Descriptions

An Out-of-bounds read vulnerability in Trend Micro Apex One and Apex One as a Service could allow a local attacker to disclose sensitive information 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.

This is similar to, but not the same as CVE-2022-44648.

Una vulnerabilidad de lectura fuera de los límites en Trend Micro Apex One y Apex One as a Service podría permitir a un atacante local revelar información confidencial sobre las instalaciones afectadas. Tenga en cuenta: un atacante primero debe obtener la capacidad de ejecutar código con pocos privilegios en el sistema de destino para poder explotar esta vulnerabilidad. Esto es similar, pero no igual, a CVE-2022-44648.

This vulnerability allows local attackers to disclose sensitive information 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 User Mode Hooking Monitor Engine. 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 buffer. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of SYSTEM.
