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 •
