CVSS: 8.8EPSS: 0%CPEs: 38EXPL: 0CVE-2020-27866 – NETGEAR Multiple Routers mini_httpd Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-27866
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR R6020, R6080, R6120, R6220, R6260, R6700v2, R6800, R6900v2, R7450, JNR3210, WNR2020, Nighthawk AC2100, and Nighthawk AC2400 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the mini_httpd service, which listens on TCP port 80 by default. The issue results from incorrect string matching logic when accessing protected pages. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. • https://kb.netgear.com/000062641/Security-Advisory-for-Password-Recovery-Vulnerabilities-on-Some-Routers https://www.zerodayinitiative.com/advisories/ZDI-20-1451 • CWE-287: Improper Authentication CWE-288: Authentication Bypass Using an Alternate Path or Channel •

CVSS: 6.3EPSS: 0%CPEs: 2EXPL: 0CVE-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 •

https://notcve.org/view.php?id=CVE-2020-15636
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. • https://kb.netgear.com/000062128/Security-Advisory-for-Pre-Authentication-Stack-Overflow-on-R6700v3-PSV-2020-0224 https://www.zerodayinitiative.com/advisories/ZDI-20-937 • CWE-121: Stack-based Buffer Overflow •
