CGI Script Center's Auction Weaver does not verify the validity of the value in the variable 'fromfile'. Therefore it is possible to perform arbitrary commands on a remote system under the UID of the http daemon by altering the variable 'fromfile'.

## Auction Weaver 1.02 / Only confirmed with LITE
##        -  Proof of Concept exploit -
##
## CGI Script Center have just released an update
## of Auction Weaver due to security reasons - I
## suggest that you spend some more time securing

##
## This exploit will spawn a xterm from $target
## to $attacker.
##
## This exploit will not work on hosts running
## Auction Weaver on NT, due to the xterm call.

Remote / Network Access Input Manipulation

Exploit Public Third-party Verified

- 漏洞描述

Auction Weaver Lite contains a flaw that allows a remote attacker to execute arbitrary commands. The issue is due to the auctionweaver.pl script not properly sanitizing input to the "formfield" variable. By manipulating the input provided to the variable, an attacker can provide arbitray commands that will be executed with the privilege of the web server.
