Descriptions

The Omron CX-One Version 4.60 and prior is vulnerable to a stack-based buffer overflow, which may allow an attacker to remotely execute arbitrary code.

El Omron CX-One versiones 4.60 y anteriores es vulnerable a un desbordamiento del búfer en la región stack de la memoria, lo que puede permitir a un atacante ejecutar código arbitrario remotamente

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Omron CX-One. 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 NCI files by the CX-Position application. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
