Advantech EKI-1524, EKI-1522, EKI-1521 devices through 1.21 are affected by a Stack-based Buffer Overflow vulnerability, which can be triggered by authenticated users via a crafted POST request.
Solution:
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
The product writes data past the end, or before the beginning, of the intended buffer.
