sa imi zica cineva daca a reusit sa treaca de WAF cu asa ceva..

Niciodata.. pe nici un tip de DBMS.

Exemplul acesta este un simplu mit.

Pe MySQL de exemplu nu va merge sub nici o forma. Ar putea totusi functiona doar in cazul in care filtrul respectiv va sterge /**/ din sintaxa astfel incat un/**/ion sa devina union .

Alta posibilitate nu exista.
