Learn about CVE-2023-22780 involving unauthenticated buffer overflow vulnerabilities in Aruba Access Points by Hewlett Packard Enterprise (HPE). Take immediate steps to prevent exploitation.

This CVE involves unauthenticated buffer overflow vulnerabilities in services accessed by the PAPI Protocol, affecting Aruba Access Points running InstantOS and ArubaOS 10, provided by Hewlett Packard Enterprise (HPE). These vulnerabilities could allow remote attackers to execute arbitrary code as a privileged user on the underlying operating system.

Understanding CVE-2023-22780

This section will delve into what CVE-2023-22780 entails, its impact, technical details, and mitigation strategies.

What is CVE-2023-22780?

CVE-2023-22780 comprises buffer overflow vulnerabilities in multiple services accessed by the PAPI protocol, specifically on UDP port 8211. Attackers could exploit this vulnerability by sending specially crafted packets, enabling them to execute arbitrary code without requiring authentication.

The Impact of CVE-2023-22780

The impact of these vulnerabilities is critical, with a CVSS base score of 9.8 out of 10. Successful exploitation could lead to unauthenticated remote code execution with high availability, confidentiality, and integrity impacts, allowing attackers to gain privileged access to the system.

Technical Details of CVE-2023-22780

This section will provide a deeper dive into the technical aspects of CVE-2023-22780, including vulnerability description, affected systems, versions, and exploitation mechanisms.

Vulnerability Description

The vulnerability involves buffer overflow issues in various underlying services, facilitating unauthenticated remote code execution when malicious packets are sent to the PAPI UDP port (8211). This could result in executing arbitrary code as a privileged user on the system.

Affected Systems and Versions

Aruba Access Points running InstantOS and ArubaOS 10 are impacted. Specifically, InstantOS 8.10.x.x version 8.10.0.2 and below, ArubaOS 10.3.x.x version 10.3.1.4 and below, and further details can be found in the reference document.

Exploitation Mechanism

The exploitation of these vulnerabilities involves crafting packets to exploit buffer overflow in the PAPI protocol on the designated UDP port (8211), enabling attackers to execute unauthorized code on the system.

Mitigation and Prevention

In response to CVE-2023-22780, it is crucial for affected organizations to take immediate action and implement long-term security practices to prevent exploitation and mitigate risks effectively.
