CVE-2024-55546
📋 TL;DR
Missing input validation in the ORing IAP-420 web interface allows attackers to inject malicious scripts that persist in the system (stored XSS). This affects IAP-420 version 2.01e and below, potentially compromising users who access the web interface.
💻 Affected Systems
- ORing IAP-420
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attacker steals administrator credentials, takes full control of the device, and uses it as a foothold to attack other network systems.
Likely Case
Attacker steals session cookies or credentials from authenticated users, leading to unauthorized access to the device configuration.
If Mitigated
If proper network segmentation and access controls are in place, impact is limited to the device itself with no lateral movement.
🎯 Exploit Status
Exploitation requires authentication to the web interface. Public proof-of-concept exists in the referenced disclosures.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version after 2.01e (check vendor for specific fixed version)
Vendor Advisory: Not provided in references
Restart Required: Yes
Instructions:
1. Download latest firmware from ORing support portal. 2. Backup current configuration. 3. Upload firmware via web interface. 4. Reboot device. 5. Restore configuration if needed.
🔧 Temporary Workarounds
Disable web interface
allDisable the vulnerable web interface if not required for operations
Use CLI: configure terminal
no web-server enable
Restrict web interface access
linuxLimit access to web interface using firewall rules to trusted IPs only
iptables -A INPUT -p tcp --dport 80 -s trusted_ip -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -s trusted_ip -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate IAP-420 from critical systems
- Deploy web application firewall (WAF) with XSS protection rules in front of the device
🔍 How to Verify
Check if Vulnerable:
Check firmware version via web interface: System > System Information > Firmware VersionCheck Version:
curl -k https://device-ip/system_info | grep FirmwareVerify Fix Applied:
Verify firmware version is above 2.01e and test XSS payload injection in input fields📡 Detection & Monitoring
Log Indicators:
- Unusual long strings in web interface input fields
- Multiple failed login attempts followed by successful login
Network Indicators:
- Unusual outbound connections from IAP-420 device
- HTTP requests with suspicious script tags in parameters
