CVE-2013-10059
📋 TL;DR
This CVE describes an authenticated OS command injection vulnerability in D-Link DIR-615H1 routers running firmware version 8.04. Attackers with default credentials can inject arbitrary shell commands via the ping_ipaddr parameter in the tools_vct.htm diagnostic interface, potentially gaining full control of affected routers. This affects users who haven't changed default credentials or applied patches.
💻 Affected Systems
- D-Link DIR-615H1
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete router compromise allowing attacker to intercept all network traffic, install persistent backdoors, pivot to internal networks, and brick the device.
Likely Case
Router takeover leading to DNS hijacking, credential theft from network traffic, and installation of malware on connected devices.
If Mitigated
Limited impact if strong authentication is enforced and network segmentation isolates the router management interface.
🎯 Exploit Status
Metasploit module available. Exploitation requires authentication but default credentials are often unchanged. Backtick encapsulation used for command injection.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown - check D-Link support for latest firmware
Vendor Advisory: https://support.dlink.com/
Restart Required: Yes
Instructions:
1. Log into router admin interface. 2. Navigate to firmware update section. 3. Download latest firmware from D-Link support site. 4. Upload and apply firmware update. 5. Reboot router.
🔧 Temporary Workarounds
Disable remote management
allPrevent external access to router web interface
Change default credentials
allUse strong, unique admin password
🧯 If You Can't Patch
- Isolate router management interface to trusted internal network only
- Implement network monitoring for unusual outbound connections from router
🔍 How to Verify
Check if Vulnerable:
Check if router model is DIR-615H1 with firmware version 8.04 via admin interfaceCheck Version:
Login to router web interface and check System Status or Firmware sectionVerify Fix Applied:
Verify firmware version is updated beyond 8.04 and test tools_vct.htm endpoint with command injection attempts📡 Detection & Monitoring
Log Indicators:
- Unusual commands in router logs
- Multiple failed login attempts followed by successful login
Network Indicators:
- Unexpected outbound connections from router
- DNS queries to suspicious domains
SIEM Query:
