CVE-2026-13268

G DATA Total Security Backup Service 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 Backup Service. By creating a symbolic link, an attacker can abuse the service to delete a file. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-28665.

Summary		(es) Vulnerabilidad de escalada de privilegios local en el enlace del Servicio de Copia de Seguridad de G DATA Total Security. Esta vulnerabilidad permite a atacantes locales escalar privilegios en instalaciones afectadas de G DATA Total Security. Un atacante debe primero obtener la capacidad de ejecutar código con privilegios bajos en el sistema objetivo para explotar esta vulnerabilidad. La falla específica existe dentro del Servicio de Copia de Seguridad. Al crear un enlace simbólico, un atacante puede abusar del servicio para eliminar un archivo. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar código arbitrario en el contexto de SYSTEM. Fue ZDI-CAN-28665.
