CVE-2021-34947 – NETGEAR R7800 net-cgi Out-Of-Bounds Write Remote Code Execution Vulnerability

https://notcve.org/view.php?id=CVE-2021-34947

NETGEAR R7800 net-cgi Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R7800 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of the soap_block_table file. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of root. . • https://kb.netgear.com/000064044/Security-Advisory-for-Pre-Authentication-Buffer-Overflow-on-Some-Routers-PSV-2021-0129 https://www.zerodayinitiative.com/advisories/ZDI-21-1116 • CWE-787: Out-of-bounds Write •
