Incorrect permission check in XebiaLabs XL Deploy Plugin allows capturing credentials

Moderate severity GitHub Reviewed Published May 24, 2022 to the GitHub Advisory Database • Updated Dec 21, 2023

Package

maven com.xebialabs.deployit.ci:deployit-plugin (Maven)

Affected versions

<= 10.0.1

Patched versions

10.0.2

Description

An incorrect permission check in Jenkins XebiaLabs XL Deploy Plugin 10.0.1 and earlier allows attackers with Generic Create permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing Username/password credentials stored in Jenkins.

The permission check was partially fixed in XebiaLabs XL Deploy Plugin 7.5.9: A permission check was added, but for the wrong permission, still allowing some non-admin users to access the form validation method.

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.
