Severity ?

8.1 (High) - CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H

CWE

CWE-121 - Stack-based Buffer Overflow

Summary

This vulnerability allows remote attackers to execute arbitrary code on affected installations of NETGEAR R6400, R6700, R7000, R7850, R7900, R8000, RS400, and XR300 routers with firmware 1.0.4.84_10.0.58. Authentication is not required to exploit this vulnerability. The specific flaw exists within the check_ra service. A crafted raePolicyVersion in a RAE_Policy.json 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 root. Was ZDI-CAN-9852.
