CVE-2025-15007
📋 TL;DR
A stack-based buffer overflow vulnerability in Tenda WH450 routers allows remote attackers to execute arbitrary code by sending specially crafted HTTP requests to the /goform/L7Im endpoint. This affects Tenda WH450 router users running firmware version 1.0.0.18. The vulnerability is remotely exploitable without authentication.
💻 Affected Systems
- Tenda WH450
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise leading to persistent backdoor installation, network traffic interception, lateral movement to connected devices, and botnet recruitment.
Likely Case
Remote code execution allowing attacker to modify router settings, intercept traffic, or use the device as a pivot point for further attacks.
If Mitigated
Limited impact if device is behind firewall with restricted inbound access, though internal threats remain possible.
🎯 Exploit Status
Public proof-of-concept available on GitHub demonstrates exploitation. Attack requires sending crafted HTTP request to vulnerable endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
Check Tenda official website for firmware updates. If update available, download and install via router web interface under System Tools > Firmware Upgrade.
🔧 Temporary Workarounds
Block External Access
allConfigure firewall to block inbound HTTP/HTTPS access to router from internet
Disable Remote Management
allTurn off remote management feature in router settings
🧯 If You Can't Patch
- Replace affected router with different model/vendor
- Segment network to isolate router from critical systems
🔍 How to Verify
Check if Vulnerable:
Check router firmware version in web interface (typically under System Status or About). If version is 1.0.0.18, device is vulnerable.Check Version:
curl -s http://router-ip/ | grep -i version or check web interfaceVerify Fix Applied:
Verify firmware version has changed from 1.0.0.18 to a newer version after update.📡 Detection & Monitoring
Log Indicators:
- HTTP requests to /goform/L7Im with unusual 'page' parameter values
- Router crash/reboot events
- Unusual outbound connections from router
Network Indicators:
- HTTP POST requests to /goform/L7Im endpoint with long parameter values
- Traffic patterns suggesting router compromise
