CVE-2022-27641 (GCVE-0-2022-27641)

Vulnerability from cvelistv5 – Published: 2023-03-29 00:00 – Updated: 2025-02-18 17:50

Summary

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6700v3 1.0.4.120_10.0.91 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the NetUSB module. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-15806.
