## Technical details

HCL Aftermarket EPC version 1.0.0 is vulnerable to brute force attacks and account enumeration. The vulnerability stems from a lack of anti-automation mechanisms, such as CAPTCHA or account lockout policies, on authentication endpoints. A remote, unauthenticated attacker can leverage this to perform high-velocity automated login attempts to guess credentials or verify the existence of user accounts.
