Glexia's Take · Automated analysis
CWE-430: Deployment of Wrong Handler
Deployment of Wrong Handler represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Integrity Other: Varies by Context Unexpected State
Developer Pattern
CWE-430 is the kind of defect developers can usually prevent with explicit validation, safer framework defaults, and tests that exercise hostile input or unsafe state transitions.
Automation confidence

Official CWE Definition
CWE-430: Deployment of Wrong Handler
The wrong "handler" is assigned to process an object.
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.
Developer And Remediation Guidance
How teams prevent and detect this weakness
Causes
- Missing validation
- Unsafe defaults
- Insufficient authorization or memory-safety invariant
Remediation
- 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.
Detection
- Code review
- SAST
- DAST
- Focused regression tests
