CVE-2025-15179

7.2 HIGH

📋 TL;DR

A stack-based buffer overflow vulnerability in Tenda WH450 router firmware version 1.0.0.18 allows remote attackers to execute arbitrary code by manipulating the 'page' parameter in the /goform/qossetting endpoint. This affects all users running the vulnerable firmware version on their Tenda WH450 routers. Successful exploitation could lead to complete device compromise.

💻 Affected Systems

Products:
  • Tenda WH450
Versions: 1.0.0.18
Operating Systems: Embedded router firmware
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerable endpoint /goform/qossetting is part of the web management interface. No special configuration is required for exploitation.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution leading to full router compromise, credential theft, network traffic interception, and lateral movement into connected devices.

🟠

Likely Case

Router crash/reboot causing temporary network disruption, or limited code execution allowing attacker persistence on the device.

🟢

If Mitigated

Denial of service from failed exploitation attempts or limited impact if proper network segmentation isolates the router.

🌐 Internet-Facing: HIGH - The vulnerability is remotely exploitable and routers are typically internet-facing devices.
🏢 Internal Only: MEDIUM - Internal attackers could exploit this if they have network access to the router's management interface.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Public proof-of-concept exists in GitHub repositories. The vulnerability requires no authentication and has straightforward exploitation.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: Not available

Restart Required: Yes

Instructions:

1. Check Tenda official website for firmware updates. 2. Download latest firmware for WH450. 3. Access router web interface. 4. Navigate to System Tools > Firmware Upgrade. 5. Upload and install new firmware. 6. Reboot router after installation.

🔧 Temporary Workarounds

Disable remote management

all

Prevent external access to router management interface

Network segmentation

all

Isolate router management interface to trusted network segment only

🧯 If You Can't Patch

  • Replace affected router with different model or vendor
  • Implement strict firewall rules blocking all external access to router management interface (ports 80/443)

🔍 How to Verify

Check if Vulnerable:

Check router firmware version via web interface: Login > System Tools > Firmware Version. If version is 1.0.0.18, device is vulnerable.

Check Version:

curl -s http://router-ip/goform/getStatus | grep version (if API available)

Verify Fix Applied:

Verify firmware version has changed from 1.0.0.18 to a newer version after update.

📡 Detection & Monitoring

Log Indicators:

  • Multiple POST requests to /goform/qossetting with large 'page' parameter values
  • Router crash/reboot logs
  • Unusual process execution in router logs

Network Indicators:

  • Unusual traffic patterns to router management interface
  • POST requests to /goform/qossetting from external IPs
  • Buffer overflow patterns in HTTP requests

SIEM Query:

source="router_logs" AND (url="/goform/qossetting" OR message="*buffer overflow*" OR message="*segmentation fault*")
