Jenkins SAML Single Sign On(SSO) Plugin missing permission check

Moderate severity GitHub Reviewed Published Jul 12, 2023 to the GitHub Advisory Database • Updated Nov 7, 2023

Package

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

Affected versions

< 2.3.1

Patched versions

2.3.1

Description

Jenkins SAML Single Sign On(SSO) Plugin 2.3.0 and earlier does not perform a permission check in an HTTP endpoint.

This allows attackers with Overall/Read permission to download a string representation of the current security realm (Java Object#toString()), which potentially includes sensitive information.

SAML Single Sign On(SSO) Plugin 2.3.1 requires Overall/Administer permission to access the affected HTTP endpoint, and only allows downloading a string representation if the current security realm is this plugin’s.

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.
