Webhacking.kr 17번 문제
Written on 13번 이후로 그냥 오늘 20번까지 할까요.
문제 난이도들이 급 쉬워져서 포스팅도 짧아지게되었네요.

function sub(){ if(login.pw.value==unlock){ alert(“Password is “+unlock/10); }else { alert(“Wrong”); }}
정말 간단합니다.
sub function 내 조건은 건너뛰고, 패스워드는 “unlock/10” 이라고합니다.
unlock 의 값은 9997809307 이고 이 값을 9997809307/10하면 999780930.7입니다.
해당 값으로 flag 하면 클리어.
