Description The issue is related to a buffer overflow in the wiz pptp.cgi script of Netgear router firmware, specifically when handling the pptp user ip parameter. This can be exploited by sending a specially crafted POST request, allowing a remote attacker to cause a Denial of Service (DoS).

For Netgear XR300 version 1.0.3.78, update the firmware to a version that fixes the buffer overflow issue in the wiz pptp.cgi script.
