PHP : Improper exception handling

The application performs some operation, such as database or file access, that could throw an exception. Since the application is not designed to properly handle the exception, the application could crash.

Improper handling of exceptions can introduce a variety of security problems for a web site. The most common problem is when detailed internal error messages such as stack traces, database dumps, and error codes are displayed to the user (attacker). These messages reveal implementation details that should never be revealed. Such details can provide attackers important clues on potential flaws in the site and such messages are also disturbing to normal users.
