SECUNIA ADVISORY ID:

http://secunia.com/advisories/25985/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
Unobtrusive AJAX Star Rating Bar 1.x
http://secunia.com/product/14740/

DESCRIPTION:
sullo has reported some vulnerabilities in Unobtrusive Ajax Star
Rating Bar, which can be exploited by malicious people to bypass
certain security restrictions or conduct cross-site scripting and SQL
injection attacks.

1) Input passed to the "q" and "t" variables in rpc.php and db.php is
not properly sanitised before being used in an SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed to the "q" variable in rpc.php is not properly
sanitised before being returned to a user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

3) Input passed to the "HTTP_REFERER" variable in db.php is not
properly sanitised before being used. This can be exploited to e.g.
bypass certain restrictions via CRLF character sequences and inject
arbitrary HTTP headers and HTTP body data in a request.

SOLUTION:
Update to version 1.2.0 or later.
