Cross-site Scripting in Jenkins Validating Email Parameter Plugin

High severity GitHub Reviewed Published Jul 1, 2022 to the GitHub Advisory Database • Updated Jan 28, 2023

Package

maven io.jenkins.plugins:validating-email-parameter (Maven)

Affected versions

<= 1.10

Patched versions

None

Description

Jenkins Validating Email Parameter Plugin 1.10 and earlier does not escape the name and description of its parameter type.

Additionally, it disables the security hardening added in Jenkins 2.44 and LTS 2.32.2 as part of the SECURITY-353 / CVE-2017-2601 fix that protects the "Build With Parameters" and "Parameters" pages from vulnerabilities like this by default.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.

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.
