CVE-2013-1924Network attack vector

Forged payment acceptance via unchecked IPN notifications

Published Feb 12, 2020 · Updated Aug 6, 2024

Access bypass in Commerce Skrill before 7.x-1.2 allows remote attackers to have forged payment notifications accepted as valid. The Moneybookers enterprise payment method processes IPN messages without sufficient access checks or required securityHash verification. Exposure requires that payment method, and successful forgery can falsely record an unverified notification as legitimate.
