CVE-2024-43028: Jeecg Boot Command Injection Vulnerability

CVE-2024-43028 Overview

CVE-2024-43028 is a critical command injection vulnerability affecting the /jmreport/show component in JeecgBoot, a popular low-code development platform. This vulnerability allows remote attackers to execute arbitrary code on affected systems by sending specially crafted HTTP requests to the vulnerable endpoint. The flaw impacts JeecgBoot versions 3.0.0 through 3.5.3, potentially exposing organizations using this platform to complete system compromise.

Critical Impact

Remote attackers can achieve arbitrary code execution without authentication, potentially leading to full server compromise, data exfiltration, and lateral movement within affected networks.

Affected Products

• JeecgBoot v3.0.0
• JeecgBoot v3.1.x through v3.4.x
• JeecgBoot v3.5.0 through v3.5.3

Technical Details for CVE-2024-43028

Vulnerability Analysis

This command injection vulnerability (CWE-77) exists within the /jmreport/show endpoint of JeecgBoot's reporting module. The vulnerability stems from improper validation and sanitization of user-supplied input before it is passed to system command execution functions. When a malicious HTTP request containing command injection payloads is sent to this endpoint, the server processes the input without adequate filtering, allowing attackers to inject and execute arbitrary operating system commands.

The attack can be conducted remotely over the network and requires no authentication or user interaction, making it particularly dangerous for internet-facing JeecgBoot deployments. Successful exploitation grants attackers the ability to execute commands with the same privileges as the JeecgBoot application server process, typically resulting in significant confidentiality, integrity, and availability impacts.

Root Cause

The root cause of CVE-2024-43028 lies in insufficient input validation within the /jmreport/show component. The application fails to properly sanitize user-controlled parameters before incorporating them into system command execution contexts. This classic command injection pattern allows attackers to break out of the intended command structure and append malicious commands using shell metacharacters such as semicolons, pipes, or command substitution syntax.

Attack Vector

The attack vector is network-based, targeting the /jmreport/show HTTP endpoint. Attackers craft malicious HTTP requests containing command injection payloads within request parameters. The vulnerability requires no authentication, meaning any attacker with network access to the vulnerable endpoint can exploit this flaw.

The exploitation process involves:

1. Identifying a JeecgBoot instance running a vulnerable version (v3.0.0 - v3.5.3)
2. Sending a crafted HTTP request to the /jmreport/show endpoint with command injection payloads
3. The server processes the malicious input and executes the injected commands
4. Attackers gain code execution capabilities on the target system

Detection Methods for CVE-2024-43028

Indicators of Compromise

• Unusual HTTP requests to /jmreport/show containing shell metacharacters (;, |, $(), backticks)
• Web server logs showing requests with encoded command strings targeting the jmreport module
• Unexpected child processes spawned by the JeecgBoot application server process
• Anomalous outbound network connections from the application server to unknown external hosts

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block requests containing command injection patterns targeting /jmreport/show
• Implement log monitoring for HTTP requests to the /jmreport/ endpoint with suspicious parameter values
• Configure intrusion detection systems (IDS) to alert on common command injection payloads in HTTP traffic
• Monitor process execution chains for anomalous commands spawned by Java/application server processes

Monitoring Recommendations

• Enable verbose logging for the JeecgBoot application, particularly for the jmreport module
• Implement real-time alerting on requests to /jmreport/show containing special characters or encoded payloads
• Monitor system command execution and process creation on servers hosting JeecgBoot instances
• Review network egress traffic from application servers for suspicious data exfiltration patterns

How to Mitigate CVE-2024-43028

Immediate Actions Required

• Upgrade JeecgBoot to a patched version beyond v3.5.3 as soon as vendor releases a security update
• Restrict network access to the /jmreport/show endpoint using firewall rules or reverse proxy configurations
• Deploy WAF rules to block requests containing command injection payloads to affected endpoints
• Implement network segmentation to limit the blast radius if exploitation occurs

Patch Information

Organizations should monitor the official JeecgBoot project for security patches addressing this vulnerability. Until an official patch is available, implement the workarounds listed below to reduce exposure. Check the GitHub PoC Gist for additional technical details that may assist in developing compensating controls.

Workarounds

• Disable or restrict access to the /jmreport/show endpoint if the functionality is not required
• Implement input validation at the reverse proxy or WAF level to filter malicious characters
• Run the JeecgBoot application with minimal privileges to limit the impact of successful exploitation
• Consider temporarily taking affected JeecgBoot instances offline if they are internet-facing and cannot be protected

# Example nginx configuration to restrict access to vulnerable endpoint
location /jmreport/show {
    # Restrict to internal networks only
    allow 10.0.0.0/8;
    allow 172.16.0.0/12;
    allow 192.168.0.0/16;
    deny all;
    
    # Alternatively, return 403 to completely block
    # return 403;
