Agent-to-controller security bypass in Jenkins BMC Compuware ISPW Operations plugin

Moderate severity GitHub Reviewed Published Jul 28, 2022 to the GitHub Advisory Database • Updated Feb 2, 2023

Package

maven com.compuware.jenkins:compuware-ispw-operations (Maven)

Affected versions

<= 1.0.8

Patched versions

1.0.9

Description

BMC Compuware ISPW Operations Plugin defines a controller/agent message that retrieves Java system properties. BMC Compuware ISPW Operations Plugin 1.0.8 and earlier does not restrict execution of the controller/agent message to agents. This allows attackers able to control agent processes to retrieve Java system properties. This vulnerability is only exploitable in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier. See the LTS upgrade guide. BMC Compuware ISPW Operations plugin 1.0.9 does not allow the affected controller/agent message to be submitted by agents for execution on the controller.

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.
