TITLE:
PhpMyFactures Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA20642

VERIFY ADVISORY:
http://secunia.com/advisories/20642/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
PhpMyFactures 1.x
http://secunia.com/product/10482/

DESCRIPTION:
DarkFig has discovered some vulnerabilities in PhpMyFactures, which
can be exploited by malicious people to conduct cross-site scripting
and SQL injection attacks, and to bypass certain security
restrictions.

1) Input passed to the "prefixe_dossier" parameter in
/inc/header.php, to the "msg" parameter in
/remises/ajouter_remise.php, /tva/ajouter_tva.php,
/stocks/ajouter.php, /pays/ajouter_pays.php,
/produits/ajouter_cat.php, /produits/ajouter_produit.php and
/produits/modifier_cat.php, to the "tire" parameter in
/remises/ajouter_remise.php, to the "quantite", "taux" and "date"
parameters in /stocks/ajouter.php, and to the "pays" and "prefixe"
parameters in /pays/ajouter_pays.php isn't 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 "id_pays" parameter in
/pays/modifier_pays.php, to the "id_produit", "quantite", "prix_ht"
and "date" parameters in /stocks/ajouter.php, to the "id_cat"
parameter in /produits/modifier_cat.php, and to the "id_client"
parameter in /clients/modifier_client.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 without requiring admin
logon.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

3) Access to several scripts isn't properly restricted to the logon
administrative user. This can be exploited to manipulate data in the
database without requiring a valid logon. 

The following scripts are affected.
/tva/ajouter_tva.php
/remises/ajouter_remise.php
/pays/ajouter_pays.php
/pays/modifier_pays.php
/produits/ajouter_cat.php
/produits/ajouter_produit.php
/clients/ajouter_client.php
/clients/modifier_client.php

The vulnerabilities have been confirmed in version 1.2 and also
reported in version 1.0. Other versions may also be affected.

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