CVE-2026-76730: Vulnerability in Hewlett Packard Enterprise (HPE) Instant ON
An authentication bypass vulnerability exists in the PAPI protocol of HPE Networking Instant ON APs that could allow an unauthenticated adjacent attacker to circumvent existing authentication controls. Successful exploitation could allow an attacker to circumvent certain existing authentication mechanisms and send unauthorized network traffic to the target device.
AI Analysis
Technical Summary
This vulnerability exists in the PAPI protocol implementation of HPE Instant ON access points. An unauthenticated attacker within adjacent network range can exploit this flaw to circumvent authentication mechanisms, enabling them to send unauthorized network traffic to the affected device. The issue impacts versions from 0.0.0.0 up to and including 3.4.1.0. There is no indication of active exploitation in the wild or available patches in the provided data.
Potential Impact
Successful exploitation allows an attacker to bypass authentication controls and send unauthorized network traffic to the target HPE Instant ON device. This could lead to unauthorized network activity and potential disruption or misuse of network resources. Confidentiality is not impacted, but integrity of network traffic is compromised. Availability is not affected.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor HPE advisories for updates. Until a fix is available, restricting physical or wireless adjacency to trusted users may reduce risk.
