Serv-U < 7.3.0.1 Multiple Remote Vulnerabilities

medium Nessus Network Monitor Plugin ID 4699

Synopsis

The remote FTP server is affected by several vulnerabilities.

Description

The remote host is running Serv-U File Server, an FTP server for Windows.

The installed version of Serv-U is earlier than 7.3.0.1 and thus is reportedly affected by the following issues :
- An authenticated remote attacker can cause the service to consume all CPU time on the remote host by specifying a Windows port (eg, 'CON:') when using the STOU command provided he has write access to a directory.
- An authenticated remote attacker can overwrite or create arbitrary files via a directory traversal attack in theRNTO command.
- An authenticated remote attacker may be able to upload a file to the current Windows directory with rename by placing the destination in '\' (ie, 'My Computer').

Solution

Upgrade to version 7.3.0.1 or higher.
