CVE-2024-10698
📋 TL;DR
This critical vulnerability in Tenda AC6 routers allows remote attackers to execute arbitrary code via a stack-based buffer overflow in the device name setting function. Attackers can exploit this without authentication to potentially take full control of affected routers. Users with Tenda AC6 routers running firmware version 15.03.05.19 are affected.
💻 Affected Systems
- Tenda AC6
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete router compromise, allowing attackers to intercept traffic, deploy malware, pivot to internal networks, or create persistent backdoors.
Likely Case
Router takeover enabling traffic interception, DNS hijacking, credential theft, and network reconnaissance.
If Mitigated
Limited impact if routers are behind firewalls with strict inbound filtering, though internal threats remain possible.
🎯 Exploit Status
Public exploit code exists on GitHub, making exploitation straightforward for attackers with basic skills.
