~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
What?: Hole in WebWho+, a whois cgi.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Version(s)?: v1.1
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Exploit!:
WebWho+ v1.1 checks for shell escape
characters in its 'command' parameter,
but what keeps us from changing the pre
seleted, default TLD options.
WebWho+ v1.1 does NOT check for shell
espace characters in its 'type'(TLD)
peremeter which is what is being
exploited.
The exploit is available to download via:
http://hhp.perlx.com/ourexploits/hhp-webwho.pl
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Fix?:
Download a secure, shell espace character
parsing whois common gateway interface
from:
http://cgi.resourceindex.com/Programs_and_
Scripts/Perl/Internet_Utilities/Whois/
Read:
http://hhp.perlx.com/ouradvisories/hhp-Whois.txt
before deciding which is secure.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shouts to all of hhp.
