CVE-2018-0422

Estado: ModificadaAlta (7.3)—

A vulnerability in the folder permissions of Cisco Webex Meetings client for Windows could allow an authenticated, local attacker to modify locally stored files and execute code on a targeted device with the privilege level of the user. The vulnerability is due to folder permissions that grant a user the permission to read, write, and execute files in the Webex folders. An attacker could exploit this vulnerability to write malicious files to the Webex client directory, affecting all other users of the targeted device.

Leer descripción completaMostrar menos

A successful exploit could allow a user to execute commands with elevated privileges. Attacks on single-user systems are less likely to occur, as the attack must be carried out by the user on the user's own system. Multiuser systems have a higher risk of exploitation because folder permissions have an impact on all users of the device. For an attacker to exploit this vulnerability successfully, a second user must execute the locally installed malicious file to allow remote code execution to occur.

La vulnerabilidad se debe a los permisos de carpeta que conceden a un usuario el permiso de lectura, escritura y ejecución de archivos en las carpetas de Webex. Un atacante podría explotar esta vulnerabilidad para escribir en archivos maliciosos en el directorio del cliente de Webex, afectando a todos los usuarios del dispositivo objetivo. Su explotación con éxito podría permitir que el atacante ejecute comandos con privilegios elevados. Es menos probable que ocurran ataques en sistemas monousuario, ya que el ataque lo debe llevar a cabo el usuario en el propio sistema del usuario. Los sistemas multiusuario tienen un mayor riesgo de explotación porque los permisos de carpeta afectan a todos los usuarios del dispositivo. Para que un atacante explote esta vulnerabilidad con éxito, un segundo usuario debe ejecutar el archivo malicioso instalado localmente para permitir que ocurra la ejecución remota de código."
