CVE-2026-76752
CriticalCVSS 9.8Summary
Authentication bypass vulnerabilities exist in the web-based management and API interfaces of HPE Networking ClearPass Policy Manager. Successful exploitation could allow an unauthenticated remote attacker to circumvent existing authentication controls and gain administrative access to the affected system.
Risk Assessment
An unauthenticated attacker could gain full administrative access, potentially leading to complete system compromise, data breach, and service disruption.
Recommendation
Urgently apply vendor patches and strengthen authentication mechanisms, e.g., by implementing MFA and restricting access to management interfaces.
