CVE-2023-45614 : Exploit Details and Defense Strategies

A buffer overflow vulnerability has been identified in the CLI service of Aruba's Access Points, potentially allowing unauthenticated remote code execution. This CVE poses a significant risk as successful exploitation could lead to arbitrary code execution as a privileged user on the underlying operating system.

Understanding CVE-2023-45614

This section will delve into the specifics of the CVE-2023-45614, outlining its impact, technical details, and mitigation strategies.

What is CVE-2023-45614?

The CVE-2023-45614 involves buffer overflow vulnerabilities in the CLI service of Aruba's Access Points, enabling attackers to execute arbitrary code remotely without authentication. This exploit targets the PAPI (Aruba's access point management protocol) UDP port, posing severe risks to the affected systems.

The Impact of CVE-2023-45614

The impact of CVE-2023-45614 is rated as critical with a CVSS base score of 9.8, signifying a high severity level. The vulnerability's exploitation could result in unauthorized remote code execution with elevated privileges, posing a significant threat to the security and integrity of the underlying operating system.

Technical Details of CVE-2023-45614

Let's explore the technical aspects of CVE-2023-45614, including the vulnerability description, affected systems, and exploitation mechanism.

Vulnerability Description

The vulnerability stems from buffer overflow issues in the CLI service, triggered by specially crafted packets sent to the PAPI UDP port. This flaw allows attackers to execute arbitrary code as privileged users on the target system.

Affected Systems and Versions

The vulnerable systems include various Aruba Access Points running specific versions of ArubaOS and InstantOS, such as ArubaOS 10.5.x.x, 10.4.x.x, InstantOS 8.11.x.x, InstantOS 8.10.x.x, and InstantOS 8.6.x.x. Users of these systems are at risk of remote code execution.

Exploitation Mechanism

Attackers can exploit this vulnerability by sending specially crafted packets to the PAPI UDP port (8211), triggering buffer overflow conditions. This allows them to execute malicious code remotely, potentially compromising the entire system.

Mitigation and Prevention

To secure systems against CVE-2023-45614, immediate actions and long-term security practices are essential to mitigate the risks effectively.

Immediate Steps to Take

Apply patches and updates provided by Hewlett Packard Enterprise (HPE) for Aruba Access Points to address the buffer overflow vulnerabilities.
Implement network segmentation and access controls to restrict unauthorized access to the affected systems.

Long-Term Security Practices

Regularly monitor and audit network traffic for any suspicious activities or unauthorized access attempts.
Conduct security assessments and penetration testing to identify and remediate potential vulnerabilities across the network infrastructure.

Patching and Updates

Stay informed about security advisories and updates released by HPE for Aruba Access Points. Timely patch management is crucial to ensure the continued protection of your systems.
