CVE-2022-41228 is a high-severity vulnerability affecting the Jenkins NS-ND Integration Performance Publisher Plugin, versions 4.8.0.129 and earlier. The core issue is a missing permission check that allows users with Overall/Read permissions—typically low-privileged users—to exploit the plugin to connect to an attacker-controlled webserver using attacker-supplied credentials. This vulnerability stems from CWE-862 (Missing Authorization), indicating that the plugin fails to properly verify whether the user is authorized to perform certain actions. Because Jenkins is widely used for continuous integration and continuous delivery (CI/CD) pipelines, this flaw can be leveraged by attackers to perform unauthorized network connections, potentially leading to information disclosure, integrity violations, or availability impacts. The CVSS v3.1 score of 8.8 (high) reflects the vulnerability's network attack vector, low attack complexity, requirement for low privileges (Overall/Read), no user interaction, and high impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the vulnerability's characteristics make it a significant risk if left unpatched. The lack of a patch link in the provided data suggests that users should verify the availability of updates from the Jenkins project and consider mitigating controls until a fix is applied.

For European organizations, this vulnerability poses a substantial risk, especially for those relying on Jenkins for software development and deployment workflows. An attacker exploiting this flaw could leverage minimal permissions to initiate unauthorized connections to attacker-controlled servers, potentially exfiltrating sensitive build or configuration data, injecting malicious payloads, or disrupting CI/CD processes. This could lead to compromised software integrity, unauthorized access to internal networks, or service outages. Given the critical role of Jenkins in automating software pipelines, exploitation could cascade into broader operational disruptions. Organizations in sectors with stringent regulatory requirements (e.g., finance, healthcare, critical infrastructure) may face compliance violations and reputational damage if this vulnerability is exploited. Additionally, the ease of exploitation and high impact on confidentiality, integrity, and availability make this a pressing concern for European enterprises aiming to maintain secure and reliable development environments.

1. Immediate verification of the Jenkins NS-ND Integration Performance Publisher Plugin version in use and upgrade to the latest version once a patch is released by the Jenkins project. 2. Until a patch is available, restrict Overall/Read permissions strictly to trusted users only, minimizing the attack surface. 3. Implement network-level controls to monitor and restrict outbound connections from Jenkins servers, preventing unauthorized connections to external attacker-controlled servers. 4. Employ application-layer firewalls or proxy solutions that can detect and block suspicious traffic originating from Jenkins instances. 5. Conduct regular audits of Jenkins user permissions and plugin usage to ensure adherence to the principle of least privilege. 6. Monitor Jenkins logs for unusual connection attempts or authentication activities that could indicate exploitation attempts. 7. Consider isolating Jenkins servers within segmented network zones with limited external connectivity to reduce exposure. 8. Stay informed through Jenkins security advisories and subscribe to vulnerability notification services to respond promptly to updates.
