CVE-2026-79883
HighCVSS 8.3Exploitation Probability (EPSS)
Low risk7th percentile - higher than 7% of all known CVEs
Summary
A buffer overflow vulnerability in the PAPI protocol of HPE Networking AOS-10 could allow an unauthenticated adjacent attacker to access sensitive information. Successful exploitation could allow an attacker to retrieve information which could be used to potentially gain further access to network services supported by AOS-10, and to interrupt the normal operation of the affected service.
Risk Assessment
Information leakage may help an attacker gain further access to network services. At the same time, disruption of the affected service may occur.
Recommendation
Apply the AOS-10 fix and restrict access to the PAPI protocol from adjacent networks while monitoring for unusual traffic on service ports.
Other vulnerabilities in AOS-10
See all- CVE-2026-79876Critical
A sensitive information disclosure vulnerability in the Wi-Fi frame processing of AOS-10 could allow an unauthenticated adjacent attacker to access sensitive information. Successful exploitation could allow an attacker to retrieve information which could be used to potentially gain further access to network services supported by AOS-10, or to interrupt the normal operation of the affected service.
- CVE-2026-79874Critical
An authentication bypass in the API of AOS-10 allows an unauthenticated adjacent attacker to circumvent existing authentication controls. Successful exploitation could allow an attacker to gain administrative access, modify system configurations, and access or manipulate sensitive data.
- CVE-2026-79873Critical
Authentication bypass vulnerabilities in the PAPI protocol of AOS-10 could allow an unauthenticated adjacent attacker to circumvent existing authentication controls. Successful exploitation could allow an attacker to gain administrative access, modify system configurations, and access or manipulate sensitive data on affected devices.
- CVE-2026-79871Critical
A sensitive information disclosure vulnerability in the command line interface of AOS-10 could allow an unauthenticated remote attacker to access sensitive information. Successful exploitation could allow an attacker to retrieve information which could be used to potentially gain further access to network services supported by AOS-10.
- CVE-2026-79869Critical
Authentication bypass vulnerabilities in the affected interface of AOS-10 could allow an unauthenticated adjacent attacker to circumvent existing authentication controls. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system.
- CVE-2026-79865Critical
A memory corruption vulnerability in the affected interface of AOS-10 could allow an unauthenticated adjacent attacker to achieve remote code execution. Successful exploitation could allow an attacker to execute arbitrary code as a privileged user on the underlying operating system.
- CVE-2026-79864Critical
Command injection vulnerabilities exist in the affected interface of AOS-10 that could allow an unauthenticated adjacent attacker to perform command injection. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system.
- CVE-2026-79861Critical
There is a command injection vulnerability in AOS-10 that could lead to unauthenticated remote code execution by sending specially crafted PAPI packets. Successful exploitation results in the ability to execute arbitrary code as a privileged user on the underlying operating system.
- CVE-2026-79854Critical
A vulnerability in the affected interface of AOS-10 could allow an unauthenticated remote attacker to conduct SQL injection attacks against the AOS-10 instance. Successful exploitation could allow an attacker to execute arbitrary commands on the underlying operating system.
- CVE-2026-79853Critical
Sensitive information disclosure vulnerabilities in the affected interface of AOS-10 could allow an unauthenticated remote attacker to obtain sensitive information from the affected system. Successful exploitation could allow an attacker to execute arbitrary commands on the underlying operating system.
