## Technical details

A business logic vulnerability exists in HCL Aftermarket EPC version 1.0.0. While the application validates the 'UserId' during initial authentication requests, it fails to perform similar validation during subsequent email-based password recovery or transmission requests. An unauthenticated remote attacker can exploit this by manipulating server responses to redirect password-containing emails to an arbitrary address. This bypasses intended access controls, leading to the disclosure of cleartext or recoverable credentials. The vulnerability is tracked as CVE-2024-23564 and has been assigned a CVSS score of 9.1.
