CVE-2021-35973
https://notcve.org/view.php?id=CVE-2021-35973
NETGEAR WAC104 devices before 1.0.4.15 are affected by an authentication bypass vulnerability in /usr/sbin/mini_httpd, allowing an unauthenticated attacker to invoke any action by adding the ¤tsetting.htm substring to the HTTP query, a related issue to CVE-2020-27866. This directly allows the attacker to change the web UI password, and eventually to enable debug mode (telnetd) and gain a shell on the device as the admin limited-user account (however, escalation to root is simple because of weak permissions on the /etc/ directory). Los dispositivos NETGEAR WAC104 versiones anteriores a 1.0.4.15 están afectados por una vulnerabilidad de omisión de autenticación en /usr/sbin/mini_httpd, que permite a un atacante no autenticado invocar cualquier acción añadiendo la subcadena &currentsetting.htm a la consulta HTTP, un problema relacionado con CVE-2020-27866. Esto permite directamente al atacante cambiar la contraseña de la interfaz web, y eventualmente habilitar el modo de depuración (telnetd) y obtener un shell en el dispositivo como la cuenta de usuario limitado admin (sin embargo, la escalada a root es sencilla debido a los permisos débiles en el directorio /etc/) • https://gynvael.coldwind.pl/?lang=en&id=736 https://kb.netgear.com/000063785/Security-Advisory-for-Authentication-Bypass-on-WAC104-PSV-2021-0075 • CWE-697: Incorrect Comparison •
CVE-2021-33514
https://notcve.org/view.php?id=CVE-2021-33514
Certain NETGEAR devices are affected by command injection by an unauthenticated attacker via the vulnerable /sqfs/lib/libsal.so.0.0 library used by a CGI application, as demonstrated by setup.cgi?token=';$HTTP_USER_AGENT;' with an OS command in the User-Agent field. This affects GC108P before 1.0.7.3, GC108PP before 1.0.7.3, GS108Tv3 before 7.0.6.3, GS110TPPv1 before 7.0.6.3, GS110TPv3 before 7.0.6.3, GS110TUPv1 before 1.0.4.3, GS710TUPv1 before 1.0.4.3, GS716TP before 1.0.2.3, GS716TPP before 1.0.2.3, GS724TPPv1 before 2.0.4.3, GS724TPv2 before 2.0.4.3, GS728TPPv2 before 6.0.6.3, GS728TPv2 before 6.0.6.3, GS752TPPv1 before 6.0.6.3, GS752TPv2 before 6.0.6.3, MS510TXM before 1.0.2.3, and MS510TXUP before 1.0.2.3. Determinados dispositivos NETGEAR están afectados por una inyección de comandos por un atacante no autenticado por medio de la biblioteca vulnerable /sqfs/lib/libsal.so.0.0 usado por una aplicación CGI, como es demostrado por setup.cgi?token=';$HTTP_USER_AGENT;' con un comando del sistema operativo en el campo User-Agent. • https://gynvael.coldwind.pl/?lang=en&id=733 https://kb.netgear.com/000063641/Security-Advisory-for-Pre-Authentication-Command-Injection-Vulnerability-on-Some-Smart-Switches-PSV-2021-0071 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2021-31802 – Netgear R7000 Backup.cgi Heap Overflow Remote Code Execution
https://notcve.org/view.php?id=CVE-2021-31802
NETGEAR R7000 1.0.11.116 devices have a heap-based Buffer Overflow that is exploitable from the local network without authentication. The vulnerability exists within the handling of an HTTP request. An attacker can leverage this to execute code as root. The problem is that a user-provided length value is trusted during a backup.cgi file upload. The attacker must add a \n before the Content-Length header. • https://ssd-disclosure.com/ssd-advisory-netgear-nighthawk-r7000-httpd-preauth-rce https://www.netgear.com/about/security • CWE-787: Out-of-bounds Write •
CVE-2021-27272 – NETGEAR ProSAFE Network Management System ReportTemplateController Directory Traversal Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-27272
This vulnerability allows remote attackers to delete arbitrary files on affected installations of NETGEAR ProSAFE Network Management System 1.6.0.26. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the ReportTemplateController class. When parsing the path parameter, the process does not properly validate a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. • https://kb.netgear.com/000062723/Security-Advisory-for-Denial-of-Service-on-NMS300-PSV-2020-0537 https://www.zerodayinitiative.com/advisories/ZDI-21-355 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
