CVE-2024-36268: Apache InLong RCE Vulnerability

CVE-2024-36268 Overview

CVE-2024-36268 is a Code Injection vulnerability affecting Apache InLong, a one-stop data integration platform designed for massive data scenarios. The vulnerability exists in versions 1.10.0 through 1.12.0 and allows attackers to inject and execute arbitrary code remotely without authentication. This flaw enables complete system compromise through network-based attacks requiring no user interaction.

Critical Impact

This vulnerability enables unauthenticated remote code execution, potentially allowing attackers to gain full control over affected Apache InLong deployments and underlying infrastructure.

Affected Products

• Apache InLong 1.10.0
• Apache InLong 1.11.0
• Apache InLong 1.12.0

Technical Details for CVE-2024-36268

Vulnerability Analysis

The vulnerability stems from improper control of code generation within Apache InLong's processing logic. This Code Injection flaw (CWE-94) allows attackers to manipulate input that is subsequently used in code generation or evaluation contexts without proper sanitization. When exploited, malicious code supplied by an attacker is executed within the context of the Apache InLong application, inheriting all privileges of the running process.

The attack can be executed remotely over the network without requiring any authentication credentials or user interaction. Successful exploitation results in complete compromise of confidentiality, integrity, and availability of the affected system. Attackers can execute arbitrary commands, access sensitive data, modify configurations, and pivot to other systems within the network.

Root Cause

The root cause of CVE-2024-36268 is insufficient input validation and sanitization in code generation pathways within Apache InLong. User-controlled input is processed and incorporated into dynamically generated or evaluated code without proper filtering or escaping. This allows specially crafted input to break out of the intended context and inject arbitrary executable code.

Attack Vector

The vulnerability is exploitable over the network without authentication. An attacker can submit malicious payloads through Apache InLong's network-accessible interfaces. The attack requires low complexity and no privileges, making it highly accessible to threat actors. Once the malicious input reaches the vulnerable code generation component, the injected code executes with the permissions of the Apache InLong service account.

The attack flow involves:

1. Identifying an exposed Apache InLong instance running vulnerable versions (1.10.0 - 1.12.0)
2. Crafting a malicious payload that exploits the code injection flaw
3. Submitting the payload through network-accessible endpoints
4. Achieving arbitrary code execution on the target system

Detection Methods for CVE-2024-36268

Indicators of Compromise

• Unexpected outbound network connections from Apache InLong processes to unknown destinations
• Unusual child processes spawned by the Apache InLong service (e.g., shell processes, scripting interpreters)
• Anomalous entries in Apache InLong application logs indicating malformed or suspicious input patterns
• Unauthorized file system modifications or new files in Apache InLong directories

Detection Strategies

• Monitor Apache InLong service processes for unexpected child process creation or command execution
• Implement network traffic analysis to detect unusual patterns or connections from InLong instances
• Review application logs for error messages or stack traces that may indicate exploitation attempts
• Deploy web application firewalls (WAF) with rules to detect code injection payloads targeting InLong endpoints

Monitoring Recommendations

• Enable verbose logging on Apache InLong instances and forward logs to a centralized SIEM for analysis
• Configure alerts for process execution anomalies on systems running Apache InLong
• Implement file integrity monitoring on Apache InLong installation directories
• Monitor network segmentation boundaries for unexpected traffic from InLong systems

How to Mitigate CVE-2024-36268

Immediate Actions Required

• Upgrade all Apache InLong installations to version 1.13.0 or later immediately
• If immediate upgrade is not possible, apply the cherry-pick fix from GitHub Pull Request #10251
• Restrict network access to Apache InLong instances using firewall rules and network segmentation
• Review audit logs for any signs of exploitation prior to patching

Patch Information

Apache has addressed this vulnerability in Apache InLong version 1.13.0. Users running versions 1.10.0 through 1.12.0 should upgrade immediately. The fix is also available as a cherry-pick commit for organizations that cannot perform a full version upgrade. Detailed patch information is available in the Apache Mailing List Thread and the OpenWall OSS-Security Update.

Workarounds

• Implement strict network access controls to limit exposure of Apache InLong services to trusted networks only
• Deploy a reverse proxy or web application firewall in front of Apache InLong with input validation rules
• Disable or restrict access to vulnerable functionality if the service can operate in a limited capacity
• Monitor for exploitation attempts while planning the upgrade to version 1.13.0

# Example: Restrict Apache InLong access using iptables
# Allow only trusted internal network (adjust CIDR as needed)
iptables -A INPUT -p tcp --dport 8083 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 8083 -j DROP
