CVE-2022-27641 – Netgear R6700v3 NetUSB Integer Overflow Remote Code Execution Vulnerability

https://notcve.org/view.php?id=CVE-2022-27641

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. • https://kb.netgear.com/000064437/Security-Advisory-for-Pre-Authentication-Buffer-Overflow-on-Multiple-Products-PSV-2021-0278 https://www.zerodayinitiative.com/advisories/ZDI-22-544 • CWE-190: Integer Overflow or Wraparound •
