Technical Details of CVE-2023-28678

This section delves into the technical aspects of CVE-2023-28678, providing a deeper understanding of the vulnerability.

Vulnerability Description

The vulnerability stems from the lack of proper file name escaping in Jenkins Cppcheck Plugin versions 1.26 and below. This oversight allows malicious content within report files to execute arbitrary scripts in the context of the Jenkins UI, opening the door to XSS attacks.

Affected Systems and Versions

The issue impacts systems running Jenkins Cppcheck Plugin version 1.26 and earlier. Users of these versions are susceptible to the stored XSS vulnerability if unaddressed.

Exploitation Mechanism

Attackers who can manipulate the contents of Cppcheck report files can insert malicious scripts or payloads that, when rendered on the Jenkins UI, execute in the context of the user's session, potentially leading to unauthorized actions or data theft.

Mitigation and Prevention

In this section, we explore strategies to mitigate the risks associated with CVE-2023-28678 and prevent exploitation of the vulnerability.

Immediate Steps to Take

Users should update Jenkins Cppcheck Plugin to a non-vulnerable version (post 1.26) to safeguard their systems against the XSS vulnerability. Additionally, employing content security policies and input validation measures can help mitigate the risk of XSS attacks.

Long-Term Security Practices

Implementing secure coding practices, conducting regular security assessments, and staying informed about plugin vulnerabilities through vendor advisories are essential long-term security practices to protect against similar vulnerabilities.

Patching and Updates

Users are advised to stay updated on security advisories from Jenkins Project and promptly apply patches and updates released to address CVE-2023-28678. Regularly updating Jenkins plugins and monitoring security bulletins can help maintain a secure environment.
