No vulnerability data in CISA KEV for CWE-248
An exception is thrown from a function, but it is not caught.
When an exception is not caught, it may cause the program to crash or expose sensitive information.
| Impact | Scope | Explanation |
|---|---|---|
| DoS: Crash, Exit, or Restart, Read Application Data | Availability, Confidentiality | An uncaught exception could cause the system to be placed in a state that could lead to a crash, exposure of sensitive information or other unintended behaviors. |
| 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.) | High |
