view-source - ugly hole in the view-source cgi script

Subject: view-source

I've just found a pretty ugly hole in view-source cgi-shell script.

This script, which can be found  on some httpd distributions and
in SCO Skunkware cdroms, is designed to display a given document
located in $DOCUMENT_ROOT/$1 (where $DOCUMENT_ROOT is an
environment variable set by the server).

Unhopefully view-source does not properly check the arguments.

It is therefore possible to display any file on systems where
view-source is world executable by sending something like


Obviously this kind of so-called cgi has nothing to do in your cgi-bin
directory... Maybe a day cgi will be secure ;)
