Client secret transmitted in plain text by Azure AD Plugin

Low severity GitHub Reviewed Published May 24, 2022 to the GitHub Advisory Database • Updated Oct 26, 2023

Package

maven org.jenkins-ci.plugins:azure-ad (Maven)

Affected versions

< 1.2.0

Patched versions

1.2.0

Description

Azure AD Plugin stores a client secret in its global configuration.

While the credential is stored encrypted on disk, it is transmitted in plain text as part of the configuration form by Azure AD Plugin 1.1.2 and earlier. This can result in exposure of the credential through browser extensions, cross-site scripting vulnerabilities, and similar situations.

Azure AD Plugin 1.2.0 transmits the client secret in its global configuration encrypted.

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.
