The product does not properly verify that the source of data or communication is valid.
| Impact | Scope | Explanation |
|---|---|---|
| Gain Privileges or Assume Identity, Varies by Context | Access Control, Other | An attacker can access any functionality that is inadvertently accessible to the source. |
| Method | Approach | Effectiveness |
|---|---|---|
| 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.) | - |
