Descriptions
This vulnerability allows local attackers to disclose sensitive information on affected installations of TeamViewer. 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 TeamViewer service. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated array. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-13818.
Esta vulnerabilidad permite a atacantes locales revelar información confidencial en las instalaciones afectadas de TeamViewer. Un atacante debe obtener primero la capacidad de ejecutar código con pocos privilegios en el sistema objetivo para poder explotar esta vulnerabilidad. El fallo específico se presenta en el servicio TeamViewer. El problema es debido a que no son comprobados apropiadamente los datos suministrados por el usuario, lo que puede resultar en una lectura más allá del final de una matriz asignada. Un atacante puede aprovechar esto junto con otras vulnerabilidades para ejecutar código arbitrario en el contexto de SYSTEM. Fue ZDI-CAN-13818
