Credentials transmitted in plain text by Repository Connector Plugin

Low severity GitHub Reviewed Published May 24, 2022 to the GitHub Advisory Database • Updated Jan 30, 2023

Package

maven org.jenkins-ci.plugins:repository-connector (Maven)

Affected versions

<= 1.2.6

Patched versions

2.0.0

Description

Repository Connector Plugin stores credentials in its global configuration file org.jvnet.hudson.plugins.repositoryconnector.RepositoryConfiguration.xml on the Jenkins controller as part of its configuration.

While the credentials are stored encrypted on disk, they are transmitted in plain text as part of the configuration form by Repository Connector Plugin 1.2.6 and earlier. This can result in exposure of the credential through browser extensions, cross-site scripting vulnerabilities, and similar situations.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
