CVE-2025-60697

7.3 HIGH

📋 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

Products:
  • D-Link DIR-882 Router
Versions: Firmware DIR882A1_FW102B02 and likely earlier versions
Operating Systems: Embedded Linux (router firmware)
Default Config Vulnerable: ⚠️ Yes
Notes: Vulnerability exists in default configuration through the web interface. DDNS functionality must be accessible.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete device compromise allowing attackers to install persistent malware, pivot to internal networks, intercept all network traffic, or brick the device.

🟠

Likely Case

Attackers gain shell access to execute commands, potentially installing backdoors, modifying router settings, or using the device for botnet activities.

🟢

If Mitigated

If web interface access is restricted or DDNS is disabled, attack surface is reduced but vulnerability may still be reachable through other vectors.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Public GitHub repositories contain detailed analysis and likely exploit code. Unauthenticated nature makes exploitation straightforward.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: https://www.dlink.com/en/security-bulletin/

Restart Required: Yes

Instructions:

1. Check D-Link security bulletin for firmware updates. 2. Download latest firmware from D-Link support site. 3. Log into router web interface. 4. Navigate to firmware update section. 5. Upload and install new firmware. 6. Reboot router after installation.

🔧 Temporary Workarounds

Disable DDNS Service

all

Disable Dynamic DNS functionality to prevent exploitation through vulnerable parameters

Login to router web interface -> Advanced -> DDNS Settings -> Disable DDNS

Restrict Web Interface Access

all

Limit web interface access to trusted IP addresses only

Login to router -> Advanced -> Firewall -> Access Control -> Add rules to restrict web interface access

🧯 If You Can't Patch

  • Isolate router on separate VLAN with strict firewall rules
  • Replace vulnerable device with supported hardware

🔍 How to Verify

Check if Vulnerable:

Check firmware version in router web interface under System -> Firmware. If version is DIR882A1_FW102B02 or earlier, device is likely vulnerable.

Check Version:

Login to router web interface and navigate to System -> Firmware Information

Verify Fix Applied:

Verify firmware version has been updated to a version later than DIR882A1_FW102B02. Check D-Link security advisory for specific patched versions.

📡 Detection & Monitoring

Log Indicators:

  • Unusual HTTP POST requests to prog.cgi with DDNS parameters
  • Shell command execution from web interface processes
  • Unexpected process creation from router services

Network Indicators:

  • Unusual outbound connections from router
  • HTTP requests with command injection patterns in parameters
  • Traffic to unexpected external IPs from router

SIEM Query:

source="router_logs" AND (uri="/prog.cgi" AND (param="ServerAddress" OR param="Hostname") AND value MATCHES "[;|&`$()]" )
