Unak-CMS SQL Injection and Cross-Site Scripting Vulnerabilities

SECUNIA ADVISORY ID:
SA20410

http://secunia.com/advisories/20410/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
Unak-CMS 1.x
http://secunia.com/product/10319/

DESCRIPTION:
Some vulnerabilities have been reported in Unak-CMS, which can be
exploited by malicious people to conduct cross-site scripting attacks
and SQL injection attacks.

1) Input passed to the "u_a" and "u_s" parameters is not properly
sanitised before being used in SQL queries. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

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

The vulnerabilities have been reported in version 1.5 RC2. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

Filter malicious characters and character sequences in a web proxy
with URL filtering capabilities.
