I have WHMCS and I use it with no problem for my hosting purposes.

Almost every 2 or 3 days, I can see a spam with malicious content submitted as a new ticket that tries to hack.

The last one was:

What are these attacks? Why don't they use any other way to attack?!!!

In my opinion it is obvious that a system like WHMCS will never be hacked by such a poor attempts. They should have of course used some functions like strip_tags and mysql_real_escape_string and other security functions.

Would any body explain why do they always select such a poor way to attack? Don't they really know that WHMCS is stronger than these low level hacks?

In fact I'd like to know that: Do these efforts differ from each other? Can they be serious? Should I be scared of these attempts?

In case you're curious, here's the source (or a copy of it) to the attacker's method: pastebin.com/yCW9vWzZ This may help also: www.wjunction.com/10-hosting-discussion/116021-boxslots-hacked-again-5.htm
As for being worried? If you are sure you follow the orthodox server security protocols, and you actively check for and fix any holes, then you should be fine. I recommend you keep a log of all of the IP addresses sending this code, and then maybe call their ISP (can be determined from ip2location.com/their.ip.address.here).

It's a robot scanning the web for WHMCS installs that are vulnerable to this attack, it's just part and parcel of running a website.
