Inadequate access control in Hiperdino’s REST v1.0 API. The public endpoint ‘customer/check’ could allow an authenticated attacker to enter a telephone number or an email address. When the value entered belongs to a registered customer, the service returns the associated information (email address and telephone number). No authentication is required beyond a static bearer token, and there is no rate limiting or generic error handling. Successful exploitation of this vulnerability could allow a remote attacker to enumerate a user’s contact details, although this would require obtaining a valid static bearer token, constituting an information disclosure vulnerability.
