High severity GitHub Reviewed Published Jan 21, 2022 to the GitHub Advisory Database • Updated Oct 27, 2023

Package

maven io.jenkins.plugins:warnings-ng (Maven)

Affected versions

>= 9.8.0, < 9.10.3
>= 9.6.0, < 9.7.1
>= 9.1.0, < 9.5.2

Description

Jenkins Warnings Next Generation Plugin prior to 9.10.3, 9.7.1, 9.5.2, and 9.0.2 does not restrict the name of a file when configuring a custom ID.

This allows attackers with Item/Configure permission to write and read specific files with a hard-coded suffix on the Jenkins controller file system.

Jenkins Warnings Next Generation Plugin 9.10.3, 9.7.1, 9.5.2, and 9.0.2 checks for the presence of prohibited directory separator characters in the custom ID.

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.
