CVE-2025-53670 is a vulnerability identified in the Jenkins Nouvola DiveCloud Plugin version 1.08 and earlier. The core issue is the insecure storage of sensitive credentials—specifically DiveCloud API Keys and Credentials Encryption Keys—in plaintext within job config.xml files on the Jenkins controller. These config files are typically accessible to users with Item or Extended Read permissions within Jenkins or to anyone with direct access to the Jenkins controller's file system. Because the credentials are stored unencrypted, an attacker or unauthorized user with these access levels can easily extract them, leading to a compromise of the DiveCloud API and potentially other integrated systems. The vulnerability is classified under CWE-312 (Cleartext Storage of Sensitive Information) and has a CVSS v3.1 base score of 6.5, indicating a medium severity. The attack vector is network-based (AV:N), requires low privileges (PR:L), and no user interaction (UI:N). The impact is primarily on confidentiality (C:H), with no direct effect on integrity or availability. No patches have been released at the time of publication, and no exploits have been observed in the wild. This vulnerability highlights the risk of improper credential management in CI/CD environments and the importance of securing Jenkins plugins and their configuration data.

For European organizations, this vulnerability poses a significant risk to the confidentiality of sensitive API keys used in automation and deployment pipelines. Exposure of DiveCloud API Keys can lead to unauthorized access to cloud resources or services integrated via DiveCloud, potentially resulting in data leakage, unauthorized modifications, or further lateral movement within the network. Since Jenkins is widely used across European enterprises for continuous integration and deployment, especially in technology, finance, and manufacturing sectors, the risk is amplified where multiple users have read access or where Jenkins controllers are not adequately secured at the file system level. The breach of credentials could also undermine compliance with GDPR and other data protection regulations due to unauthorized access to sensitive operational data. Although the vulnerability does not directly affect system integrity or availability, the indirect consequences of credential compromise can be severe, including disruption of automated workflows and potential exposure of proprietary or customer data.

In the absence of an official patch, European organizations should implement immediate compensating controls. First, restrict Jenkins user permissions to the minimum necessary, particularly limiting Item and Extended Read permissions to trusted users only. Second, enforce strict file system access controls on the Jenkins controller to prevent unauthorized users from reading config.xml files. Third, consider encrypting sensitive credentials outside Jenkins or using Jenkins credentials plugins that securely store secrets instead of embedding them in job configurations. Fourth, audit existing Jenkins jobs to identify and remove any plaintext API keys stored in config.xml files. Fifth, monitor Jenkins logs and access patterns for unusual activity that might indicate attempts to access sensitive files. Finally, stay alert for updates from the Jenkins project and apply patches promptly once available. Organizations should also review their incident response plans to handle potential credential compromise scenarios.
