Glexia's Take · Automated analysis
CWE-622: Improper Validation of Function Hook Arguments
Improper Validation of Function Hook Arguments represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Integrity: Unexpected State
Developer Pattern
CWE-622 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
high confidence from CWE-622, 4.20.

Official CWE Definition
CWE-622: Improper Validation of Function Hook Arguments
The product adds hooks to user-accessible API functions, but it does not properly validate the arguments. This could lead to resultant vulnerabilities.
Such hooks can be used in defensive software that runs with privileges, such as anti-virus or firewall, which hooks kernel calls. When the arguments are not validated, they could be used to bypass the protection scheme or attack the product itself.
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: Ensure that all arguments are verified, as defined by the API you are protecting.
- Architecture and Design: Drop privileges before invoking such functions, if possible.
Detection
- Code review
- SAST
- DAST
- Focused regression tests
