CVE-2021-34991 – NETGEAR R6400v2 UPnP uuid Stack-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-34991
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6400v2 1.0.4.106_10.0.80 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the UPnP service, which listens on TCP port 5000 by default. When parsing the uuid request header, the process does not properly validate 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 root. • https://kb.netgear.com/000064361/Security-Advisory-for-Pre-Authentication-Buffer-Overflow-on-Multiple-Products-PSV-2021-0168 https://www.zerodayinitiative.com/advisories/ZDI-21-1303 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2021-34977 – NETGEAR R7000 SOAP ParentalControl Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2021-34977
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR R7000 1.0.11.116_10.2.100 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of SOAP requests. The issue results from the lack of proper authentication verification before performing a password reset. An attacker can leverage this vulnerability to reset the admin password. • https://kb.netgear.com/000064046/Security-Advisory-for-Authentication-Bypass-on-Some-Routers-and-DSL-Modem-Routers-PSV-2021-0134 https://www.zerodayinitiative.com/advisories/ZDI-21-1239 • CWE-287: Improper Authentication CWE-288: Authentication Bypass Using an Alternate Path or Channel •
