CVE-2023-22785 : What You Need to Know

This CVE-2023-22785 pertains to unauthenticated buffer overflow vulnerabilities in services accessed by the PAPI protocol in Aruba Access Points running InstantOS and ArubaOS 10, manufactured by Hewlett Packard Enterprise (HPE).

Understanding CVE-2023-22785

This vulnerability allows for unauthenticated remote code execution on the underlying operating system of affected devices by exploiting buffer overflow weaknesses in multiple services accessible through the PAPI (Aruba's access point management protocol) UDP port (8211).

What is CVE-2023-22785?

The vulnerability in CVE-2023-22785 arises from buffer overflow issues in various services, enabling threat actors to execute arbitrary code on impacted systems without the need for authentication. By sending specially crafted packets to the PAPI UDP port, attackers can exploit these vulnerabilities to achieve privileged access and execute malicious code.

The Impact of CVE-2023-22785

With a base score of 9.8 (CVSS:3.1) and classified as critical, this vulnerability poses a severe risk to affected systems. The attack vector is through the network, with high impacts on availability, confidentiality, and integrity. No user interaction or privileges are required for exploitation, maintaining an unchanged scope, and demanding immediate attention to prevent potential system compromise.

Technical Details of CVE-2023-22785

This section outlines specific technical aspects of the CVE-2023-22785 vulnerability.

Vulnerability Description

The vulnerability stems from buffer overflow weaknesses in underlying services accessible via the PAPI (Aruba's access point management protocol) UDP port (8211), enabling unauthenticated remote code execution on affected systems.

Affected Systems and Versions

The vulnerability impacts Aruba Access Points running InstantOS 8.10.x.x (8.10.0.2 and below) and ArubaOS 10.3.x.x (10.3.1.4 and below). It is crucial to review the reference document for additional affected versions and details.

Exploitation Mechanism

Threat actors can exploit these vulnerabilities by sending specially crafted packets to the targeted PAPI UDP port, triggering buffer overflow scenarios that allow for the execution of arbitrary code on the underlying operating system.
