Prevent hacking attempts by blocking certain keywords in profile fields
If there was a way to block certain keywords it would be possible to stop hackers from trying to inject code by changing their profile fields.
A lot of WHMCS users are experiencing the typical...
AES_ENCRYPT(1,1), address1= (SELECT MIN(username) FROM tbladmins)
...hacking attempts and even if the WHMCS install is patched and safe it is still a worry and extra work to check that nothing was compromised, banning and deleting the user etc.
Being able to add AES_ENCRYPT as a forbidden keyword would solve this once and for all.
