Well I had about 3 advisories I was working on but my HD died and this was the only thing I could salvage. The vendor's patch is also contained below in a url.
[ Cgi Security Advisory #5 ] firstname.lastname@example.org VirtualCart Shopping Cart
Found April 2001
Public release June 2001
Vendor Contacted: April 2001
Script Effected: VirtualCart Shopping Cart Price: $199.00 for a single user license
Versions: All versions appear to be effected
Platforms: Unix, Linux, NT
Vendor Patch: http://www.cgisecurity.net/advisory/patch/VirtualCatalog.tar.gz
The problem lies in a file called CatalogMgr.pl. The template variable does no validation checking and due to this remote command execution is possible as the uid of the webserver. (Usually user www or nobody)
The following request listed below would allow grabbing of the scripts own sourcecode.
http://host/cgi-bin/CatalogMgr.pl?cartID=<valid-id>&template=CatalogMgr.pl (Note: Paths may vary)
The vendor has been contacted about this security issue. Check the vendor webpage for futher updates or use the vendor patch provided above towards the top of this advisory.
One quick solution to fix the remote command execution would be to put this script into "Taint mode". This is done my modifying the path to perl at the very top of this script. Simply change #!/usr/bin/perl to #!/usr/bin/perl -T.
It is also noted that the vendor found 3 other holes after we contacted them and the patch above fixes those holes as well.
