TITLE:
CzarNews Script Insertion and SQL Injection Vulnerabilities

SECUNIA ADVISORY ID:
SA19541

VERIFY ADVISORY:
http://secunia.com/advisories/19541/

CRITICAL:
Moderately critical

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

WHERE:
From remote

SOFTWARE:
CzarNews 1.x
http://secunia.com/product/4829/

DESCRIPTION:
Aliaksandr Hartsuyeu has reported some vulnerabilities in CzarNews,
which can be exploited by malicious people to conduct script
insertion and SQL injection attacks.

1) Input passed to the "email" parameter in news.php isn't properly
sanitised before being used. This can be exploited to inject
arbitrary HTML and script code, which will be executed in a user's
browser session in context of an affected site when the malicious
user data is viewed.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

2) Input passed to the "usern" parameter in cn_auth.php, the "passw"
parameter in cn_auth.php, the "s" parameter in news.php, and the "a"
parameter in dpost.php is not properly sanitised before being used in
a SQL query. This can be exploited to manipulate SQL queries by
injecting arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerabilities have been reported in version 1.14. Other
versions may also be affected.

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