CVE-2015-6024

9.8 CRITICAL

📋 TL;DR

This vulnerability allows remote authenticated users to execute arbitrary commands on NetCommWireless HSPA 3G10WVE wireless routers by injecting shell metacharacters into the DIA_IPADDRESS parameter of ping.cgi. Attackers with valid credentials can achieve remote code execution with root privileges. Organizations using affected router firmware versions are at risk.

💻 Affected Systems

Products:
  • NetCommWireless HSPA 3G10WVE wireless router
Versions: Firmware versions before 3G10WVE-L101-S306ETS-C01_R05
Operating Systems: Embedded Linux
Default Config Vulnerable: ⚠️ Yes
Notes: Requires authenticated access, but many deployments use default credentials. The ping.cgi CGI script is typically accessible via web interface.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of the router allowing attackers to intercept all network traffic, install persistent backdoors, pivot to internal networks, and use the device for further attacks.

🟠

Likely Case

Attackers with stolen or default credentials gain full control of the router, enabling traffic monitoring, DNS hijacking, and credential theft from connected devices.

🟢

If Mitigated

With strong authentication and network segmentation, impact is limited to the router itself without lateral movement to other systems.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: CONFIRMED
Unauthenticated Exploit: ✅ No
Complexity: LOW

Multiple public exploit scripts exist. Attack requires authentication but default credentials are commonly used. Shell metacharacter injection is straightforward.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 3G10WVE-L101-S306ETS-C01_R05 or later

Vendor Advisory: Not publicly available

Restart Required: Yes

Instructions:

1. Download latest firmware from NetCommWireless support site. 2. Log into router admin interface. 3. Navigate to firmware update section. 4. Upload and apply new firmware. 5. Reboot router.

🔧 Temporary Workarounds

Disable remote administration

all

Prevent external access to router web interface

Navigate to router admin interface > Security > Remote Management > Disable

Change default credentials

all

Use strong, unique passwords for router admin access

Navigate to router admin interface > Administration > Change Password

🧯 If You Can't Patch

  • Isolate router on separate VLAN with strict firewall rules limiting inbound/outbound connections
  • Implement network monitoring for unusual traffic patterns or command execution attempts

🔍 How to Verify

Check if Vulnerable:

Check firmware version in router admin interface under System Status or About page

Check Version:

curl -s http://router-ip/cgi-bin/version.cgi or check web interface

Verify Fix Applied:

Confirm firmware version is 3G10WVE-L101-S306ETS-C01_R05 or later

📡 Detection & Monitoring

Log Indicators:

  • Unusual CGI script access patterns
  • ping.cgi requests with special characters in parameters
  • Multiple failed login attempts followed by successful login

Network Indicators:

  • Unusual outbound connections from router
  • DNS queries to suspicious domains from router
  • Unexpected SSH/Telnet connections to router

SIEM Query:

source="router_logs" AND (uri="*ping.cgi*" AND (param="*;*" OR param="*|*" OR param="*`*"))
