https://secunia.com/advisories/19613/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
JBook 1.x
https://secunia.com/product/9284/

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

1) Input passed to the "page" parameter in index.php is 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.

2) Input passed to the "nom" and "mail" parameters in form.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 confirmed in version 1.4. Other
versions may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
1) Mourad aka Psych0
