CVE-2025-60701
📋 TL;DR
This CVE describes a command injection vulnerability in D-Link DIR-882 router firmware that allows unauthenticated remote attackers to execute arbitrary commands on the device. Attackers can exploit this by sending specially crafted HTTP requests to the router's web interface. All users of affected D-Link DIR-882 routers with vulnerable firmware are at risk.
💻 Affected Systems
- D-Link DIR-882 Router
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the router allowing attackers to install persistent malware, intercept all network traffic, pivot to internal network devices, or use the router as part of a botnet.
Likely Case
Router compromise leading to network traffic interception, DNS hijacking, credential theft, and lateral movement to connected devices.
If Mitigated
Limited impact if router is behind firewall with restricted WAN access, though internal attackers could still exploit.
🎯 Exploit Status
Public proof-of-concept available on GitHub. Exploitation requires sending HTTP requests to router web interface.

allPrevent external access to router web interface
Restrict Web Interface Access
allLimit access to router admin interface to trusted IPs only
🧯 If You Can't Patch
- Replace affected router with different model
- Place router behind firewall with strict inbound rules blocking web interface access
🔍 How to Verify
Check if Vulnerable:
Check router firmware version in admin interface. If version is DIR882A1_FW102B02, device is vulnerable.Check Version:
Log into router web interface and check System Status or Firmware Update sectionVerify Fix Applied:
Verify firmware version has been updated to a version later than DIR882A1_FW102B02.📡 Detection & Monitoring
