CVE-2023-30771
📋 TL;DR
This CVE describes an incorrect authorization vulnerability in Apache IoTDB's web-workbench component (version 0.13.3). Attackers can bypass authorization controls to access or manipulate database resources without proper authentication. Organizations using IoTDB with the optional web-workbench component enabled are affected.
💻 Affected Systems
- Apache IoTDB iotdb-web-workbench component
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the IoTDB instance allowing unauthorized data access, modification, or deletion, potentially leading to data breach or system takeover.
Likely Case
Unauthorized access to sensitive IoT data, configuration manipulation, or privilege escalation within the database system.
If Mitigated
Limited impact if proper network segmentation and access controls prevent external access to the web-workbench interface.
🎯 Exploit Status
Authorization bypass vulnerabilities typically require minimal technical skill to exploit once details are known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: iotdb-web-workbench version 0.13.4 and later
Vendor Advisory: https://lists.apache.org/thread/08nc3dr6lshfppx0pzmz5vbggdnzpojb
Restart Required: Yes
Instructions:
1. Stop the IoTDB service. 2. Update the iotdb-web-workbench component to version 0.13.4 or later. 3. Restart the IoTDB service. 4. Verify the web-workbench is functioning correctly.
🔧 Temporary Workarounds
Disable web-workbench component
allRemove or disable the vulnerable web-workbench component if not required
Stop IoTDB service
Remove or disable web-workbench module from IoTDB installation
Network access restriction
linuxRestrict network access to the web-workbench port (default 8080)
iptables -A INPUT -p tcp --dport 8080 -j DROP
ufw deny 8080/tcp
🧯 If You Can't Patch
- Disable the web-workbench component entirely if not required for operations
- Implement strict network access controls to limit access to the web-workbench interface to trusted IPs only
🔍 How to Verify
Check if Vulnerable:
Check the version of iotdb-web-workbench component. If version is 0.13.3, the system is vulnerable.Check Version:
Check IoTDB configuration files or web-workbench interface for version informationVerify Fix Applied:
Verify iotdb-web-workbench version is 0.13.4 or later and test authorization controls are functioning properly.📡 Detection & Monitoring
Log Indicators:
