The SMTP Listener of Secure Email Gateway from Cellopoint does not properly validate user input, leading to a Buffer Overflow vulnerability. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary system commands on the remote server.
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.
