Descripción
*** Pendiente de traducción *** GV-I/O Box 4E is a smart embedded device with 4 input and 4 relays output that can be controlled over Ethernet and RS-485.<br />
<br />
DVRSearch is a service running by default on the IOBox listening for UDP messages on port 10001. Any user on the network can send messages to this service and interact with it. <br />
<br />
<br />
<br />
Upon receiving a UDP message, the server reads at most 1460 bytes into a local buffer and a pointer to the buffer is stored in a global variable:<br />
<br />
<br />
#### IP field stack overflow<br />
<br />
The following code is vulnerable to a stack overflow that is attacker-controlled:<br />
<br />
<br />
<br />
v3 = strlen(g_network_config->ip_addr);<br />
<br />
memcpy(&reply_buf[36], g_network_config->ip_addr, v3);
