Descriptions

An access of uninitialized pointer vulnerability in CX-Supervisor (Versions 3.42 and prior) could lead to type confusion when processing project files. An attacker could use a specially crafted project file to exploit and execute code under the privileges of the application.

Una vulnerabilidad de acceso de puntero no inicializado en CX-Supervisor (versiones 3.42 y anteriores) podría conducir a una confusión de tipos al procesar archivos de proyecto. Un atacante podría emplear 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 parsing of SCS files. The issue results from the lack of proper initialization of a pointer prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process.
