Descriptions

A privilege escalation vulnerability was reported in Lenovo Service Bridge prior to version 5.0.2.17 that could allow operating system commands to be executed if a specially crafted link is visited.

Se informó una vulnerabilidad de escalada de privilegios en Lenovo Service Bridge antes de la versión 5.0.2.17 que podría permitir la ejecución de comandos del sistema operativo si se visita un enlace especialmente manipulado.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Lenovo Service Bridge. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the LscShim module. When parsing a crafted URL, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the current user.
