This vulnerability exists within the Jenkins Compuware Source Code Download for Endevor PDS and ISPW plugin version 2.0.12 and earlier, representing a critical authorization flaw that undermines the security posture of Jenkins environments. The issue stems from a missing permission check that allows unauthorized users with only Overall/Read permission to access sensitive configuration information. This weakness falls under the category of insufficient authorization checks, which is classified as CWE-285 in the Common Weakness Enumeration framework. The vulnerability represents a significant bypass of Jenkins' access control mechanisms, as it enables attackers to enumerate host and port information for Compuware configurations and extract credential IDs from Jenkins' credential store.
The technical implementation of this flaw occurs within the plugin's API endpoints or internal methods that handle Compuware configuration data retrieval. Attackers can exploit this by leveraging their Overall/Read permission to make specific requests that should normally be restricted to users with higher privileges or administrative access. The enumeration process allows threat actors to discover network endpoints, service ports, and credential identifiers that are typically protected within Jenkins' security architecture. This information can then be used to plan more sophisticated attacks against the Compuware systems or to target the specific credential IDs for credential theft or manipulation. The vulnerability essentially creates a backdoor pathway that exposes configuration metadata to users who should not have access to such information.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with critical reconnaissance data that can be leveraged for further compromise. Once an attacker has enumerated the host and port information, they can potentially conduct network scanning or direct attacks against the discovered Compuware systems. The exposure of credential IDs within Jenkins' credential store creates additional attack vectors for credential harvesting, which could lead to unauthorized access to production systems, databases, or other sensitive infrastructure. This vulnerability particularly affects organizations that rely heavily on Compuware tools for mainframe application management and development, as the exposed information could provide attackers with access to critical enterprise systems. The impact is compounded by the fact that this vulnerability affects a widely used Jenkins plugin, making it a potential target for automated exploitation campaigns.
Organizations should immediately upgrade to the patched version of the Jenkins Compuware Source Code Download for Endevor PDS and ISPW plugin to address this vulnerability. The recommended mitigation strategy includes implementing the latest plugin version that contains the proper permission checks and access controls. Security teams should also review existing access controls and ensure that users with Overall/Read permission do not have unnecessary access to configuration information. Additionally, implementing network segmentation and monitoring for unusual enumeration patterns can help detect potential exploitation attempts. From an ATT&CK framework perspective, this vulnerability maps to techniques related to credential access and reconnaissance, specifically covering T1552 (Credentials from Password Stores) and T1082 (System Information Discovery). Organizations should also consider implementing principle of least privilege access controls and regular security audits of Jenkins plugins to prevent similar issues in the future. The vulnerability highlights the importance of thorough security testing of plugin components and proper authorization validation within continuous integration and deployment environments.
