak base class problem.
