Descriptions

A buffer overflow privilege escalation vulnerability in Trend Micro Maximum Security (Consumer) 2018 could allow a local attacker to escalate privileges on vulnerable installations due to a flaw within processing of IOCTL 0x222060 by the tmnciesc.sys driver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

Una vulnerabilidad de escalado de privilegios por desbordamiento de búfer en Trend Micro Maximum Security (Consumer) 2018 podría permitir que un atacante local escale privilegios en instalaciones vulnerables debido a un error en el procesamiento de llamadas IOCTL 0x222060 por parte del controlador tmnciesc.sys. En primer lugar, un atacante debe obtener la capacidad de ejecutar código de bajos privilegios en el sistema objetivo para explotar esta vulnerabilidad.

This vulnerability allows local attackers to escalate privileges on vulnerable installations of Trend Micro Maximum 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 processing of IOCTL 0x222060 by the tmnciesc.sys driver. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to escalate privileges to resources normally protected from the application.
