CVE-2022-34192 in ontrack Plugin
Summary
by MITRE • 06/23/2022
Jenkins ontrack Jenkins Plugin 4.0.0 and earlier does not escape the name of Ontrack: Multi Parameter choice, Ontrack: Parameter choice, and Ontrack: SingleParameter 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-2022-34192 affects the Jenkins Ontrack plugin version 4.0.0 and earlier, presenting a stored cross-site scripting vulnerability that poses significant security risks to Jenkins environments. This issue specifically targets the parameter display functionality within Jenkins build views, where user-supplied parameter names are not properly sanitized or escaped before being rendered in web interfaces. The vulnerability exists in the handling of three specific parameter types: Ontrack: Multi Parameter choice, Ontrack: Parameter choice, and Ontrack: SingleParameter parameters, which are commonly used in Jenkins pipelines for configuration management and build automation processes.
The technical flaw stems from insufficient input validation and output escaping mechanisms within the plugin's rendering logic. When Jenkins displays parameter information in build views or configuration screens, the plugin fails to properly escape special characters in parameter names that could contain malicious script code. This stored XSS vulnerability allows attackers who possess the Item/Configure permission level to inject malicious JavaScript code into parameter names, which then executes whenever the affected views are accessed by other users. The vulnerability is classified under CWE-79 as a cross-site scripting flaw, specifically manifesting as a stored XSS variant where the malicious payload is permanently stored on the server and executed during subsequent page views.
The operational impact of this vulnerability extends beyond simple script execution, as it provides attackers with potential access to sensitive build information, credentials, and system configurations. An attacker with Item/Configure permissions can craft malicious parameter names containing JavaScript payloads that may steal session cookies, redirect users to malicious sites, or perform actions on behalf of authenticated users. This vulnerability is particularly concerning in enterprise environments where Jenkins serves as a central automation platform, as it could enable attackers to escalate privileges, access confidential build artifacts, or disrupt continuous integration workflows. The vulnerability aligns with ATT&CK technique T1211 for exploitation of vulnerabilities and T1078 for valid accounts usage, as it leverages legitimate user permissions to execute malicious code.
Mitigation strategies for CVE-2022-34192 should prioritize immediate plugin updates to version 4.0.1 or later, which contain the necessary patches to properly escape parameter names during display operations. Organizations should also implement additional security measures such as restricting Item/Configure permissions to only essential personnel, implementing content security policies to prevent script execution, and conducting regular security audits of Jenkins plugins and configurations. Network segmentation and monitoring of Jenkins environments can help detect suspicious parameter modifications, while regular security training for developers and administrators can reduce the risk of privilege escalation through social engineering attacks. The vulnerability demonstrates the critical importance of proper input sanitization and output escaping in web applications, particularly in automation platforms where user input directly influences system behavior and security posture.
