High severity GitHub Reviewed Published Nov 16, 2022 to the GitHub Advisory Database • Updated Jan 31, 2023

Package

maven org.jvnet.hudson.plugins:japex (Maven)

Affected versions

<= 1.7

Patched versions

None

Description

JAPEX Plugin 1.7 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers able to control XML input files for the 'Record Japex test report' post-build step to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

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.
