Descriptions

Three type confusion vulnerabilities exist in CX-One Versions 4.50 and prior and CX-Protocol Versions 2.0 and prior when processing project files. An attacker could use a specially crafted project file to exploit and execute code under the privileges of the application.

Existen tres vulnerabilidades de confusión de tipos en CX-One, en versiones 4.50 y anteriores, y en CX-Protocol, en versiones 2.0 y anteriores, durante el procesamiento de archivos de proyecto. 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-One CX-Protocol. 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 handling of PSW files. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to execute code in the context of the current process.
