- Description
Calling tiki-check.php (via the drop down menu of control panels) causes my rented webspace to crash. Literally. First, a 500 is thrown (internal server error), and afterwards the entire webspace goes offline for a couple of minutes! Eventually it does recover, but I have no idea by what mechanism of my ISP this happens. Probably a restart of the (assumed) Docker instance.
This can possibly lead to disturbing the online presence of other customers of the same ISP, depending on the grade of encapsulation of the ISP!
Something dangerous is happening inside tiki-check.php. This must never happen, because this spells out that there is something that can lead to a DOS, either involunaterily by co-admins not aware of the danger of the function, or even by attackers who somehow manage to do whatever tiki-check.php does when this happens. Possibly even by attacking other Tikis hosted by the same ISP, if the ISPs encapsulation is weak...
I therefore propose that tiki-check.php be split up into segments that can be called individually (this eases finding the culprit) and then to have an admin configurable set of functions, so admins can disable dangerous functions.
