CVE-2024-54027
📋 TL;DR
This vulnerability allows a privileged attacker with super-admin profile and CLI access to read sensitive data via hard-coded cryptographic keys in FortiSandbox. It affects multiple versions of FortiSandbox across different release branches. The attacker must already have administrative CLI access to exploit this vulnerability.

⚠️ Risk & Real-World Impact
Worst Case
A malicious insider or compromised administrator could decrypt sensitive data stored or transmitted by FortiSandbox, potentially exposing confidential information, credentials, or security configurations.
Likely Case
An attacker with legitimate administrative access could abuse their privileges to access sensitive data they shouldn't normally be able to view, violating the principle of least privilege.
If Mitigated
With proper access controls and monitoring, the impact is limited to authorized administrators who follow security policies and procedures.
🎯 Exploit Status
Exploitation requires existing administrative CLI access. No public exploit code is known at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Fortinet advisory for specific patched versions
Vendor Advisory: https://fortiguard.fortinet.com/psirt/FG-IR-24-327
Restart Required: No
Instructions:
1. Review Fortinet advisory FG-IR-24-327. 2. Upgrade to patched versions as specified by Fortinet. 3. Verify the update was successful.
🔧 Temporary Workarounds
Restrict CLI Access
allLimit CLI access to only necessary administrators and implement strict access controls
Implement Monitoring
allMonitor CLI access logs for unusual activity or unauthorized access attempts
🧯 If You Can't Patch
- Implement strict role-based access control (RBAC) to limit who has super-admin privileges
- Enable detailed logging and monitoring of all CLI access and review logs regularly
🔍 How to Verify
Check if Vulnerable:
Check FortiSandbox version via CLI: 'get system status' and compare against affected versions listCheck Version:
get system statusVerify Fix Applied:
After patching, verify version is no longer in affected range and test that sensitive data access controls are functioning properly📡 Detection & Monitoring
Log Indicators:
- Unusual CLI access patterns
- Multiple failed CLI authentication attempts followed by success
- Access to sensitive data files or commands
Network Indicators:
- Unusual SSH or CLI connections to FortiSandbox management interfaces
SIEM Query:
