CVE-2018-11338

Estado: ModificadaAlta (7.5)—

Intuit Lacerte 2017 for Windows in a client/server environment transfers the entire customer list in cleartext over SMB, which allows attackers to (1) obtain sensitive information by sniffing the network or (2) conduct man-in-the-middle (MITM) attacks via unspecified vectors. The customer list contains each customer's full name, social security number (SSN), address, job title, phone number, Email address, spouse's phone/Email address, and other sensitive information. After the client software authenticates to the server database, the server sends the customer list. There is no need for further exploitation as all sensitive data is exposed. This vulnerability was validated on Intuit Lacerte 2017, however older versions of Lacerte may be vulnerable.

La lista de clientes contiene, de cada cliente, el nombre completo, número de la Seguridad Social (SSN), dirección, puesto de trabajo, número de teléfono, dirección de email, teléfono/email del cónyuge, además de otro tipo de información sensible. Una vez el software cliente se autentica en la base de datos del servidor, el servidor envía la lista de clientes. No se necesita más explotación, ya que se exponen todos los datos sensibles. La vulnerabilidad fue validada en Intuit Lacerte 2017, aunque otras versiones de Lacerte podrían ser también vulnerables."
