| Title | Tenda O3V2 1.0.0.12(3880) Stack-based Buffer Overflow |
|---|
| Description | We found an stack overflow vulnerability in Tenda router with firmware which was released recently, allows remote attackers to crash the server.In the router's formWifiBasicSet function, extChannel is directly passed by the attacker, If this part of the data is too long, it will cause the stack overflow, so we can control the extChannel to execute arbitrary code. |
