  2. Vulnerabilities (CVE)
  3. CVE-2021-34982
NETGEAR Multiple Routers httpd Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of multiple NETGEAR routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the httpd service, which listens on TCP port 80 by default. When parsing the strings file, 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. . Was ZDI-CAN-13709.

Summary
  • (es) Vulnerabilidad de ejecución remota de código de desbordamiento de búfer en la región stack de la memoria httpd de múltiples enrutadores de NETGEAR. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de múltiples enrutadores NETGEAR. No se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe dentro del servicio httpd, que escucha en el puerto TCP 80 de forma predeterminada. Al analizar el archivo de cadenas, el proceso no valida correctamente la longitud de los datos proporcionados por el usuario antes de copiarlos en un búfer basado en pila de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la raíz. Era ZDI-CAN-13709.
