Vulnerability Title
ProFTPD 1.3.3c Backdoor Command Execution
Source: CVE Program / CVE List V5
Vulnerability Description
A malicious backdoor was embedded in the official ProFTPD 1.3.3c source tarball distributed between November 28 and December 2, 2010. The backdoor implements a hidden FTP command trigger that, when invoked, causes the server to execute arbitrary shell commands with root privileges. This allows remote, unauthenticated attackers to run any OS command on the FTP server host.
