CVE-2022-34191 in NS-ND Integration Performance Publisher Plugin
Summary
by MITRE • 06/23/2022
Jenkins NS-ND Integration Performance Publisher Plugin 4.8.0.77 and earlier does not escape the name of NetStorm Test parameters on views displaying parameters, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.

The vulnerability identified as CVE-2022-34191 affects the Jenkins NS-ND Integration Performance Publisher Plugin version 4.8.0.77 and earlier, presenting a critical stored cross-site scripting flaw that undermines the security posture of Jenkins environments. This vulnerability specifically manifests when NetStorm Test parameters are displayed within Jenkins views, creating an avenue for malicious actors to inject persistent JavaScript payloads that execute in the context of other users' browsers. The flaw stems from insufficient input sanitization and output escaping mechanisms within the plugin's parameter display functionality, where parameter names containing malicious script code are not properly escaped before being rendered in web interfaces.
The technical exploitation of this vulnerability requires an attacker to possess the Item/Configure permission within Jenkins, which is typically granted to users who can modify job configurations and manage pipeline parameters. This permission level is commonly available to developers, build managers, and other team members who require administrative capabilities for their workflow automation tasks. Once an attacker gains this level of access, they can craft malicious parameter names containing XSS payloads that persist within the Jenkins interface, making the vulnerability particularly dangerous as it can affect any user who views the affected parameter displays. The stored nature of this XSS vulnerability means that the malicious code remains embedded in the system and executes every time the affected view is accessed, regardless of the user's authentication status or privileges.
The operational impact of CVE-2022-34191 extends beyond simple script execution, as it can enable attackers to perform a wide range of malicious activities including credential theft, session hijacking, and privilege escalation within the Jenkins environment. Attackers can leverage this vulnerability to steal Jenkins session cookies, potentially gaining unauthorized access to the Jenkins server as authenticated users with elevated privileges. The vulnerability also allows for more sophisticated attacks such as redirecting users to malicious websites, defacing Jenkins interfaces, or even establishing persistent backdoors through the execution of malicious JavaScript code in the victim's browser context. This makes the vulnerability particularly concerning for organizations that rely heavily on Jenkins for continuous integration and deployment pipelines, where the compromise of a single parameter could lead to broader system infiltration.
Organizations should immediately update their Jenkins NS-ND Integration Performance Publisher Plugin to version 4.8.0.78 or later to remediate this vulnerability, as the fix includes proper output escaping mechanisms that prevent malicious parameter names from being rendered as executable JavaScript. Security teams should also implement additional monitoring for unusual parameter naming conventions within Jenkins jobs, particularly those involving automation and performance testing workflows. The vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications, and can be categorized under ATT&CK technique T1566.001 for initial access through spearphishing attachments and T1078.004 for valid accounts usage. Organizations should consider implementing web application firewalls and content security policies to add additional layers of protection against similar vulnerabilities, while also conducting regular security audits of their Jenkins plugin ecosystem to identify and remediate other potential security weaknesses in their CI/CD infrastructure.
