NETGEAR R6700 Stack-based buffer overflow vulnerability in routers

Trust: 0.8

sources: JVNDB: JVNDB-2020-008850

DESCRIPTION

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6700 V1.0.4.84_10.0.58 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of string table file uploads. A crafted gui_region in a string table file can trigger an overflow of a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the web server. Was ZDI-CAN-9756. Zero Day Initiative To this vulnerability ZDI-CAN-9756 Was numbered.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. NETGEAR R6700 is a wireless router made by NETGEAR. The vulnerability stems from the failure of the program to correctly verify the data length before copying the user-supplied data to the stack-based fixed buffer
