Severity ?
7.8 (High) - CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
G DATA Total Security Link Following Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of G Data Total Security. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the G DATA Backup Service. By creating a symbolic link, an attacker can abuse the service to create arbitrary files. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-18749.

Esta vulnerabilidad permite a atacantes locales escalar privilegios en las instalaciones afectadas de G Data Total Security. Un atacante primero debe obtener la capacidad de ejecutar c\u00f3digo con pocos privilegios en el sistema de destino para poder aprovechar esta vulnerabilidad. El fallo espec\u00edfico existe en el servicio de copia de seguridad de G DATA. Al crear un enlace simb\u00f3lico, un atacante puede abusar del servicio para crear archivos arbitrarios. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar c\u00f3digo arbitrario en el contexto de SYSTEM. Era ZDI-CAN-18749."
