CSRF vulnerability in Amazon EC2 Plugin

Low severity GitHub Reviewed Published May 24, 2022 to the GitHub Advisory Database • Updated Dec 20, 2023

Package

maven org.jenkins-ci.plugins:ec2 (Maven)

Affected versions

<= 1.50.1

Patched versions

1.50.2

Description

Amazon EC2 Plugin 1.50.1 and earlier does not require POST requests in several HTTP endpoints, resulting in cross-site request forgery (CSRF) vulnerabilities. This allows an attacker to provision instances with an attacker-specified template ID.

Amazon EC2 Plugin 1.50.2 now requires POST requests for the affected HTTP endpoints.

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.
