Description:
Luigi Auriemma has discovered a security issue in IPSwitch WS_FTP Server, which can be exploited by malicious people to bypass certain access restrictions and disclose sensitive information.

The security issue is caused due to an error within the WS_FTP Server Manager when processing HTTP requests for the FTPLogServer/LogViewer.asp script. This can be exploited to gain access to the log viewing interface by e.g. logging out and directly accessing the FTPLogServer/LogViewer.asp script.

The security issue is confirmed in WS_FTP Server Manager included in WS_FTP Server version 6.1. Other versions may also be affected.

Solution:
Update to version 6.1.1.
