VERIFY ADVISORY:
http://secunia.com/advisories/21853/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
KorviBlog 1.x
http://secunia.com/product/11920/

DESCRIPTION:
cdg393 has discovered some vulnerabilities in KorviBlog, which can be
exploited by malicious people to conduct script insertion attacks.

Input passed to the "prenom", "emailFrom", and "body" form field
parameters in livre_or.php is not properly sanitised before being
used. This can be exploited to insert arbitrary HTML and script code,
which is executed in a user's browser session in context of an
affected site when the malicious data is viewed.

The vulnerabilities have been confirmed in version 1.3.0. Other
versions may also be affected.

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