CVE-2023-20097 : Vulnerability Insights and Analysis

This CVE, titled "Cisco Access Point Software Command Injection Vulnerability," was published on March 23, 2023, by Cisco. It presents a security issue in Cisco access points (AP) software that could potentially allow an authenticated, local attacker to inject and execute arbitrary commands with root privileges.

Understanding CVE-2023-20097

This section will delve into the details of CVE-2023-20097, explaining what this vulnerability is, its impact, technical aspects, and how to mitigate and prevent exploitation.

What is CVE-2023-20097?

The vulnerability in Cisco access points (AP) software stems from improper input validation of commands sent from a wireless controller to the AP. An attacker with Administrator access to the controller's CLI could exploit this flaw by issuing a command with specially crafted arguments. Successful exploitation could grant the attacker full root access on the AP.

The Impact of CVE-2023-20097

Given the ability to execute arbitrary commands with root privileges, a malicious actor exploiting this vulnerability could potentially gain complete control over the affected Cisco Aironet Access Point Software. This could result in the compromise of sensitive information, unauthorized access, and disruption of services.

Technical Details of CVE-2023-20097

This section will outline the technical aspects of CVE-2023-20097, including the vulnerability description, affected systems and versions, as well as the exploitation mechanism.

Vulnerability Description

The vulnerability allows an authenticated, local attacker to inject arbitrary commands with root privileges due to improper input validation in the Cisco access points (AP) software.

Affected Systems and Versions

The vulnerability affects the Cisco Aironet Access Point Software, with the specific version being reported as 'n/a.'

Exploitation Mechanism

An attacker needs Administrator access to the wireless controller's CLI to exploit the vulnerability by issuing a command with crafted arguments. This would potentially grant the attacker full root access on the AP.

Mitigation and Prevention

To address CVE-2023-20097, it is crucial to take immediate steps, adopt long-term security practices, and ensure systems are up to date with necessary patches and updates.

Immediate Steps to Take

Organizations should restrict access to the CLI of the controller, monitor for any suspicious activities, and apply security best practices to prevent unauthorized command injections.

Long-Term Security Practices

Implementing the principle of least privilege, conducting regular security assessments, and providing security awareness training to personnel can help bolster the overall security posture against such vulnerabilities.

Patching and Updates

Cisco may release patches or updates to address CVE-2023-20097. Organizations are advised to regularly check for and apply these patches to mitigate the risk of exploitation and enhance the security of their systems.
