CVE-2026-76727

A buffer overflow vulnerability exists in the API endpoint of HPE Networking Instant On that could allow an authenticated attacker with administrative privileges to cause a denial of service. Successful exploitation could interrupt the normal operation of the affected service, which recovers without manual intervention.

An authenticated path traversal vulnerability exists in the command line interface of HPE Networking Instant On. Successful exploitation could allow an attacker with administrative access to modify a limited set of files on the underlying operating system and to interrupt the normal operation of the affected service.

A buffer overflow vulnerability exists in the underlying operating system of HPE Networking Instant On. Successful exploitation could allow a low-privilege authenticated local attacker to interrupt the normal operation of the affected service.

A sensitive information disclosure vulnerability exists in the underlying OS of HPE Networking Instant On. Successful exploitation by an authenticated local attacker with high privileges could retrieve information useful for further access to network services, but only if certain preconditions outside attacker's control are met.

A memory corruption vulnerability in the affected interface of HPE Networking Instant On could allow an unauthenticated remote attacker to conduct a denial of service attack. Successful exploitation could interrupt normal operation and access limited information within the component.

A denial-of-service vulnerability in the API endpoint of HPE Networking Instant On could allow an authenticated attacker with administrative privileges to cause a denial of service. The service resumes without manual intervention.

A local privilege-escalation vulnerability in the affected daemon of HPE Networking Instant On could allow a local attacker to achieve arbitrary code execution with root privileges if certain preconditions are met.

An authentication bypass vulnerability in the captive portal of HPE Networking Instant On could allow an unauthenticated remote attacker to circumvent existing authentication controls. Successful exploitation could allow limited data access and limited changes.

An authentication bypass vulnerability in the PAPI protocol of HPE Networking Instant On APs could allow an unauthenticated adjacent attacker to circumvent authentication controls. Successful exploitation could allow sending unauthorized network traffic to the target device.

A format string vulnerability in the API endpoint of HPE Networking Instant On APs could allow an authenticated remote attacker with high privileges to cause memory corruption with modified input. Successful exploitation could lead to DoS or remote code execution.
