COMMAND
Clipper
SYSTEMS AFFECTED
Anaconda Clipper 3.3 (probably others)
PROBLEM
Following is based on a UkR security team Advisory no. 11. '..'
and '/' are not filtered while processing user input, so it is
possible to enter arbitrary values to retreive files from remote
sever, which should not be accessible normally (for ex.,
/etc/passwd). Example:
http://blah.somenonexistanthost.com/cgi-bin/anacondaclip.pl?template=../../../../../../../../../../../../../../../../../../etc/passwd
SOLUTION
This will help in somewhat:
$input =~ s/[(\.\.)|\/]//g;
