Description
A buffer overflow in the Mercury MR816v2 (081C3114 4.8.7 Build 110427 Rel 36550n) occurs when the device accepts and stores excessively long hostnames from LAN hosts without proper length validation. The affected code performs unchecked copies/concatenations into fixed-size buffers. A crafted long hostname can overflow the buffer, cause a crash (DoS) and potentially enabling remote code execution.

Executive Summary

This vulnerability is a buffer overflow in the Mercury MR816v2 device that occurs when the device accepts and stores excessively long hostnames from LAN hosts without properly checking their length. The device's code copies or concatenates these hostnames into fixed-size buffers without validation, which can cause the buffer to overflow. This overflow can lead to a crash (denial of service) and potentially allow an attacker to execute code remotely.

Impact Analysis

The vulnerability can impact you by causing the affected device to crash, resulting in denial of service. More seriously, it may allow an attacker to execute arbitrary code remotely on the device, potentially compromising the device and the network it is connected to.
