CVE-2022-41248 is a medium-severity vulnerability affecting the Jenkins BigPanda Notifier Plugin version 1.4.0 and earlier. The vulnerability arises because the plugin does not mask the BigPanda API key on the global configuration form within Jenkins. This means that the API key, which is a sensitive credential used to authenticate and send notifications to the BigPanda incident management platform, is displayed in clear text. An attacker with access to the Jenkins interface or configuration files could observe and capture this API key. The vulnerability is classified under CWE-312 (Cleartext Storage of Sensitive Information) and has a CVSS v3.1 base score of 5.3, indicating a medium impact. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact is limited to confidentiality (C:L), with no impact on integrity or availability. No known exploits are currently reported in the wild. The lack of masking increases the risk of credential leakage, which could allow an attacker to impersonate the Jenkins instance to BigPanda, potentially manipulating incident notifications or gaining further insight into incident management processes. However, exploitation requires access to the Jenkins global configuration interface or configuration files, which typically requires some level of access to the Jenkins environment.

For European organizations, this vulnerability poses a risk primarily to the confidentiality of sensitive API credentials used in their CI/CD pipelines if they use Jenkins with the BigPanda Notifier Plugin. Exposure of the BigPanda API key could allow attackers to intercept or forge incident notifications, potentially misleading incident response teams or masking real security events. This could degrade the effectiveness of security operations and incident management. While the vulnerability does not directly impact system integrity or availability, the indirect effects on incident response could increase the risk of prolonged or undetected security incidents. Organizations with strict data protection regulations, such as GDPR, must consider the potential compliance implications of credential exposure. Additionally, organizations relying heavily on automated incident management and notification workflows may experience operational disruptions if attackers manipulate notification data. The risk is heightened in environments where Jenkins is accessible to multiple users or where access controls are insufficiently restrictive.

To mitigate this vulnerability, European organizations should immediately upgrade the Jenkins BigPanda Notifier Plugin to a version where the API key is properly masked in the global configuration form, if such an update is available. If no patch is available, organizations should restrict access to the Jenkins global configuration page strictly to trusted administrators and audit access logs for any unauthorized access attempts. Additionally, rotate the BigPanda API keys to invalidate any potentially exposed credentials. Implement role-based access control (RBAC) and enforce the principle of least privilege for Jenkins users. Use Jenkins security best practices, such as enabling CSRF protection, securing Jenkins with HTTPS, and integrating with centralized authentication systems (e.g., LDAP, SAML). Regularly review and monitor Jenkins plugin configurations and credentials storage. Consider using secret management tools or Jenkins credentials plugins that securely store and mask sensitive information. Finally, conduct security awareness training for administrators to recognize the importance of protecting API keys and other credentials within CI/CD tools.
