Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-290.
Summary
The Payment Gateway for Idram WordPress plugin before 2.1.6 does not verify the authenticity of incoming payment notifications. Its merchant credentials used to compute the checksum are empty by default (CWE-290). An unauthenticated remote attacker can forge a payment confirmation to mark arbitrary orders as paid, or force arbitrary orders into a failed state, regardless of the gateway configuration.

Description from the CNA
The Payment Gateway for Idram WordPress plugin before 2.1.6 does not verify the authenticity of incoming payment notifications, because the merchant credentials used to compute their checksum are empty by default, allowing unauthenticated attackers to forge a valid payment confirmation and mark arbitrary orders as paid, and to force arbitrary orders into a failed state regardless of the gateway's configuration.
