CVE-2021-1536

Estado: ModificadaAlta (7.8)—

A vulnerability in Cisco Webex Meetings Desktop App for Windows, Cisco Webex Meetings Server, Cisco Webex Network Recording Player for Windows, and Cisco Webex Teams for Windows could allow an authenticated, local attacker to perform a DLL injection attack on an affected device. To exploit this vulnerability, the attacker must have valid credentials on the Windows system. This vulnerability is due to incorrect handling of directory paths at run time.

Leer descripción completaMostrar menos

An attacker could exploit this vulnerability by inserting a configuration file in a specific path in the system, which can cause a malicious DLL file to be loaded when the application starts. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of another user account.

Para explotar esta vulnerabilidad, el atacante debe tener credenciales válidas en el sistema Windows. Esta vulnerabilidad es debido a un manejo incorrecto de las rutas de directorio en tiempo de ejecución. Un atacante podría explotar esta vulnerabilidad al insertar un archivo de configuración en una ruta específica del sistema, lo que puede causar que se cargue un archivo DLL malicioso cuando se inicie la aplicación. Una explotación con éxito podría permitir al atacante ejecutar código arbitrario en el sistema afectado con los privilegios de otra cuenta de usuario"
