Vulnerability from nvd – Published: 2026-09-29 19:28 – Updated: 2026-09-30 12:34

Title

Authenticated Buffer Overflow Vulnerability in the API Endpoint of HPE Networking Instant On Causes Denial-of-Service

Summary

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 allow an attacker to interrupt the normal operation of the affected service, which recovers without manual intervention.

Severity

2.7 (Low)

CVE-2026-76735 (GCVE-0-2026-76735)

Vulnerability from nvd – Published: 2026-09-29 19:28 – Updated: 2026-09-30 20:01

Title

Authenticated Local Sensitive Information Disclosure in HPE Networking Instant On

Summary

A sensitive information disclosure vulnerability exists in the underlying operating system of HPE Networking Instant On. Successful exploitation could allow an authenticated local attacker with high privileges to retrieve information which could be used to potentially gain further access to network services supported by HPE Networking Instant On, only if certain preconditions outside of the attacker's control are met.

Severity

4.1 (Medium)

CVE-2026-76726 (GCVE-0-2026-76726)

Vulnerability from nvd – Published: 2026-09-29 19:28 – Updated: 2026-10-01 03:55

Title

Authentication Bypass Leading to Unauthorized Network Access in HPE Networking Instant ON API Endpoint

Summary

An authentication bypass vulnerability in the API endpoint of HPE Networking Instant ON could allow an unauthenticated remote attacker to bypass network access controls if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to obtain unauthorized access to restricted networks.

Severity

8.1 (High)

CVE-2026-76724 (GCVE-0-2026-76724)

Vulnerability from nvd – Published: 2026-09-29 19:28 – Updated: 2026-10-01 03:55

Title

Unauthenticated Adjacent Command Injection Vulnerability in HPE Networking Instant ON APs Command Line Interface (CLI) Accessed by the PAPI Protocol

Summary

A command injection vulnerability exists in CLI of the affected HPE Networking Instant ON APs that could allow an unauthenticated adjacent attacker to perform command injection by sending specially crafted packets. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system.

Severity

9.6 (Critical)

Title

Authenticated Local Sensitive Information Disclosure in HPE Networking Instant On

Summary

A sensitive information disclosure vulnerability exists in the underlying operating system of HPE Networking Instant On. Successful exploitation could allow an authenticated local attacker with high privileges to retrieve information which could be used to potentially gain further access to network services supported by HPE Networking Instant On, only if certain preconditions outside of the attacker's control are met.

CVE-2026-76728 (GCVE-0-2026-76728)

Vulnerability from cvelistv5 – Published: 2026-09-29 19:28 – Updated: 2026-10-01 03:55

Title

Authenticated Server-Side Request Forgery Leading to Remote Code Execution in HPE Networking Instant ON APs

Summary

A vulnerability in the API endpoint of HPE Networking Instant ON APs could allow an authenticated remote attacker with high privileges to conduct a server-side request forgery (SSRF) attack. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system.

Severity

7.2 (High)
