Title: Broker FTP Server File Listing Vulnerability
Severity: MODERATE
Description:
A vulnerability in the Broker FTP Server for Windows NT and Windows 98 allow remote users to obtain directory listings above the FTP root directory.
Although most FTP commands implemented by the Broker FTP Server, such as CWD and RETR, check whether the file or directory requested falls outside the FTP document three and fail if they do, the commands LIST and NLST do not. This allows a remote user connected to the FTP server to issue commands such as "LIST ..\..\winnt\" and "NLST ..\..\winnt\" to view the contents of directories above the FTP root.
Affected Products:
- TransSoft Broker FTP Server 3.0.0 Build 1
