Published: 2017-11-21 · updated 2026-06-17
Weakness: CWE-532

Description

A flaw was found in the way Ansible (2.3.x before 2.3.3, and 2.4.x before 2.4.1) passed certain parameters to the jenkins_plugin module. Remote attackers could use this flaw to expose sensitive information from a remote host's logs. This flaw was fixed by not allowing passwords to be specified in the "params" argument, and noting this in the module documentation.

Affected products

Red Hat Ansible: from 2.3.0 before 2.3.3; from 2.4.0 before 2.4.1 — fixed in 2.3.3, 2.4.1
RedHat Enterprise Linux Server: 7.0

How to fix

Upgrade to a fixed version: Red Hat Ansible 2.3.3, 2.4.1. Check the vendor advisory for mitigations.
