CVE: CVE-2015-3306  
BID: 74238  
OSVDB: 120834  


### Background

ProFTPD is free FTP Server software for Unix and Linux platforms. 

### Problem

The mod_copy extension, if enabled in ProFTPD, allows unauthenticated attackers to read and write arbitrary files using the `**SITE CPFR**` and `**SITE CPTO**` commands. This can lead to arbitrary command execution if the system also runs a web server supporting PHP. 

### Resolution

Upgrade to ProFTPD 1.3.5a or 1.3.6rc1 or higher, or install a package update from your Linux vendor.
