VERIFY ADVISORY:
http://secunia.com/advisories/19435/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
VNews 1.x
http://secunia.com/product/9043/

DESCRIPTION:
Aliaksandr Hartsuyeu has reported some vulnerabilities in VNews,
which can be exploited by malicious users to compromise a vulnerable
system and by malicious people to conduct script insertion and SQL
injection attacks.

1) Input passed to the "loginvar" parameter in "admin/admin.php", the
"news" parameter in "news.php", and the "nom" parameter in "news.php"
isn't 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.

2) Input passed to the "autorkomentarza" and "tresckomentarza"
parameters 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.

3) Some input passed in the administration section when editing
variables in "admin/config.php" isn't properly sanitised before being
stored. This can be exploited to inject and execute arbitrary PHP
code.

Successful exploitation requires administrative privileges and that
"magic_quotes_gpc" is disabled.

The vulnerabilities have been reported in version 1.2. Other versions
may also be affected.

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