| Título | TOTOLINK T6 V4.1.5cu.748_B20211015 Buffer Overflow |
|---|
| Descripción | The T6 routers has many shared library that will be loaded in memory when running. In function tcpcheck_net, the v7 buffer is 128 bytes, and the sprintf doesn't check for the length of input.
An attacker can send a malicious packet (both MQTT and HTTP) and overwrite the saved return address, lead it to RCE.
