RCE vulnerability in Jenkins Code Coverage API Plugin

High severity GitHub Reviewed Published May 24, 2022 to the GitHub Advisory Database • Updated Dec 15, 2023

Package

maven io.jenkins.plugins:code-coverage-api (Maven)

Affected versions

<= 1.4.0

Patched versions

1.4.1

Description

Jenkins Code Coverage API Plugin 1.4.0 and earlier does not apply JEP-200 deserialization protection to Java objects it deserializes from disk.

This results in a remote code execution (RCE) vulnerability exploitable by attackers able to control agent processes.

Jenkins Code Coverage API Plugin 1.4.1 configures its Java object deserialization to only deserialize safe types.

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.
