CVE-2026-2152
📋 TL;DR
This CVE describes a remote command injection vulnerability in D-Link DIR-615 routers through the web configuration interface. Attackers can execute arbitrary operating system commands by manipulating routing parameters in the adv_routing.php file. Only unsupported D-Link DIR-615 products are affected.
💻 Affected Systems
- D-Link DIR-615
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full router compromise allowing attacker to install persistent backdoors, intercept network traffic, pivot to internal networks, or use router as botnet node.
Likely Case
Router takeover enabling network traffic monitoring, DNS hijacking, credential theft, and lateral movement to connected devices.
If Mitigated
Limited impact if router is behind firewall with restricted web interface access and network segmentation in place.
🎯 Exploit Status
Exploit details are publicly available. Attack requires web interface access but not authentication to the vulnerable component.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: N/A
Vendor Advisory: https://www.dlink.com/
Restart Required: No
Instructions:
No official patch available as product is end-of-life. Replace affected hardware with supported models.
🔧 Temporary Workarounds
Disable Web Interface
allDisable remote web configuration interface access
Access router admin panel > Administration > Remote Management > Disable
Network Segmentation
allIsolate router on separate VLAN with restricted access
🧯 If You Can't Patch
- Replace affected DIR-615 routers with supported models
- Implement strict firewall rules blocking all external access to router web interface (ports 80/443)
🔍 How to Verify
Check if Vulnerable:
Check router model and firmware version via admin interface or by accessing http://router-ip/
Check Version:
curl -s http://router-ip/ | grep -i 'dir-615' || telnet router-ip 80
Verify Fix Applied:
Verify router has been replaced or web interface is inaccessible from untrusted networks
📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to adv_routing.php
- Suspicious command execution in router logs
- Multiple failed routing configuration attempts
Network Indicators:
- Unexpected outbound connections from router
- DNS queries to malicious domains from router
- Port scans originating from router
SIEM Query:
source="router.log" AND ("adv_routing.php" OR "dest_ip" OR "submask" OR "gw") AND status=200
