CVE-2024-32350
📋 TL;DR
This vulnerability allows authenticated attackers to execute arbitrary commands on TOTOLINK X5000R routers by exploiting improper input validation in the ipsecPsk parameter. Attackers with valid credentials can gain full system control. Only TOTOLINK X5000R routers running the affected firmware are impacted.
💻 Affected Systems
- TOTOLINK X5000R
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the router allowing attackers to intercept network traffic, pivot to internal networks, install persistent backdoors, or use the device for botnet activities.
Likely Case
Attackers with stolen or default credentials execute commands to reconfigure the router, steal credentials, or deploy malware on connected devices.
If Mitigated
Limited to authenticated users only, with proper credential management reducing attack surface.
🎯 Exploit Status
Exploit requires authentication but is straightforward once credentials are obtained.
