CVE-2018-0422 (GCVE-0-2018-0422)

Vulnerability from cvelistv5 – Published: 2018-10-05 14:00 – Updated: 2024-11-26 14:45
VLAI?
Summary
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. 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 ejecuci\u00f3n de archivos en las carpetas de Webex. Un atacante podr\u00eda explotar esta vulnerabilidad para escribir en archivos maliciosos en el directorio del cliente de Webex, afectando a todos los usuarios del dispositivo objetivo. Su explotaci\u00f3n con \u00e9xito podr\u00eda 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 explotaci\u00f3n porque los permisos de carpeta afectan a todos los usuarios del dispositivo.
