CVE-2025-55564
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on Tenda AC15 routers via a stack overflow in the fromSetIpMacBind function. Attackers can exploit this by sending specially crafted requests to the affected device. Users running Tenda AC15 routers with the vulnerable firmware are affected.
💻 Affected Systems
- Tenda AC15
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete device compromise, network traffic interception, and lateral movement to other devices on the network.
Likely Case
Router compromise allowing attackers to modify network settings, intercept traffic, or use the device as a foothold for further attacks.
If Mitigated
Limited impact if device is behind firewall with restricted access, though internal network exposure remains a concern.
🎯 Exploit Status
Public proof-of-concept exists on GitHub, making exploitation straightforward for attackers with basic skills.
