Summary
by MITRE • 07/27/2022
A missing permission check in Jenkins Compuware Topaz Utilities Plugin 1.0.8 and earlier allows attackers with Overall/Read permission to enumerate hosts and ports of Compuware configurations and credentials IDs of credentials stored in Jenkins.

The vulnerability identified as CVE-2022-36895 represents a critical authorization flaw within the Jenkins Compuware Topaz Utilities Plugin version 1.0.8 and earlier. This issue stems from a missing permission check that fundamentally undermines the security model of the plugin by allowing unauthorized access to sensitive configuration information. The vulnerability exists at the core of Jenkins' permission system where proper access controls should be enforced but are instead bypassed, creating a significant risk for organizations relying on this plugin for their automation infrastructure.
The technical flaw manifests as an insufficient validation mechanism that fails to verify whether authenticated users possess the appropriate privileges before exposing sensitive data. Specifically, attackers with only Overall/Read permission can enumerate host and port information from Compuware configurations, along with credentials IDs from Jenkins' credential store. This represents a classic case of insufficient authorization checks that violates fundamental security principles and creates a pathway for information disclosure attacks. The vulnerability operates at the application layer and directly impacts Jenkins' security model by allowing privilege escalation through data enumeration rather than direct execution or modification.
The operational impact of this vulnerability is substantial as it provides attackers with reconnaissance capabilities that can be leveraged for more sophisticated attacks. Once an attacker obtains the enumerated host and port information, they can potentially target these systems with further exploitation attempts, while access to credential IDs enables them to attempt credential harvesting or brute force attacks against the identified systems. This vulnerability particularly affects organizations using Jenkins for continuous integration and deployment workflows where Compuware tools are integrated, potentially compromising the entire CI/CD pipeline security posture. The impact extends beyond immediate information disclosure to include potential system compromise and data breach scenarios.
Organizations should immediately update to the patched version of the Jenkins Compuware Topaz Utilities Plugin to remediate this vulnerability, as no effective workarounds exist for this specific authorization flaw. The recommended mitigation strategy involves implementing proper access controls and ensuring that Jenkins administrators regularly audit plugin permissions and update all components to their latest secure versions. Security teams should also monitor for any unauthorized access attempts or enumeration activities in their Jenkins logs and implement network-level restrictions to limit exposure. This vulnerability aligns with CWE-693 which addresses protection mechanism failures and represents a clear violation of the principle of least privilege that should be enforced across all Jenkins plugins and components. The issue also maps to ATT&CK technique T1087.001 for account discovery and T1552.001 for credentials in files, as attackers can use the enumerated information to further compromise systems. Organizations should conduct comprehensive security assessments of their Jenkins environments to identify any other plugins or components that may be susceptible to similar authorization bypass vulnerabilities.
