Unauthenticated invoice disclosure via address IDOR

Published Feb 4, 2021 · Updated Aug 4, 2024

IDOR in Store-opart Op'art Devis before 4.0.2 allows remote attackers to read any user's invoice and delivery address. The change_carrier_cart action in the createquotation controller accepts attacker-selected delivery_address and invoice_address object identifiers without verifying access to the referenced records. No authentication is required, and exploitation discloses customer billing and delivery data without changing records.
