CVE-2025-53672: Vulnerability in Jenkins Project Jenkins Kryptowire Plugin
Jenkins Kryptowire Plugin 0.2 and earlier stores the Kryptowire API key unencrypted in its global configuration file on the Jenkins controller, where it can be viewed by users with access to the Jenkins controller file system.
AI Analysis
Technical Summary
CVE-2025-53672 is a security vulnerability identified in the Jenkins Kryptowire Plugin version 0.2 and earlier. The vulnerability arises because the plugin stores the Kryptowire API key in plaintext within the global configuration file on the Jenkins controller. This configuration file is accessible to users who have file system access to the Jenkins controller. Since the API key is unencrypted, any user with such access can view and potentially misuse the key. The Kryptowire API key likely grants access to sensitive functionalities or data related to the Kryptowire service integrated with Jenkins. The exposure of this key can lead to unauthorized access or manipulation of the service, potentially compromising the confidentiality and integrity of the data or operations managed through the plugin. The vulnerability does not require user interaction to be exploited but does require access to the Jenkins controller file system, which is typically restricted to administrators or privileged users. No known exploits are currently reported in the wild, and no CVSS score has been assigned yet. However, the risk remains significant due to the sensitive nature of API keys and the potential for privilege escalation or lateral movement within an environment if the key is compromised.
Potential Impact
For European organizations, this vulnerability poses a risk primarily to those using Jenkins with the Kryptowire Plugin in their CI/CD pipelines or software development environments. Exposure of the API key could allow attackers or malicious insiders to access or manipulate the Kryptowire service, potentially leading to unauthorized data access, data leakage, or disruption of automated workflows. Given Jenkins' widespread use in software development across Europe, organizations in sectors such as finance, healthcare, telecommunications, and government could be particularly impacted due to the sensitive nature of their data and regulatory requirements like GDPR. The compromise of the API key could also facilitate further attacks within the network, including lateral movement or privilege escalation, especially if Jenkins controllers are not adequately segmented or secured. This could lead to broader operational disruptions and compliance violations, resulting in financial and reputational damage.
Mitigation Recommendations
To mitigate this vulnerability, organizations should immediately upgrade the Jenkins Kryptowire Plugin to a version that encrypts the API key or implements secure storage mechanisms once such a patch is released. Until then, restrict file system access to the Jenkins controller strictly to trusted administrators and audit access logs regularly. Implement strong access controls and segmentation to limit who can reach the Jenkins controller file system. Consider rotating the Kryptowire API key to invalidate any potentially exposed keys. Additionally, monitor Jenkins logs and network traffic for any unusual activity that might indicate misuse of the API key. Employ secrets management solutions integrated with Jenkins to avoid storing sensitive keys in plaintext configuration files. Finally, ensure that Jenkins instances are regularly updated and that security best practices for CI/CD environments are followed to reduce the attack surface.
