CVE-2009-4048

The exploit demonstrates a denial-of-service (DoS) vulnerability in XM Easy Personal FTP Server 5.8.0 by creating over 2000 directories, which crashes the server upon reconnection and directory listing. The Python script automates the creation of directories to trigger the vulnerability.

This exploit targets CVE-2009-4048, a vulnerability in Pure-FTPd. It leverages a race condition between the APPE and DELE commands to trigger a denial-of-service (DoS) condition. The script establishes an FTP connection, sends crafted commands, and binds to a local port to exploit the flaw.
