https://notcve.org/view.php?id=CVE-2018-14816
Advantech WebAccess 8.3.1 and earlier has several stack-based buffer overflow vulnerabilities that have been identified, which may allow an attacker to execute arbitrary code. Advantech WebAccess 8.3.1 y anteriores tiene varias vulnerabilidades de desbordamiento de búfer basado en pila que podrían permitir que un atacante ejecute código arbitrario. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability. The specific flaw exists within bwnodeip.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs process. 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. • http://www.securityfocus.com/bid/105728 http://www.securitytracker.com/id/1041939 https://ics-cert.us-cert.gov/advisories/ICSA-18-296-01%2C • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
