" <http://www.marketcircle.com/> Daylite 3 is a new generation of productivity management software. "
Bad design of password retrieval allows attackers to gain login passwords in Daylite
Vulnerable Systems: * Daylite version 1.7 and above * Daylite version 3 and prior
By connecting into the Daylite server, need to provide valid user name, but can write anything as password. After rejecting the login, Daylite will offer to send the password by email. Selecting this option sends an email containing the target user's password to the target user's configured email address.
The vulnerability exists due to the use of the attacker's SMTP server configuration. By using a network sniffer or by setting the client system's SMTP settings to a server under the control of the attacker, the password can be easily discovered. The server then allows the attacker to connect Daylite using the disclosed password.
Workaround: Assuring that all users are configured with no email address will prevent the client from attempting to send the password by email.
However, it's not clear that this will prevent a client from retrieving passwords without authentication.
