TITLE:
AnnonceScriptHP Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA23318

VERIFY ADVISORY:
http://secunia.com/advisories/23318/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data, Exposure of sensitive
information

WHERE:
>From remote

SOFTWARE:
AnnonceScriptHP 2.x
http://secunia.com/product/12879/

DESCRIPTION:
Mr_KaLiMaN has discovered several vulnerabilities in AnnonceScriptHP,
which can be exploited by malicious people to disclose sensitive data,
conduct SQL injection and conduct cross-site scripting attacks.

1) A vulnerability due to insufficient checks in
admin/admin_membre/fiche_membre.php lets unauthenticated people view
any user's password and other user details by passing the "idmembre"
parameter.

2) Input passed to the "no" parameter in voirannonce.php, "idmembre"
in admin/admin_membre/fiche_membre.php, "idannonce" in
admin/admin_annonce/okvalannonce.php and
admin/admin_annonce/changeannonce.php, and "id" in email.php is not
properly sanitised before being used in SQL queries. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation of email.php requires valid user
credentials.

3) Input passed to the "email" parameter in erreurinscription.php,
Templates/admin.dwt.php, Templates/commun.dwt.php,
Templates/membre.dwt.php, and admin/admin_config/Aide.php is not
properly sanitised before it is 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.

Successful exploitation requires that "register_globals" is enabled.

The vulnerabilities are confirmed in version 2.0 (demo). Other
versions may also be affected.

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

Restrict access to admin/admin_membre/fiche_membre.php (e.g. with
".htaccess").
