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') •
