Problem/Motivation

I looked at the code and from my understanding a replay attack scenario has quite some requirements:

1. Simpletest must have been used on a production site.
2. An attacker got into possession of a test HTTP request that the site has sent locally to itself during testing. Which is not possible for a remote attacker, so they must have access to the server already to capture requests.
3. Simpletest did not shut down correctly and failed to clean up the test directory. It has to leave a settings.php file and .htkey behind in the file system.
4. The attacker finds a weakness to break out of the child test site and get access to the database of the main site. I can't think of a way to accomplish that, but would be very curious to see creative attempts :-)

Given that at least 2. makes an attack not practical I think the timestamp check is redundant and can be removed.

    The only reference git finds for "drupal_valid_ua" is in a comment and then that was removed. Therefor, I am closing this as outdated.
