CVE-2020-15634 – NETGEAR R6700 httpd strtblupgrade Format String Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-15634
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6700 routers with firmware 1.0.4.84_10.0.58. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of string table file uploads. The issue results from the lack of proper validation of a user-supplied string before using it as a format specifier. An attacker can leverage this vulnerability to execute code in the context of the web server. • https://kb.netgear.com/000062126/Security-Advisory-for-Pre-Authentication-Command-Injection-on-R6700v3-PSV-2020-0189 https://www.zerodayinitiative.com/advisories/ZDI-20-935 • CWE-134: Use of Externally-Controlled Format String •
CVE-2020-15635 – NETGEAR R6700 acsd Stack-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-15635
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6700 V1.0.4.84_10.0.58 routers with firmware 1.0.4.84_10.0.58. Authentication is not required to exploit this vulnerability. The specific flaw exists within the acsd service, which listens on TCP port 5916 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 the admin user. • https://kb.netgear.com/000062127/Security-Advisory-for-Pre-Authentication-Buffer-Overflow-on-R6700v3-PSV-2020-0202 https://www.zerodayinitiative.com/advisories/ZDI-20-936 • CWE-121: Stack-based Buffer Overflow •
