Vulnerability reports are an opportunity to prevent a cyber security incident before it occurs. Vulnerabilities reported to CERT NZ range in severity and complexity.
64 vulnerabilities were reported to CERT NZ in 2021, with 27 being managed under our Coordinated Vulnerability Disclosure (CVD)* service.
*The CVD service is used when the person reporting the vulnerability doesn’t want, or has been unable, to contact the vendor directly. CERT NZ evaluates the scope and severity of the reported vulnerability before making the decision to apply the vulnerability disclosure coordination role.
