Jenkins SAML Single Sign On(SSO) Plugin missing hostname validation

Moderate severity GitHub Reviewed Published May 16, 2023 to the GitHub Advisory Database • Updated Nov 8, 2023

Package

maven io.jenkins.plugins:miniorange-saml-sp (Maven)

Affected versions

< 2.1.0

Patched versions

2.1.0

Description

Jenkins SAML Single Sign On(SSO) Plugin 2.0.2 and earlier does not perform hostname validation when connecting to miniOrange or the configured IdP to retrieve SAML metadata.

This lack of validation could be abused using a man-in-the-middle attack to intercept these connections.

SAML Single Sign On(SSO) Plugin 2.1.0 performs hostname validation when connecting to miniOrange or the configured IdP to retrieve SAML metadata.

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.
