Overview:
rewterz has discovered a critical vulnerability in Sami FTP Server. This
vulnerability may allow a remote attacker to overwrite memory with user
controlled data and execute arbitrary code in the context of the user who
executed the Sami FTP Server.
Technical Details:
This vulnerability exists in the handling of both username and password input
provided by the user while making connection to FTP server. We chose not to
provide detailed information about the location of the vulnerability and how to
reproduce it because the author hasn't confirmed this vulnerability. We can
pass a long argument with some commands into a buffer. There is no checking of
the length of these inputs. Depending on the input, this will cause exploitable
condition.
We have confirmed the ability to execute our own code. This is a common buffer
overflow vulnerability and can be exploited easily.
