CVE-2022-29045 : What You Need to Know

Jenkins promoted builds Plugin versions prior to 3.10.1 are vulnerable to stored cross-site scripting (XSS) attacks due to insufficient input validation.

Understanding CVE-2022-29045

This CVE pertains to a security vulnerability in the Jenkins promoted builds Plugin that could allow attackers to execute XSS attacks.

What is CVE-2022-29045?

CVE-2022-29045 is a stored cross-site scripting (XSS) vulnerability found in Jenkins promoted builds Plugin versions earlier than 3.10.1. The issue arises from inadequate validation of user inputs, enabling malicious actors with certain permissions to execute XSS attacks.

The Impact of CVE-2022-29045

If exploited, attackers could insert malicious scripts into the name and description of Promoted Build parameters, leading to unauthorized access, data theft, and potential system compromise.

Technical Details of CVE-2022-29045

This section outlines specific technical aspects of the vulnerability.

Vulnerability Description

Jenkins promoted builds Plugin versions up to 3.10.1 fail to properly escape user-supplied data in views displaying parameters. This oversight allows attackers with specific permissions to inject and execute malicious scripts within the context of the affected application.

Affected Systems and Versions

The vulnerability affects Jenkins promoted builds Plugin versions prior to 3.10.1, with the exception of version 873.v6149db_d64130.

Exploitation Mechanism

Exploitation of CVE-2022-29045 involves an attacker with Item/Configure permission leveraging the lack of input sanitization to inject malicious scripts that execute within the application's user interface.

Mitigation and Prevention

To protect systems from CVE-2022-29045, immediate actions and long-term security practices are recommended.

Immediate Steps to Take

Users are advised to update the Jenkins promoted builds Plugin to version 3.10.1 or higher to mitigate the XSS vulnerability. Additionally, restricting access permissions can help reduce the attack surface.

Long-Term Security Practices

Implement secure coding practices, conduct regular security audits, and educate users on the importance of input validation and XSS prevention to enhance overall system security.

Patching and Updates

Regularly applying security patches and staying informed about security advisories from Jenkins project is crucial for addressing known vulnerabilities and maintaining a secure software environment.
