  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2023-20026
A vulnerability in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, RV082, RV320 and RV325 Routers could allow an authenticated, remote attacker to execute arbitrary commands 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 gain root-level privileges and access unauthorized data. To exploit this vulnerability, an attacker would need to have valid administrative credentials on the affected device.

Summary (en) A vulnerability in the web-based management interface of Cisco Small Business Routers RV042 Series could allow an authenticated, remote attacker to inject arbitrary commands on an affected device. This vulnerability is due to improper validation of user input fields within incoming HTTP packets. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on an affected device with root-level privileges. To exploit these vulnerabilities, an attacker would need to have valid Administrator credentials on the affected device.

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 autenticado inyecte comandos arbitrarios en un dispositivo afectado. Esta vulnerabilidad se debe a una validación incorrecta de los campos de entrada del usuario dentro de los paquetes HTTP entrantes. Un atacante podría aprovechar esta vulnerabilidad enviando una solicitud manipulada a la interfaz de administración basada en web. Un exploit exitoso podría permitir al atacante ejecutar comandos arbitrarios en un dispositivo afectado con privilegios de nivel superusuario. Para aprovechar estas vulnerabilidades, un atacante necesitaría tener credenciales de administrador válidas en el dispositivo afectado.
