WebAccess Versions 8.3.2 and prior. The application fails to properly validate the length of user-supplied data, causing a buffer overflow condition that allows for arbitrary remote code execution.
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 performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
