https://notcve.org/view.php?id=CVE-2022-21137
Omron CX-One Versions 4.60 and prior are vulnerable to a stack-based buffer overflow while processing specific project files, which may allow an attacker to execute arbitrary code. Omron CX-One versiones 4.60 y anteriores, son vulnerables a un desbordamiento del búfer en la región stack de la memoria mientras son procesados archivos de proyectos específicos, 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 FLN files in the CX-FLnet module. 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. • https://www.cisa.gov/uscert/ics/advisories/icsa-22-006-01 https://www.zerodayinitiative.com/advisories/ZDI-22-373 https://www.zerodayinitiative.com/advisories/ZDI-22-374 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2021-27413
Omron CX-One Versions 4.60 and prior, including CX-Server Versions 5.0.29.0 and prior, are vulnerable to a stack-based buffer overflow, which may allow an attacker to execute arbitrary code. Las versiones 4.60 y anteriores de Omron CX-One, incluidas las versiones 5.0.29.0 y anteriores de CX-Server, son vulnerables a un desbordamiento del búfer basado en la pila, 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 NCI files in the CX-Position application. When parsing the B_PLC_NAME element, the process does not properly validate 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. • https://us-cert.cisa.gov/ics/advisories/icsa-21-131-01 https://www.zerodayinitiative.com/advisories/ZDI-21-588 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2020-27257
This vulnerability allows local attackers to execute arbitrary code due to the lack of proper validation of user-supplied data, which can result in a type-confusion condition in the Omron CX-One Version 4.60 and prior devices. Esta vulnerabilidad permite a atacantes locales ejecutar código arbitrario debido a una falta de comprobación apropiada de los datos suministrados por un usuario, lo que puede resultar en una condición de confusión de tipos en Omron CX-One Versión 4.60 y dispositivos anteriores 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 PSW files by the CX-Protocol application. 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. • https://us-cert.cisa.gov/ics/advisories/icsa-21-007-02 https://www.zerodayinitiative.com/advisories/ZDI-21-184 • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •

https://notcve.org/view.php?id=CVE-2020-27259
The Omron CX-One Version 4.60 and prior may allow an attacker to supply a pointer to arbitrary memory locations, which may allow an attacker to remotely execute arbitrary code. Omron CX-One versiones 4.60 y anteriores, puede permitir a un atacante suministrar un puntero a ubicaciones de memoria arbitrarias, 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 a user-supplied value prior to dereferencing it as a pointer.
