Description
A named-callable or method control element has a signature that
supports a variable (variadic) number of parameters or arguments.
Common consequences
• Other: Reduce Reliability — This issue can prevent the product from running reliably. If the relevant code is reachable by an attacker, then this reliability problem might introduce a vulnerability.
With variadic arguments, it can be difficult or inefficient for manual analysis to be certain of which function/method is being invoked.
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.)
