high Nessus Plugin ID 35690


The remote FTP server is affected by a SQL injection vulnerability.


The remote host is using ProFTPD, a free FTP server for Unix and Linux.

For example, a remote attacker can bypass authentication using a specially crafted username containing a percent sign character ('%'), a single quote, and SQL code.
