  3. CVE-2023-20025
A vulnerability in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, and RV082 Routers could allow an unauthenticated, remote attacker to bypass authentication on an affected device. This vulnerability is due to improper validation of user input within incoming HTTP packets. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web-based management interface. A successful exploit could allow the attacker to bypass authentication and gain root access on the underlying operating system.

Summary
  • (es) Una vulnerabilidad en la interfaz de administración basada en web de los routers Cisco Small Business serie RV042 podría permitir que un atacante remoto no autenticado omita la autenticación en el dispositivo afectado. Esta vulnerabilidad se debe a una validación incorrecta de la entrada del usuario de los paquetes HTTP entrantes. Un atacante podría aprovechar esta vulnerabilidad enviando solicitudes manipuladas a la interfaz de administración basada en web. Un exploit exitoso podría permitir al atacante obtener privilegios de superusuario en el dispositivo afectado.
