We rewrote our file handling code to properly escape file paths with filenames ending in a period. If you need any help setting up Cerberus FTP Server you can browse our online support resources. During our testing, we actually discovered that most applications couldn’t open or access files (including all of the popular browsers and file transfer clients we tested) that ended in a period. The release notes for every official version of Cerberus FTP Server. Without special handling in Cerberus, the operating system ignores the trailing backslash. However, the Windows operating system would actually create the file without the period. The practical implication of this behavior is that a malicious user could bypass our file extension blocking mechanism.įor example, if an administrator added “.exe” as a file extension to block from uploads, a user could upload “badfile.exe.” and it would be allowed since “.exe.” doesn’t match “.exe”. Basically, Windows will ignore the period at the end of the file path when interpreting the path. Passing that file, or a path to that file, to a Windows API call will result in the operating system trying to open or create the file without the period at the end. You might tell the operating system to create a file called “badfile.exe.”, but it will actually create “badfile.exe” – the same file, but without the period at the end. To illustrate this, passing a file named “badfile.exe.” to a Windows API call results in unexpected behavior. It turns out that file names that end in a period require special handling by the Windows operating system.

The second issue was a little more complicated. Handling File Names That End in a Period (fixed in 10.0.16) This vulnerability resulted in our team re-evaluating and re-designing how we construct our SMTP headers to prevent this and any future header injection vulnerabilities. A practical example of how this flaw could be exploited would be to add a special “reply-to” header to the public share email. The first issue was an email header bypass vulnerability. We committed the classic mistake of not properly sanitizing user input, and that omission could allow a malicious, authenticated user to craft a subject line that added additional SMTP headers to outgoing public share email messages.
