CVE-2023-24455 : What You Need to Know

This is a detailed overview of CVE-2023-24455, providing essential information on the vulnerability, its impact, technical details, and mitigation steps.

Understanding CVE-2023-24455

CVE-2023-24455 is a security vulnerability found in the Jenkins visualexpert Plugin, specifically affecting versions 1.3 and earlier. The vulnerability allows attackers with specific permissions to check for the existence of a file path on the Jenkins controller file system.

What is CVE-2023-24455?

The CVE-2023-24455 vulnerability arises from a lack of restrictions on file names in methods implementing form validation in the Jenkins visualexpert Plugin. This flaw can be exploited by attackers with Item/Configure permission, granting them the ability to manipulate file paths on the Jenkins controller file system.

The Impact of CVE-2023-24455

The impact of this vulnerability is significant as it can lead to unauthorized access, data manipulation, and potentially system compromise. Attackers exploiting CVE-2023-24455 can gather sensitive information and disrupt the integrity of the Jenkins environment.

Technical Details of CVE-2023-24455

Understanding the technical aspects of CVE-2023-24455 is crucial for effectively addressing and mitigating the security risk associated with this vulnerability.

Vulnerability Description

The Jenkins visualexpert Plugin version 1.3 and earlier fail to enforce proper file name restrictions in form validation methods. This lapse allows attackers with specific permissions to exploit the system by checking for the presence of a file path of their choosing on the Jenkins controller file system.

Affected Systems and Versions

The vulnerability impacts Jenkins visualexpert Plugin versions 1.3 and earlier. Users with these versions installed are at risk of exploitation by malicious actors seeking to probe file paths on the Jenkins controller.

Exploitation Mechanism

By leveraging the lack of file name restrictions in form validation methods, attackers with Item/Configure permission can manipulate file paths to their advantage. This exploitation mechanism enables them to search for and potentially access unauthorized file paths on the Jenkins controller file system.

Mitigation and Prevention

To safeguard systems against CVE-2023-24455 and similar vulnerabilities, prompt mitigation and prevention measures are necessary.

Immediate Steps to Take

Administrators should update the Jenkins visualexpert Plugin to a secure version that includes a patch for CVE-2023-24455. Additionally, monitoring user permissions and access controls can help mitigate the risk of unauthorized file path manipulation.

Long-Term Security Practices

Implementing robust security protocols, conducting regular security audits, and providing comprehensive security training to personnel can enhance the overall resilience of the Jenkins environment against potential threats.

Patching and Updates

Regularly applying software patches and updates, particularly those addressing known vulnerabilities like CVE-2023-24455, is crucial for maintaining the security and integrity of the Jenkins platform. Stay informed about security advisories and promptly implement recommended patches to bolster system defenses.
