Upcoming Webinar: Focus on FTP Server Compliance

Get Your FTP Server in Compliance

Revised - Watch the Latest Webinar Recording

With the recently added rules for the Healthcare Insurance Portability and Accountability Act (HIPAA) that now holds trading partners and business associates accountable if they also handle patient data, it's a good time to review whether your FTP server is updated and ready to meet compliance requirements. Learn how to keep your data as well as trading partner files protected within your network and still allow external access without opening inbound network ports. You can also see a demo of Linoma Software's GoAnywhere™, a managed file transfer solution that includes a secure FTP server and a reverse proxy DMZ gateway with clustering and load balancing capabilities to ensure high availability.

FTP Server Security Flaw Discovered

We know that FTP has security issues that are based upon its aging design. But a new flaw, discovered by Maksymilian Arciemowicz, is creating new concerns. This new flaw is calling into question the underlying code-base implemented by literally thousands of FTP server applications.

The flaw resides in several C code libraries that call the glob() function. "Globbing" is a pervasive function that permits the use of wildcard patterns to identify file names. It's one of the most commonly used processes in transferring large numbers of files with FTP: Instead of individually selecting files, a user may select a folder or a group of files based upon a common string. The common use of *.doc or *.* are examples.

The flaw discovered by Arciemowicz relates to a feature added to C libraries in 2001. That feature - called GLOB_LIMIT - was designed to limit the amount of memory used during transfer. Because GLOB_LIMIT is not effective, it potentially allows a system's main memory to be flooded when processing certain patterns and this may, depending on the hardware used, cause the system to become very slow, cease to respond or even crash as a result.

Of course, crashing an FTP server can then permit other security violations to take place - not only on the server side. For instance, a hung FTP server that is in the midst of a conversation with a client can leave the client's data in the open. This represents a serious potential security hole for the client software itself.

In most servers, the function is implemented via libc, but some vendors have integrated the globbing feature directly into their products, with an option in the configuration settings for it to be disabled. Arciemowicz said that OpenBSD 4.7, NetBSD 5.0.2, FreeBSD 7.3 / 8.1, Oracle Sun Solaris 10 and GNU Libc (glibc) are affected. FTP and SFTP servers all tend to support globbing, so it's important to either disable globbing in the configuration of the server side, and/or to contact the software vendor about the use of this underlying function to discuss how to the function.

GoAnywhere does not have this issue as it does not use C or the GLOB_LIMIT. GoAnywhere Services is a secure file server that allows trading partners (both internal and external) to securely connect to your system and exchange files within a fully managed and audited solution. Popular file transfer and encryption standards are supported without the need for proprietary client software.
