CVE-2024-35275
📋 TL;DR
This SQL injection vulnerability in Fortinet FortiAnalyzer and FortiManager allows attackers to execute arbitrary SQL commands through specially crafted HTTP requests, potentially leading to privilege escalation. Affected systems are FortiAnalyzer and FortiManager versions 7.4.0 through 7.4.2. Attackers could gain administrative access to these management platforms.
💻 Affected Systems
- Fortinet FortiAnalyzer
- Fortinet FortiManager
📦 What is this software?
Fortianalyzer by Fortinet
Fortimanager by Fortinet
⚠️ Risk & Real-World Impact
Worst Case
Full compromise of FortiAnalyzer/FortiManager with administrative privileges, allowing attacker to modify configurations, access sensitive logs, deploy malicious firmware, and pivot to managed devices.
Likely Case
Privilege escalation to administrative access on the management platform, enabling configuration changes and data access.
If Mitigated
Limited impact if proper network segmentation and access controls prevent unauthorized HTTP requests to management interfaces.
🎯 Exploit Status
Exploitation requires sending specially crafted HTTP requests to vulnerable endpoints. Authentication status not specified in advisory.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 7.4.3 or later
Vendor Advisory: https://fortiguard.fortinet.com/psirt/FG-IR-24-091
Restart Required: Yes
Instructions:
1. Download FortiAnalyzer/FortiManager 7.4.3 or later from Fortinet support portal. 2. Backup current configuration. 3. Upload and install firmware update via web interface or CLI. 4. Reboot device after installation completes.
🔧 Temporary Workarounds
Restrict Management Interface Access
allLimit network access to FortiAnalyzer/FortiManager management interfaces to trusted IP addresses only.
config system interface
edit <mgmt_interface>
set allowaccess https ssh ping
set trust-ip-1 <trusted_ip>
end
Enable Web Application Firewall
allConfigure WAF rules to detect and block SQL injection patterns in HTTP requests.
config waf profile
edit default
config signature
set status enable
end
end
🧯 If You Can't Patch
- Implement strict network segmentation to isolate management interfaces from untrusted networks.
- Deploy web application firewall with SQL injection detection rules in front of management interfaces.
🔍 How to Verify
Check if Vulnerable:
Check system version via web interface (System > Dashboard) or CLI command: get system statusCheck Version:
get system status | grep VersionVerify Fix Applied:
Verify version is 7.4.3 or later using: get system status | grep Version📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in system logs
- Multiple failed authentication attempts followed by successful admin login
- Configuration changes from unexpected source IPs
Network Indicators:
- HTTP requests with SQL syntax in parameters to management interface
- Unusual outbound connections from management appliance
