Ipswitch WS_FTP Server Manager before 6.1.1, and possibly other Ipswitch products, allows remote attackers to bypass authentication and read logs via a logLogout action to FTPLogServer/login.asp followed by a request to FTPLogServer/LogViewer.asp with the localhostnull account name.
Ipswitch WS_FTP Server Manager 6.1.0.0 and earlier, and possibly other Ipswitch products, might allow remote attackers to read the contents of custom ASP files in WSFTPSVR/ via a request with an appended dot character.
The Logging Server (ftplogsrv.exe) 7.9.14.0 and earlier in IPSwitch WS_FTP 6.1 allows remote attackers to cause a denial of service (loss of responsiveness) via a large number of large packets to port 5151/udp, which causes the listening socket to terminate and prevents log commands from being recorded, a different vulnerability than CVE-2007-3823.
Cross-site scripting (XSS) vulnerability in Ipswitch WS_FTP allows remote attackers to inject arbitrary web script or HTML via arguments to a valid command, which is not properly handled when it is displayed by the view log option in the administration interface. NOTE: this can be leveraged to create a new admin account.
