TITLE:
Annuaire (Directory) "COMMENTAIRE" Script Insertion

SECUNIA ADVISORY ID:
SA19548

VERIFY ADVISORY:
http://secunia.com/advisories/19548/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Exposure of system information

WHERE:
From remote

SOFTWARE:
Annuaire (Directory) 1.x
http://secunia.com/product/9223/

DESCRIPTION:
Brian has discovered a vulnerability in Annuaire (Directory), which
can be exploited by malicious people to conduct script insertion
attacks.

Input passed to the "COMMENTAIRE" parameter in inscription.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.

It is also possible to disclose the full path to certain scripts by
accessing them directly.

The vulnerability has been confirmed in version 1.0. Other versions
may also be affected.

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

Use another product.

PROVIDED AND/OR DISCOVERED BY:
Brian
