####################
- Vulnerability:
####################

+--> SQL Injection
	The username, in the login form, is one-parenthesis single-quoted  
injectable. For details check
	the PoC section.

+--> Reflective XSS
	Whenever login failed, the username will be printed without  
sanitizing on the main page. This could
	be used for executing any JavaScript code.

####################
- Exploits/PoCs:
####################

+--> Exploiting The (MySQL) SQL Injection Vulnerability:
	Simply go to the login page at  
'victim.com/chillyCMS/core/show.site.php' and use
	the following vector for injecting arbitrary queries:
	    ') or $THE_QUERY or 1=('
	For example you may use following vector for extracting the pw field  
(for password) of the admin user
	    admin')and substr(pw,I,1)=('C
	replacing the I with the index of char in a loop and C with different  
characters of it. If the query result
	was true, username will be accepted and wrong password error will be  
shown. If the query result was false,
	then username will be rejected and the wrong username error will be  
shown. Allowing blind SQL injection
	to be performed.

+--> Exploiting The Reflective XSS Vulnerability:
	Use the following sample vector in the username field of the login  
page (or any other valid JavaScript
	code) => username:      <script>alert('XSS')</script>

####################
- Solution:
####################

White-list the input parameters before using them in the SQL queries,  
removing any ', \, ( characters
or more simply restrict the parameters' length to a small length.
