Background
The useMango Runner Plugin is a Maven package that is used in Jenkins, an open-source automation server. This plugin allows users to run tests and validate forms using the useMango service. It provides a convenient way to integrate useMango functionality into Jenkins workflows. The useMango service is responsible for providing values for form validation endpoints. However, versions 1.4 and earlier of the useMango Runner Plugin do not properly escape the values received from the useMango service, leading to a cross-site scripting (XSS) vulnerability. This vulnerability can be exploited by users who can control the values returned from the useMango service.
Vulnerability Detail
The XSS vulnerability in the useMango Runner Plugin arises from the lack of proper value escaping in form validation endpoints. When users are able to control the values returned from the useMango service, they can inject malicious scripts into the form validation messages. This can lead to the execution of arbitrary code in the context of other users who view the affected form validation messages. The impact of this vulnerability can range from unauthorized access to sensitive information to complete system compromise. The vulnerability has been assigned a CVSS score of 5.4, indicating a moderate severity level.
