CVE-2018-8834 – OMRON CX-One CX-FLnet Node Name Heap-based Buffer Overflow Remote Code Execution Vulnerability

https://notcve.org/view.php?id=CVE-2018-8834

Parsing malformed project files in Omron CX-One versions 4.42 and prior, including the following applications: CX-FLnet versions 1.00 and prior, CX-Protocol versions 1.992 and prior, CX-Programmer versions 9.65 and prior, CX-Server versions 5.0.22 and prior, Network Configurator versions 3.63 and prior, and Switch Box Utility versions 1.68 and prior, may cause a heap-based buffer overflow. El análisis sintáctico de archivos de proyecto mal formados en Omron CX-One, en versiones 4.42 y anteriores, incluyendo las siguientes aplicaciones: CX-FLnet, en versiones 1.00 y anteriores; CX-Protocol, en versiones 1.992 y anteriores; CX-Programmer, en versiones 9.65 y anteriores; CX-Server, en versiones 5.0.22 y anteriores; Network Configurator, en versiones 3.63 y anteriores y Switch Box Utility, en versiones 1.68 y anteriores, podría provocar un desbordamiento de búfer basado en memoria dinámica (heap). This vulnerability allows remote attackers to execute arbitrary code on vulnerable 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 processing of FLN files. When parsing the Node Name field, the process does not properly validate the length of user-supplied data prior to copying it to a heap-based buffer. • https://ics-cert.us-cert.gov/advisories/ICSA-18-100-02 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
