There is the indexing of /sitemap.xml. Which lead to a new page /index.htnl


The page consists of a gif. So I viewed the page source of the page.


So I change the hidden part of the code and an “id ” command by /cmd.php 


It worked but not as I respected to be. it gave an error and a clue to use another methodology of HTTP. So I changed the method GET to POST for the form.


Yess I found you.  Now I tried to opening /etc/passwd/

On more enumeration, I open /cmd.php and found the password of the user isw0:123456789blabla

Got the user flag going for the root flag.


Eureka !!!!!! GOT THE FLAG
