Why these techniques?

Vulnerability enables remote exploitation of a public-facing Jenkins library component for sensitive data disclosure via flawed timing attack mitigation.

Confidence: MEDIUM · MITRE ATT&CK Enterprise v18.1

NVD Description

Jervis is a library for Job DSL plugin scripts and shared Jenkins pipeline libraries. Prior to 2.2, Jervis uses java.util.Random() which is not cryptographically secure for timing attack mitigation. This vulnerability is fixed in 2.2.

Deeper analysisAI

CVE-2025-68704 affects Jervis, a library used for Job DSL plugin scripts and shared Jenkins pipeline libraries. In versions prior to 2.2, Jervis relies on java.util.Random(), which is not cryptographically secure, for timing attack mitigation. This flaw, classified under CWE-330 (Use of Insufficiently Random Values), carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high confidentiality impact with no requirements for privileges or user interaction.

Remote attackers can exploit this vulnerability over the network with low complexity. By leveraging the predictable randomness from java.util.Random(), adversaries may conduct timing attacks to infer sensitive information processed or protected by Jervis in Jenkins environments, potentially disclosing confidential data without impacting integrity or availability.

The vulnerability is addressed in Jervis version 2.2, where the insecure random number generator is replaced. Security practitioners should upgrade to 2.2 or later, as detailed in the GitHub security advisory (GHSA-c9q6-g3hr-8gww) and the fixing commit (c3981ff71de7b0f767dfe7b37a2372cb2a51974a).
