CVE-2023-42125

Avast Premium Security Sandbox Protection Link Following Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Avast Premium 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 implementation of the sandbox feature. By creating a symbolic link, an attacker can abuse the service to create arbitrary namespace objects. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. . Was ZDI-CAN-20383.

Summary		(es) Enlace de protección de Avast Premium Security Sandbox después de una vulnerabilidad de escalada de privilegios. Esta vulnerabilidad permite a atacantes locales escalar privilegios en las instalaciones afectadas de Avast Premium Security. Un atacante primero debe obtener la capacidad de ejecutar código con pocos privilegios en el sistema de destino para poder explotar esta vulnerabilidad. La falla específica existe en la implementación de la función sandbox. Al crear un enlace simbólico, un atacante puede abusar del servicio para crear objetos de espacio de nombres arbitrarios. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar código arbitrario en el contexto de SYSTEM. Era ZDI-CAN-20383.
