CVE-2022-27642 – NETGEAR R6700v3 httpd Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2022-27642
This vulnerability allows network-adjacent attackers to bypass authentication 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 httpd service. 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/000064723/Security-Advisory-for-Multiple-Vulnerabilities-on-Multiple-Products-PSV-2021-0327 https://www.zerodayinitiative.com/advisories/ZDI-22-518 • CWE-863: Incorrect Authorization •
CVE-2022-27647 – NETGEAR R6700v3 libreadycloud.so Command Injection Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2022-27647
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6700v3 1.0.4.120_10.0.91 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the handling of the name or email field provided to libreadycloud.so. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. • https://kb.netgear.com/000064723/Security-Advisory-for-Multiple-Vulnerabilities-on-Multiple-Products-PSV-2021-0327 https://www.zerodayinitiative.com/advisories/ZDI-22-524 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2022-27645 – NETGEAR R6700v3 readycloud_control.cgi Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2022-27645
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR R6700v3 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within readycloud_control.cgi. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to execute code in the context of root. • https://kb.netgear.com/000064722/Security-Advisory-for-Sensitive-Information-Disclosure-on-Some-Routers-and-Fixed-Wireless-Products-PSV-2021-0325 https://www.zerodayinitiative.com/advisories/ZDI-22-522 • CWE-306: Missing Authentication for Critical Function CWE-697: Incorrect Comparison •
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 •
