Descriptions

OMRON CX-Programmer 9.78 and prior is vulnerable to an Out-of-Bounds Write, which may allow an attacker to execute arbitrary code.

OMRON CX-Programmer versiones 9.78 y anteriores, es vulnerable a una Escritura Fuera de Límites, lo que puede permitir a un atacante ejecutar código arbitrario

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 CXP files in the CX-Programmer module. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this vulnerability to execute code in the context of the current process.

*Credits: Xina1i, working with Trend Micro’s Zero Day Initiative reported these vulnerabilities to CISA.
