CVE-2024-2413
📋 TL;DR
CVE-2024-2413 is a critical authentication bypass vulnerability in Intumit SmartRobot that allows remote attackers to generate valid authentication codes using a fixed encryption key. Attackers can gain administrator privileges and execute arbitrary code on affected servers. All organizations using vulnerable versions of Intumit SmartRobot are affected.
💻 Affected Systems
- Intumit SmartRobot
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attackers gaining administrator access, executing arbitrary code, and potentially establishing persistent access to the entire server environment.
Likely Case
Unauthorized administrative access leading to data theft, system manipulation, and potential lateral movement within the network.
If Mitigated
Limited impact if proper network segmentation and access controls prevent external access to vulnerable systems.
🎯 Exploit Status
Exploitation requires only knowledge of the fixed encryption key and ability to craft authentication tokens.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched version
Vendor Advisory: https://www.twcert.org.tw/tw/cp-132-7697-ecf10-1.html
Restart Required: Yes
Instructions:
1. Contact Intumit for the latest patched version
2. Apply the security update following vendor instructions
3. Restart the SmartRobot service
4. Verify authentication mechanisms are functioning correctly
🔧 Temporary Workarounds
Network Isolation
allRestrict network access to SmartRobot instances to only trusted IP addresses
Use firewall rules to block external access to SmartRobot ports
Authentication Proxy
allImplement an authentication proxy that validates requests before forwarding to SmartRobot
🧯 If You Can't Patch
- Immediately isolate affected systems from internet access
- Implement strict network segmentation and monitor all access to SmartRobot instances
🔍 How to Verify
Check if Vulnerable:
Check if authentication uses fixed encryption key by reviewing configuration or testing authentication token generationCheck Version:
Check SmartRobot version through administrative interface or configuration filesVerify Fix Applied:
Verify that authentication tokens can no longer be generated using the previously known fixed key📡 Detection & Monitoring
Log Indicators:
- Unusual authentication attempts
- Administrative actions from unexpected IP addresses
- Failed authentication followed by successful authentication with crafted tokens
Network Indicators:
- Authentication requests with crafted tokens
- Unusual administrative API calls from external sources
