Descriptions

An Out-of-Bounds access vulnerability in Trend Micro Apex One could allow a local attacker to create a specially crafted message to cause memory corruption on a certain service process which could lead to local privilege escalation on affected installations. Please note: 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 acceso fuera de límites en Trend Micro Apex One podría permitir a un atacante local crear un mensaje especialmente diseñado para causar la corrupción de la memoria en un determinado proceso de servicio que podría conllevar a una escalada de privilegios local en las instalaciones afectadas. Nota: un atacante debe obtener primero la capacidad de ejecutar código poco privilegiado en el sistema de destino para poder explotar esta vulnerabilidad

This vulnerability allows local attackers to escalate privileges on affected installations of Trend Micro Apex One Security Agent. 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 Apex One NT Listener service. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM.
