####################  
- 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.
