Jenkins vSphere Plugin incorrect authorization vulnerability

Moderate severity GitHub Reviewed Published May 13, 2022 to the GitHub Advisory Database • Updated Feb 1, 2023

Package

maven org.jenkins-ci.plugins:vsphere-cloud (Maven)

Affected versions

<= 2.16

Patched versions

2.17

Description

An improper authorization vulnerability exists in Jenkins vSphere Plugin 2.16 and older in Clone.java, CloudSelectorParameter.java, ConvertToTemplate.java, ConvertToVm.java, Delete.java, DeleteSnapshot.java, Deploy.java, ExposeGuestInfo.java, FolderVSphereCloudProperty.java, PowerOff.java, PowerOn.java, Reconfigure.java, Rename.java, RenameSnapshot.java, RevertToSnapshot.java, SuspendVm.java, TakeSnapshot.java, VSphereBuildStepContainer.java, vSphereCloudProvisionedSlave.java, vSphereCloudSlave.java, vSphereCloudSlaveTemplate.java, VSphereConnectionConfig.java, vSphereStep.java that allows attackers to perform form validation related actions, including sending numerous requests to the configured vSphere server, potentially resulting in denial of service, or send credentials stored in Jenkins with known ID to an attacker-specified server ("test connection"). As of version 2.17, these form validation methods require POST requests and appropriate user permissions.

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.
