CVE-2024-24780
📋 TL;DR
This vulnerability allows attackers with UDF creation privileges in Apache IoTDB to execute arbitrary code by registering malicious functions from untrusted URIs. It affects all Apache IoTDB installations from version 1.0.0 through 1.3.3. Attackers can achieve remote code execution with the privileges of the IoTDB process.
💻 Affected Systems
- Apache IoTDB
📦 What is this software?
Iotdb by Apache
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands with IoTDB process privileges, potentially leading to data theft, system destruction, or lateral movement.
Likely Case
Attackers with UDF creation access can execute arbitrary code to compromise the IoTDB server, potentially accessing sensitive time-series data or using the server as a foothold for further attacks.
If Mitigated
With proper access controls limiting UDF creation to trusted administrators only, the attack surface is significantly reduced, though the vulnerability still exists in the codebase.
🎯 Exploit Status
Exploitation requires UDF creation privileges but is straightforward once those privileges are obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.3.4
Vendor Advisory: https://lists.apache.org/thread/xphtm98v3zsk9vlpfh481m1ry2ctxvmj
Restart Required: Yes
Instructions:
1. Download Apache IoTDB 1.3.4 from official sources. 2. Stop the IoTDB service. 3. Backup configuration and data. 4. Replace the installation with version 1.3.4. 5. Restart the IoTDB service.
🔧 Temporary Workarounds
Restrict UDF Creation Privileges
allLimit UDF creation to only trusted administrators by modifying user permissions.
# Review and modify user permissions in IoTDB configuration
# Revoke CREATE_FUNCTION privilege from untrusted users
Network Segmentation
linuxIsolate IoTDB instances from untrusted networks and limit access to trusted IPs only.
# Configure firewall rules to restrict access
# Example: iptables -A INPUT -p tcp --dport 6667 -s trusted_ip -j ACCEPT
🧯 If You Can't Patch
- Immediately restrict UDF creation privileges to only essential, trusted administrators
- Implement network controls to limit IoTDB access to trusted sources only
🔍 How to Verify
Check if Vulnerable:
Check the IoTDB version using the version command or configuration files. Versions 1.0.0 through 1.3.3 are vulnerable.Check Version:
./sbin/start-cli.sh -h localhost -p 6667 -u root -pw root -e "show version"Verify Fix Applied:
Confirm the installed version is 1.3.4 or later by checking the version output.📡 Detection & Monitoring
Log Indicators:
- Unusual UDF registration attempts
- UDF registrations from unexpected sources
- Error logs related to UDF loading failures
Network Indicators:
- Unexpected connections to IoTDB port (default 6667)
- Suspicious network traffic patterns to/from IoTDB instances
