Descriptions

Several use after free vulnerabilities have been identified in CX-Supervisor (Versions 3.42 and prior). When processing project files, the application fails to check if it is referencing freed memory. An attacker could use a specially crafted project file to exploit and execute code under the privileges of the application.

Se han identificado varias vulnerabilidades de uso de memoria previamente liberada en CX-Supervisor, en sus versiones 3.42 y anteriores. Cuando se procesan archivos de proyecto, la aplicación no comprueba correctamente si está referenciando memoria liberada. Un atacante podría usar un archivo de proyecto especialmente manipulado para explotar y ejecutar código con los privilegios de la aplicación.

This vulnerability allows remote attackers to execute arbitrary code 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 processing of project files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process.
