CVE-2018-19020

Cuando CX-Supervisor (versiones 3.42 y anteriores) procesa archivos de proyecto y manipula el valor de un desplazamiento, un array puede forzar a la aplicación para que lea un valor fuera de un array.

This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of OMRON CX-Supervisor. 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 parsing of SCS files. 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 execute arbitrary code in the context of the current process.
