The product adds hooks to user-accessible API functions, but it does not properly validate the arguments. This could lead to resultant vulnerabilities.
Extended description
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.
Best practices to prevent this CWE
Phase: Architecture and Design
Ensure that all arguments are verified, as defined by the API you are protecting.
Phase: Architecture and Design
