Descriptions

Multiple vulnerabilities exist in the web-based management interface of Cisco Small Business RV Series Routers. A remote attacker could execute arbitrary commands or bypass authentication and upload files on an affected device. For more information about these vulnerabilities, see the Details section of this advisory.

Se presentan múltiples vulnerabilidades en la interfaz de administración basada en web de los enrutadores Cisco Small Business RV Series. Un atacante remoto podría ejecutar comandos arbitrarios u omitir la autenticación y cargar archivos en un dispositivo afectado. Para mayor información sobre estas vulnerabilidades, consulte la sección Detalles de este aviso

Cisco RV-series routers suffer from an authentication bypass vulnerability. The RV34X series are also affected by a command injection vulnerability in the sessionid cookie, when requesting the /upload endpoint. A combination of these issues would allow any person who is able to communicate with the web interface to run arbitrary system commands on the router as the www-data user. Vulnerable versions include RV16X/RV26X versions 1.0.01.02 and below and RV34X versions 1.0.03.20 and below.
