I am in the process of setting up another server (Windows Server 2008 R2) and have move these programs over. The programs run on a schedule and run fine on my current production server running Windows Server 2003. More alerts and articles: Log into the LiveSecurity Archive.I have a simple program that sends and retrieves files via FTP using edtFtpnet/PRO(.NET). What did you think of this alert? Let us know at. This alert was researched and written by Corey Nachreiner, CISSP. ISS X-Force Advisory on IIS FTP Vulnerability. ![]() Microsoft has released patches to fix this vulnerability References: This attack leverages seemingly normal FTP response traffic. Solution Path:ĭownload, test, and deploy the appropriate IIS patches immediately, or let Windows Automatic Update do it for you. Being a critical server update, we highly recommend you test it on non-production servers before pushing it to your real web site. Whether or not you are using the IIS FTP service, we still recommend you download, test and install this update as soon as you can. Researchers have already publicly released Proof-of-Concept (PoC) exploit code demonstrating the DoS version of this flaw. If you are one of those administrators, you should consider this flaw a serious risk. That said, many administrators do enable IIS’s FTP service in order to give web administrators an easy way to update their web sites. You are only vulnerable to this attack if you have specifically installed and started this service. However, IIS does not install or start the IIS FTP service by default. An attacker does not have to authenticate to your FTP server to launch this attack. ![]() By sending such a malformed FTP command, an attacker could exploit this vulnerability to either put your FTP server into a Denial of Service (DoS) state, or to gain complete control of it. Specifically, the IIS FTP service suffers from a buffer overflow vulnerability involving the way it handles a specially crafted FTP commands (or more specifically, specially encoded characters in an FTP response). In a security bulletin released today as part of Patch Day, Microsoft describes a serious vulnerability that affects the optional FTP server that comes with the latest versions of IIS. Internet Information Services (IIS) is the popular web and ftp server that ships with all server versions of Windows.
