Multiple cross-site scripting (XSS) vulnerabilities in ViArt Shop Free 2.5.5, and possibly other distributions including Light, Standard, and Enterprise, allow remote attackers to inject arbitrary web script or HTML via the (1) forum_id parameter in forum.php, which is not properly handled in block_forum_topics.php, and (2) item_id parameter in reviews.php, which is not properly handled in block_reviews.php.

Directory traversal vulnerability in payments/ideal_process.php in the iDEAL transaction handler in ViArt Shopping Cart allows remote attackers to have an unknown impact via directory traversal sequences in the filename parameter to the createCertFingerprint function. NOTE: this issue is disputed by CVE because PHP encounters a fatal function-call error on a direct request for payments/ideal_process.php
