The vulnerability identified as CVE-2025-53671 affects the Jenkins Nouvola DiveCloud Plugin version 1.08 and earlier. The core issue is that the plugin fails to mask sensitive DiveCloud API Keys and Credentials Encryption Keys when displayed on the job configuration form within Jenkins. This means that any user with access to configure Jenkins jobs can view these sensitive credentials in plaintext, which should normally be obfuscated or masked to prevent exposure. The vulnerability is categorized under CWE-256 (Plaintext Storage of a Password) and CWE-522 (Insufficiently Protected Credentials). The CVSS v3.1 base score is 6.5 (medium severity), with an attack vector of network (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). The vulnerability does not require user interaction but does require the attacker to have at least low privileges to access job configuration forms. There are no known exploits in the wild at this time, and no patches have been released yet. The exposure of API keys and encryption keys can lead to unauthorized access to DiveCloud services and potentially broader compromise if these credentials are reused or provide elevated access. The vulnerability highlights a failure in secure credential handling within the plugin's UI, increasing the risk of insider threats or lateral movement within Jenkins environments.

For European organizations, this vulnerability poses a significant confidentiality risk, especially in environments where multiple users have job configuration permissions in Jenkins. Exposure of DiveCloud API keys and encryption keys can lead to unauthorized access to cloud resources, potentially resulting in data breaches or service disruptions. Organizations relying on Jenkins for continuous integration and deployment may face increased risk of credential theft, which could be leveraged for further attacks such as privilege escalation or lateral movement. The impact is heightened in sectors with stringent data protection requirements like finance, healthcare, and critical infrastructure. Since the vulnerability does not affect integrity or availability directly, the primary concern is unauthorized data access and potential misuse of credentials. The lack of masking also increases the risk from insider threats or accidental exposure during routine configuration reviews. The absence of patches means organizations must rely on access controls and monitoring to mitigate risk in the short term.

1. Restrict Jenkins job configuration access strictly to trusted and necessary personnel to minimize exposure to sensitive credentials. 2. Implement role-based access control (RBAC) and audit permissions regularly to ensure least privilege principles are enforced. 3. Monitor Jenkins logs and job configuration changes for unusual activity that could indicate credential harvesting attempts. 4. Avoid storing sensitive API keys and encryption keys directly in Jenkins job configurations; use Jenkins credentials store or external secret management solutions that mask or encrypt secrets properly. 5. Educate Jenkins administrators and users about the risks of credential exposure and encourage secure handling practices. 6. Apply network segmentation and multi-factor authentication (MFA) to Jenkins access to reduce risk of unauthorized access. 7. Stay alert for official patches or updates from the Jenkins project and apply them promptly once available. 8. Consider temporary disabling or replacing the Nouvola DiveCloud Plugin if feasible until a fix is released. 9. Conduct regular security assessments of CI/CD pipelines to identify and remediate similar credential exposure risks.
