CWE-430: Deployment of Wrong Handler
The wrong "handler" is assigned to process an object.
How it's found
Deployment of Wrong Handler is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
An example of deploying the wrong handler would be calling a servlet to reveal source code of a .JSP file, or automatically "determining" type of the object even if it is contradictory to an explicitly specified type.
Consequences
- Varies by Context, Unexpected State
Mitigations
- Architecture and Design: Perform a type check before interpreting an object.
- Architecture and Design: Reject any inconsistent types, such as a file with a .GIF extension that appears to consist of PHP code.
