CVE-2021-27255 – NETGEAR R7800 funjsq_httpd Missing Authentication for Critical Function Remote Code Execution Vulnerability

https://notcve.org/view.php?id=CVE-2021-27255

This vulnerability allows remote attackers to execute arbitrary code on affected installations of NETGEAR R7800 firmware version 1.0.2.76. Authentication is not required to exploit this vulnerability. The specific flaw exists within the refresh_status.aspx endpoint. The issue results from a lack of authentication required to start a service on the server. An attacker can leverage this vulnerability to execute code in the context of root. • https://kb.netgear.com/000062883/Security-Advisory-for-Multiple-Vulnerabilities-on-Some-Routers-Satellites-and-Extenders https://www.zerodayinitiative.com/advisories/ZDI-21-263 • CWE-306: Missing Authentication for Critical Function •

CVE-2021-27256 – NETGEAR R7800 apply_save.cgi rc_service Command Injection Remote Code Execution Vulnerability

https://notcve.org/view.php?id=CVE-2021-27256

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R7800 firmware version 1.0.2.76. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the handling of the rc_service parameter provided to apply_save.cgi. 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/000062883/Security-Advisory-for-Multiple-Vulnerabilities-on-Some-Routers-Satellites-and-Extenders https://www.zerodayinitiative.com/advisories/ZDI-21-262 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
