CVE-2022-43417: Vulnerability in Jenkins project Jenkins Katalon Plugin
Jenkins Katalon Plugin 1.0.32 and earlier does not perform permission checks in several HTTP endpoints, allowing attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.
AI Analysis
Technical Summary
CVE-2022-43417 is a medium-severity vulnerability affecting the Jenkins Katalon Plugin version 1.0.32 and earlier. The vulnerability arises because the plugin fails to enforce proper permission checks on several HTTP endpoints. Specifically, users with Overall/Read permissions—who normally have limited access—can exploit this flaw to make the Jenkins server connect to an attacker-specified URL using credentials IDs that the attacker has obtained through other means. This behavior allows an attacker to indirectly capture credentials stored within Jenkins by leveraging the plugin's functionality to perform unauthorized network requests with those credentials. The vulnerability is classified under CWE-862, which relates to improper authorization. The CVSS 3.1 base score is 4.3, reflecting a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), limited confidentiality impact (C:L), and no impact on integrity or availability (I:N/A:N). No known exploits are reported in the wild, and no patches are linked in the provided data, suggesting that remediation may require updating the plugin to a fixed version once available or applying configuration workarounds. The vulnerability's exploitation requires that the attacker has at least Overall/Read permissions on the Jenkins instance, which is a relatively low privilege level in many Jenkins setups, increasing the risk if such permissions are widely granted. The attack does not require user interaction and can be performed remotely over the network, making it a viable vector for internal or external attackers with some access to the Jenkins environment.
Potential Impact
For European organizations, this vulnerability poses a risk primarily to the confidentiality of sensitive credentials stored within Jenkins environments. Jenkins is widely used in continuous integration and continuous deployment (CI/CD) pipelines, which often contain credentials for accessing critical infrastructure, cloud services, and production environments. Unauthorized access to these credentials could lead to further compromise of internal systems, data exfiltration, or disruption of development and deployment processes. Since the vulnerability requires only Overall/Read permissions, which may be granted to a broad set of users or service accounts, the attack surface is significant. Organizations with large development teams or third-party integrations might inadvertently expose themselves. The lack of impact on integrity and availability reduces the risk of direct service disruption, but the confidentiality breach can have cascading effects, including unauthorized access to other systems and potential compliance violations under regulations such as GDPR if personal data is involved. The absence of known exploits in the wild suggests limited active exploitation currently, but the vulnerability remains a concern for organizations relying on Jenkins Katalon Plugin in their CI/CD workflows.
Mitigation Recommendations
European organizations should take immediate steps to mitigate this vulnerability. First, they should verify the version of the Jenkins Katalon Plugin in use and upgrade to a version where this vulnerability is fixed once available. If no fixed version exists yet, organizations should restrict Overall/Read permissions to only trusted users and service accounts, minimizing the number of principals who can exploit this flaw. Implementing strict access control policies and auditing permission assignments in Jenkins is critical. Additionally, organizations should monitor Jenkins logs for unusual HTTP requests or connections to unexpected URLs that could indicate exploitation attempts. Network segmentation and firewall rules can be employed to restrict Jenkins servers from making outbound connections to untrusted external addresses, limiting the attacker's ability to leverage the vulnerability. Credential rotation policies should be enforced to reduce the impact of any potential credential exposure. Finally, organizations should consider implementing additional security controls such as credential vaulting solutions that integrate with Jenkins to reduce reliance on stored credentials within the plugin.
