The vulnerability identified as CVE-2022-28137 resides within the Jenkins JiraTestResultReporter Plugin, specifically affecting versions up to and including 165.v817928553942. This issue represents a critical authorization bypass flaw that undermines the security model of the Jenkins continuous integration platform. The vulnerability manifests as a missing permission check that allows authenticated users with only Overall/Read permission to execute unauthorized network operations against arbitrary endpoints. This misconfiguration creates a pathway for attackers to leverage their limited access privileges to perform actions beyond their intended scope, effectively weakening the permission boundaries that protect sensitive system resources.
The technical implementation of this vulnerability stems from insufficient validation within the plugin's URL connection handling mechanism. When the JiraTestResultReporter plugin processes test results and attempts to communicate with Jira servers, it fails to properly verify whether the authenticated user possesses adequate permissions to initiate connections to external systems. This oversight enables an attacker with minimal privileges to specify arbitrary URLs and provide custom authentication credentials that the system will attempt to use for network communication. The flaw operates at the application layer and can be exploited through the Jenkins web interface or API endpoints that trigger the plugin functionality.
Operationally, this vulnerability presents significant risks to organizations utilizing Jenkins with the affected plugin. Attackers can exploit this weakness to perform reconnaissance activities against internal systems, potentially accessing sensitive resources that would normally be restricted. The impact extends beyond simple information disclosure, as attackers may be able to exfiltrate data, inject malicious payloads, or establish command and control channels through the compromised connection mechanism. The vulnerability also facilitates potential lateral movement within network environments, especially when Jenkins servers maintain access to internal resources or services that are not properly isolated from external threats.
Organizations should immediately upgrade to the patched version of the JiraTestResultReporter plugin to remediate this vulnerability. In the interim, administrators should implement network-level restrictions to limit outbound connectivity from Jenkins servers, particularly blocking access to sensitive internal endpoints. The vulnerability aligns with CWE-693 Permission Bug, which specifically addresses inadequate permission checking mechanisms in software applications. From an ATT&CK framework perspective, this vulnerability maps to techniques involving privilege escalation and lateral movement, as it allows attackers to perform actions that would normally require higher privileges. Security teams should also consider implementing additional monitoring for unusual outbound network connections originating from Jenkins servers, as this could serve as an indicator of exploitation attempts. The remediation process should include thorough access control reviews to ensure that users with Overall/Read permissions are not granted unnecessary capabilities that could be exploited for unauthorized network operations.
