CVSS: 7.8EPSS: 15%CPEs: 2EXPL: 0CVE-2021-27413 – Omron CX-One CX-Position NCI File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability
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') •

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.

In all versions of Omron PLC CJ Series, an attacker can send a series of specific data packets within a short period, causing a service error on the PLC Ethernet module, which in turn causes a PLC service denied result. En todas las versiones de Omron PLC CJ Series, un atacante puede enviar una serie de paquetes de datos específicos dentro de un período corto de tiempo, causando un error de servicio en el módulo Ethernet del PLC, lo que a su vez causa un resultado de denegación de servicio del PLC. • https://www.us-cert.gov/ics/advisories/icsa-20-063-03 • CWE-400: Uncontrolled Resource Consumption •
