ASP.NET Misconfiguration: Excessive Session Timeout

Abstract
An overly long authentication timeout gives attackers more time to potentially compromise user accounts.
Explanation
The longer a session stays open, the larger the window of opportunity an attacker has to compromise user accounts. While a session remains active, an attacker may be able to brute-force a user's password, crack a user's wireless encryption key, or commandeer a session from an open browser. Longer authentication timeouts can also prevent memory from being released and eventually result in a denial of service if a sufficiently large number of sessions are created.

Example 1: The following example shows ASP.NET MVC configured with an hour authentication timeout.

...
<configuration>
<system.web>
<authentication>
<forms
timeout="60" />
</authentication>
</system.web>
</configuration>
...


If the timeout attribute is not specified the authentication timeout defaults to 30 minutes.
