https://notcve.org/view.php?id=CVE-2021-38389
Advantech WebAccess versions 9.02 and prior are vulnerable to a stack-based buffer overflow, which may allow an attacker to remotely execute code. Advantech WebAccess versiones 9.02 y anteriores, son vulnerables a un desbordamiento del búfer en la región stack de la memoria, que podría permitir a un atacante ejecutar código de forma remota This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of IOCTL 0x1138B. 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 Administrator. • https://us-cert.cisa.gov/ics/advisories/icsa-21-285-02 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

CVSS: 9.8EPSS: 11%CPEs: 1EXPL: 0CVE-2020-12019 – Advantech WebAccess Node Incorrect Permission Assignment Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-12019
WebAccess Node Version 8.4.4 and prior is vulnerable to a stack-based buffer overflow, which may allow an attacker to remotely execute arbitrary code. WebAccess Node versión 8.4.4 y anteriores, es vulnerable a un desbordamiento de búfer en la región stack de la memoria, que puede permitir a un atacante ejecutar código arbitrario remotamente This vulnerability allows local attackers to escalate privileges on affected installations of Advantech WebAccess Node. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the configuration of the PostgreSQL database. The issue results from incorrect permissions set on a resource used by the service. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of SYSTEM. • https://www.us-cert.gov/ics/advisories/icsa-20-161-01 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
