An issue was discovered in Italtel Embrace 1.6.4. The server does not properly handle application errors. In some cases, this leads to a disclosure of information about the server. An unauthenticated user is able craft specific requests in order to make the application generate an error. Inside an error message, some information about the server is revealed, such as the absolute path of the source code of the application. This kind of information can help an attacker to perform other attacks against the system. This can be exploited without authentication.
Weakness
The product generates an error message that includes sensitive information about its environment, users, or associated data.

Potential Mitigations
- Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended). The messages should not reveal the methods that were used to determine the error. Attackers can use detailed information to refine or optimize their original attack, thereby increasing their chances of success.
- If errors must be captured in some detail, record them in log messages, but consider what could occur if the log messages can be viewed by attackers. Highly sensitive information such as passwords should never be saved to log files.
- Avoid inconsistent messaging that might accidentally tip off an attacker about internal state, such as whether a user account exists or not.
