CVE-2025-24470
📋 TL;DR
CVE-2025-24470 is an Improper Resolution of Path Equivalence vulnerability in FortiPortal that allows remote unauthenticated attackers to retrieve source code via crafted HTTP requests. This affects FortiPortal versions 7.4.0 through 7.4.2, 7.2.0 through 7.2.6, and 7.0.0 through 7.0.11. Attackers can potentially access sensitive information including configuration details, credentials, or proprietary code.

⚠️ Risk & Real-World Impact
Worst Case
Attackers retrieve source code containing hardcoded credentials, API keys, or sensitive configuration data, leading to full system compromise or lateral movement within the network.
Likely Case
Attackers obtain source code revealing application logic, potentially enabling further attacks or intellectual property theft.
If Mitigated
Source code exposure limited to non-sensitive files with no credentials or critical configuration data.
🎯 Exploit Status
Crafted HTTP requests can trigger the vulnerability without authentication; exploitation requires understanding of path traversal techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Update to FortiPortal 7.4.3, 7.2.7, or 7.0.12
Vendor Advisory: https://fortiguard.fortinet.com/psirt/FG-IR-25-015
Restart Required: Yes
Instructions:
1. Backup current configuration. 2. Download appropriate patch version from Fortinet support portal. 3. Apply update following FortiPortal upgrade documentation. 4. Restart FortiPortal services. 5. Verify version update.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict access to FortiPortal management interface to trusted IP addresses only
Configure firewall rules to allow only specific source IPs to FortiPortal ports (typically 443/TCP)
Web Application Firewall
allDeploy WAF with path traversal protection rules
Enable OWASP CRS rules for path traversal attacks (rule IDs 930100-930130)
🧯 If You Can't Patch
- Implement strict network segmentation to isolate FortiPortal from untrusted networks
- Deploy intrusion detection systems to monitor for path traversal attempts and source code access patterns
🔍 How to Verify
Check if Vulnerable:
Check FortiPortal version via web interface (System > Dashboard) or CLI 'get system status' commandCheck Version:
ssh admin@fortiportal get system status | grep VersionVerify Fix Applied:
Confirm version is 7.4.3, 7.2.7, 7.0.12 or later; test with controlled path traversal attempts📡 Detection & Monitoring
Log Indicators:
- HTTP requests with unusual path sequences, multiple ../ patterns, attempts to access source file extensions (.php, .py, .java)
Network Indicators:
- Unusual HTTP GET requests to FortiPortal with path traversal patterns, responses containing source code
SIEM Query:
source="fortiportal" AND (url="*../*" OR url="*..\\*" OR response_content="<?php" OR response_content="import java")
