Trust: 0.8

sources: JVNDB: JVNDB-2020-008761

DESCRIPTION

This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR R6700 V1.0.4.84_10.0.58 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the UPnP service, which listens on TCP port 5000 by default. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length, stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-9643. NETGEAR R6700 A stack-based buffer overflow vulnerability exists in the router. Zero Day Initiative To this vulnerability ZDI-CAN-9643 Was numbered.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state.
