CVE-2022-41247 is a medium-severity vulnerability affecting the Jenkins BigPanda Notifier Plugin version 1.4.0 and earlier. This plugin integrates Jenkins with BigPanda, a platform used for incident management and alert correlation. The vulnerability arises because the plugin stores the BigPanda API key unencrypted in the global configuration file on the Jenkins controller. This file is accessible to any user who has file system access to the Jenkins controller machine. The exposure of the API key can lead to unauthorized access to the BigPanda service, potentially allowing an attacker to manipulate or view incident data, inject false alerts, or disrupt alerting workflows. The vulnerability is classified under CWE-522 (Insufficiently Protected Credentials). The CVSS 3.1 base score is 4.3 (medium), reflecting that the attack vector is network-based (AV:N), requires low attack complexity (AC:L), but requires privileges (PR:L) on the Jenkins controller and no user interaction (UI:N). The impact is limited to confidentiality (C:L) with no impact on integrity or availability. There are no known exploits in the wild, and no patches are explicitly linked in the provided data, so mitigation may rely on configuration changes or plugin updates from the vendor. The vulnerability does not allow remote unauthenticated attackers to directly compromise Jenkins or BigPanda but poses a risk if an attacker gains low-level access to the Jenkins controller file system, such as through compromised credentials or other vulnerabilities.

For European organizations using Jenkins with the BigPanda Notifier Plugin, this vulnerability could lead to unauthorized disclosure of the BigPanda API key if an attacker gains access to the Jenkins controller file system. This could compromise incident management workflows by allowing attackers to view sensitive alert data or inject misleading alerts, potentially delaying or disrupting incident response. While the vulnerability does not directly compromise Jenkins or the underlying infrastructure, it weakens the security posture of the incident management process. Organizations in regulated sectors such as finance, healthcare, or critical infrastructure in Europe could face compliance risks if incident data confidentiality is breached. Additionally, disruption or manipulation of alerting could increase the risk of undetected security incidents or operational outages. The medium severity and requirement for some privilege on the Jenkins controller mean that the threat is more relevant in environments where Jenkins access controls are weak or where attackers have already gained some foothold.

European organizations should immediately audit access controls on Jenkins controllers to ensure that only trusted administrators have file system access. Restricting access to the Jenkins home directory and configuration files is critical. Organizations should upgrade the Jenkins BigPanda Notifier Plugin to the latest version if a patched release is available from the Jenkins project or BigPanda. If no patch exists, consider removing or disabling the plugin until a fix is released. Additionally, rotate the BigPanda API keys used by Jenkins to invalidate any potentially exposed credentials. Implement monitoring and alerting for unusual access patterns to the Jenkins controller file system and for suspicious API activity in BigPanda. Employ secrets management solutions that avoid storing API keys in plaintext configuration files. Finally, conduct regular security reviews of Jenkins plugins and configurations to detect similar issues proactively.
