CVE-2019-13637

In LogMeIn join.me before 3.16.0.5505, an attacker could execute arbitrary commands on a targeted system. This vulnerability is due to unsafe search paths used by the application URI that is defined in Windows. An attacker could exploit this vulnerability by convincing a targeted user to follow a malicious link. Successful exploitation could cause the application to load libraries from the directory targeted by the URI link. The attacker could use this behavior to execute arbitrary commands on the system with the privileges of the targeted user if the attacker can place a crafted library in a directory that is accessible to the vulnerable system.

En join.me anterior a versión 3.16.0.5505 de LogMeIn, un atacante podría ejecutar comandos arbitrarios en un sistema específico. Esta vulnerabilidad es debido a rutas (paths) de búsqueda no seguras usadas por el URI de la aplicación que es definido en Windows. Un atacante podría explotar esta vulnerabilidad si convence a un usuario específico para que siga un enlace malicioso. Una explotación con éxito podría causar que la aplicación cargue bibliotecas desde el directorio destino mediante el enlace URI. El atacante podría usar este comportamiento para ejecutar comandos arbitrarios en el sistema con los privilegios del usuario víctima, si el atacante puede colocar una biblioteca diseñada en un directorio que es accesible en el sistema vulnerable.
