Description:
A vulnerability was reported in KDE Konqueror. A remote user can cause Konqueror to conduct portscans.
In response to an FTP PASV command from the target user's Konqueror client, the remote connected FTP server can return a port number and different IP address, causing the Konqueror client to connect to the specified IP address and port number.
A remote user can create a specially crafted web page that, when loaded by the target user, will cause the target user's browser to connect to a malicious FTP server and then scan the ports specified by the malicious FTP server, including scanning systems that are on the target user's internal network.
Mark at bindshell.net reported this vulnerability.
