NcFTP client 3.1.6 and 3.1.7, when the username and password are included in an FTP URL that is provided on the command line, allows local users to obtain sensitive information via "ps aux," which displays the URL in the process list. http://marc.theaimsgroup.com/?l=bugtraq&m=108247943201685&w=2
It seems this issue was never fixed. I can still do this on FC3. I'm half tempted to say this is probably a non issue. I'm interested in what some of the other programs do which also deal with similar URLs on the command line.
This is basically a non issue. Nobody should be providing sensitive information such as this on the command line. The only way to fix this is still insecure, since there is a gap between startup and scribbling over ARGV.
