Moderate severity GitHub Reviewed Published Oct 19, 2022 to the GitHub Advisory Database • Updated Jan 4, 2024

Package

maven com.compuware.jenkins:compuware-scm-downloader (Maven)

Affected versions

< 2.0.13

Patched versions

2.0.13

Description

BMC Compuware Source Code Download for Endevor, PDS, and ISPW Plugin 2.0.12 and earlier implements an agent/controller message that does not limit where it can be executed.

It allows attackers able to control agent processes to obtain the values of Java system properties from the Jenkins controller process.

This vulnerability is only exploitable in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier. See the LTS upgrade guide.

BMC Compuware Source Code Download for Endevor, PDS, and ISPW Plugin 2.0.13 restricts execution of the agent/controller message to agents.

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.
