CVE-2024-29201 in JumpServer
Summary
by MITRE • 03/29/2024
JumpServer is an open source bastion host and an operation and maintenance security audit system. Attackers can bypass the input validation mechanism in JumpServer's Ansible to execute arbitrary code within the Celery container. Since the Celery container runs with root privileges and has database access, attackers could steal sensitive information from all hosts or manipulate the database. This vulnerability is fixed in v3.10.7.

The vulnerability identified as CVE-2024-29201 affects JumpServer, an open source bastion host and operation and maintenance security audit system that serves as a centralized access control and audit solution for enterprise environments. This system provides critical security functions including privileged access management, session recording, and audit trails for administrative activities across network infrastructure. The vulnerability resides within JumpServer's Ansible integration component, specifically targeting the input validation mechanisms that are designed to prevent unauthorized code execution and maintain system integrity. The flaw represents a significant security weakness in a system that is specifically built to protect enterprise environments from unauthorized access and malicious activities.
The technical implementation of this vulnerability stems from inadequate input validation within the Ansible execution pathway of JumpServer's Celery container architecture. When JumpServer processes Ansible playbooks or commands, it fails to properly validate user-supplied input parameters that are passed to the underlying Celery task execution engine. This validation bypass allows attackers to inject malicious payloads that can execute arbitrary code within the Celery container context. The vulnerability is particularly dangerous because the Celery container operates with root privileges, providing attackers with elevated system access that extends beyond typical user limitations. This privilege escalation occurs without proper sanitization of input parameters, creating a direct pathway for code injection attacks that can leverage the container's full system capabilities.
The operational impact of this vulnerability extends far beyond simple code execution, as the affected Celery container maintains database access permissions that enable attackers to access sensitive information from all managed hosts within the JumpServer environment. This creates a comprehensive data breach scenario where attackers can exfiltrate credentials, system configurations, audit logs, and other sensitive operational data. The database access capability combined with root-level container execution privileges allows for complete system compromise and potential lateral movement throughout the enterprise network. Attackers could manipulate database records, alter audit trails, and gain persistent access to critical infrastructure components that JumpServer is specifically designed to protect. The vulnerability essentially undermines the fundamental security posture of the entire JumpServer system by providing a direct attack vector that bypasses the system's own access control mechanisms.
Security mitigations for this vulnerability require immediate implementation of JumpServer version 3.10.7, which contains the necessary patches to address the input validation flaws in the Ansible integration component. Organizations should also implement additional defensive measures including network segmentation to isolate the Celery container from unnecessary network access, implementing strict input validation at multiple layers of the application architecture, and conducting comprehensive security audits of all integration components. The fix addresses the root cause by strengthening input validation mechanisms and ensuring proper sanitization of user-supplied parameters before they are processed by the Ansible execution engine. This vulnerability aligns with CWE-20, which describes improper input validation, and represents a typical example of privilege escalation through insecure input handling. From an ATT&CK perspective, this vulnerability maps to techniques involving command and script injection, privilege escalation, and credential access, making it a critical concern for organizations relying on JumpServer for their security infrastructure. Organizations should also consider implementing runtime application self-protection mechanisms and continuous monitoring to detect potential exploitation attempts.
