Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Multiple heap-based buffer overflow vulnerabilities exist caused by a lack of proper validation of the length of user-supplied data, which may allow remote code execution.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The product writes data past the end, or before the beginning, of the intended buffer.
