AVEVA InTouch 2014 R2 SP1 and prior, InTouch 2017, InTouch 2017 Update 1, and InTouch 2017 Update 2 allow an unauthenticated user to send a specially crafted packet that could overflow the buffer on a locale not using a dot floating point separator. Exploitation could allow remote code execution under the privileges of the InTouch View process.
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.
