CVE-2024-39340
📋 TL;DR
This vulnerability allows attackers to bypass two-factor authentication (2FA) in Securepoint UTM by exploiting improper handling of OTP keys. Attackers can gain unauthorized access to administrative interfaces and user portals without providing the second authentication factor. Organizations using affected Securepoint UTM versions with OTP enabled are vulnerable.
💻 Affected Systems
- Securepoint UTM
- Securepoint Reseller Preview
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the UTM device, allowing attackers to reconfigure firewall rules, intercept network traffic, disable security controls, and gain persistent access to the protected network.
Likely Case
Unauthorized access to administrative interfaces leading to configuration changes, privilege escalation, and potential lateral movement within the network.
If Mitigated
Limited impact if strong network segmentation, additional authentication layers, and monitoring are in place to detect unauthorized access attempts.
🎯 Exploit Status
Exploitation requires knowledge of valid username/password credentials but bypasses the OTP requirement. No public exploit code has been disclosed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: UTM 12.6.5 and 12.7.1
Vendor Advisory: https://wiki.securepoint.de/Advisory/CVE-2024-39340
Restart Required: Yes
Instructions:
1. Backup current configuration. 2. Download and install UTM 12.6.5 or 12.7.1 from Securepoint portal. 3. Apply the update through the web interface or CLI. 4. Reboot the system. 5. Verify the update was successful.
🔧 Temporary Workarounds
Disable OTP Authentication
allTemporarily disable OTP/two-factor authentication until patching can be completed
Restrict Access to Management Interfaces
allLimit access to administration and user portals to trusted IP addresses only
🧯 If You Can't Patch
- Implement network segmentation to isolate UTM management interfaces from untrusted networks
- Enable detailed logging and monitoring for authentication attempts and configuration changes
🔍 How to Verify
Check if Vulnerable:
Check UTM version in web interface under System > Status or via CLI command 'show version'. If version is between 11.5-12.6.4 or exactly 12.7.0, and OTP is enabled, the system is vulnerable.Check Version:
show versionVerify Fix Applied:
Verify version is 12.6.5 or higher (or 12.7.1 for Reseller Preview) and test OTP authentication functionality.📡 Detection & Monitoring
Log Indicators:
- Successful authentication without OTP verification when OTP is enabled
- Multiple failed OTP attempts followed by successful login
- Authentication from unusual IP addresses
Network Indicators:
- Unauthorized access to /admin or /userportal endpoints
- Traffic patterns indicating configuration changes
SIEM Query:
