Vulnerability from variot
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 Exists in an out-of-bounds write vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. 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. Advantech WebAccess is a set of browser-based HMI/SCADA software from Advantech.
A stack buffer overflow vulnerability exists in Advantech WebAccess 9.02 and earlier
