CVE-2022-43424 in Code Coverage Plugin
Summary
by MITRE • 10/19/2022
Jenkins Compuware Xpediter Code Coverage Plugin 1.0.7 and earlier implements an agent/controller message that does not limit where it can be executed, allowing attackers able to control agent processes to obtain the values of Java system properties from the Jenkins controller process.

The vulnerability identified as CVE-2022-43424 affects the Jenkins Compuware Xpediter Code Coverage Plugin version 1.0.7 and earlier, presenting a significant security risk within continuous integration and deployment environments. This issue stems from improper message handling within the plugin's agent/controller communication mechanism, which fails to enforce proper execution boundaries. The flaw allows malicious actors who have compromised agent processes to extract sensitive Java system properties from the Jenkins controller, potentially exposing critical system information that could facilitate further attacks.
The technical implementation of this vulnerability resides in the plugin's message processing logic where it fails to validate or restrict the execution context of received messages. When an attacker gains control of a Jenkins agent process, they can leverage this weakness to send specially crafted messages that bypass normal security boundaries. The system properties extracted from the controller process may include sensitive information such as file paths, Java version details, memory configurations, and potentially other system-level parameters that could aid in crafting more sophisticated attacks. This represents a privilege escalation vulnerability where local control of an agent translates to remote information disclosure on the controller.
The operational impact of CVE-2022-43424 extends beyond simple information disclosure, as the extracted system properties can serve as valuable intelligence for attackers planning subsequent exploitation attempts. The vulnerability aligns with CWE-200 (Information Exposure) and can be categorized under ATT&CK technique T1082 (System Information Discovery) and T1552 (Unsecured Credentials). Organizations running Jenkins with this plugin version face elevated risk of credential theft, system reconnaissance, and potential lateral movement within their infrastructure. The vulnerability is particularly concerning in enterprise environments where Jenkins controllers often maintain elevated privileges and access to sensitive resources.
Mitigation strategies for this vulnerability require immediate plugin version updates to 1.0.8 or later, which includes proper message execution boundary controls. Organizations should also implement network segmentation to limit agent-controller communication to trusted networks and consider implementing additional monitoring for unusual message patterns. The fix addresses the root cause by enforcing proper validation of message origins and execution contexts, preventing unauthorized access to controller system properties. Security teams should conduct comprehensive vulnerability assessments to identify all instances of this plugin version and ensure proper patch management procedures are in place to prevent similar issues in other Jenkins plugins.
