This vulnerability exists in the ERP system due to improper validation of payment callback parameters and inadequate authentication controls

This vulnerability exists in the ERP system due to improper validation of payment callback parameters and inadequate authentication controls in API endpoint. An unauthenticated remote attacker could exploit this vulnerability by manipulating the parameter to cause the application to establish an authenticated session for an arbitrary user without valid payment verification.

Successful exploitation of this vulnerability could allow the attacker to bypass authentication and gain unauthorized access to other user accounts on the targeted system.
