[原文]PhpMyFactures 1.2 and earlier allows remote attackers to bypass authentication and modify data via direct requests with modified parameters to (1) /tva/ajouter_tva.php, (2) /remises/ajouter_remise.php, (3) /pays/ajouter_pays.php, (4) /pays/modifier_pays.php, (5) /produits/ajouter_cat.php, (6) /produits/ajouter_produit.php, (7) /clients/ajouter_client.php, (8) /clients/modifier_client.php. NOTE: the provenance of this information is unknown; portions of the details are obtained from third party information.
PhpMyFactures contains a flaw that may allow a remote attacker to manipulate data. The issue is due to the system not properly authenticating for access to several pages. A remote unauthenticated attacker could use this manipulate a wide variety of data in the back-end database.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
