CVE-2024-52755
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code or cause denial of service via a buffer overflow in the host_ip parameter of the ipsec_road_asp function in D-LINK DI-8003 routers. Attackers can exploit this by sending specially crafted requests to affected devices. Organizations using vulnerable D-LINK DI-8003 routers are affected.
💻 Affected Systems

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete device compromise, network infiltration, and lateral movement within the network.
Likely Case
Denial of service causing router instability or crashes, disrupting network connectivity.
If Mitigated
Limited impact with proper network segmentation and firewall rules blocking unauthorized access to management interfaces.
🎯 Exploit Status
Public proof-of-concept exists in GitHub repository, making exploitation straightforward for attackers with basic skills.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: Yes
Instructions:
1. Check D-LINK official website for firmware updates. 2. Download latest firmware if available. 3. Upload firmware through router web interface. 4. Reboot router after update.
🔧 Temporary Workarounds
Disable IPSec Road Warrior Feature
allDisable the vulnerable ipsec_road_asp function if not required for operations.
Restrict Management Interface Access
allConfigure firewall rules to allow management access only from trusted IP addresses.
🧯 If You Can't Patch
- Segment network to isolate vulnerable routers from critical systems
- Implement strict network monitoring for unusual traffic patterns to the router management interface
🔍 How to Verify
Check if Vulnerable:
Check router firmware version through web interface: Login > System > Firmware InformationCheck Version:
