Hello all,i got a question: a friend of mine was analysing some code and found a thing like following
| || $a=preg_replace('#\/\*.*\*\/#sU','',$a); if(preg_match('#[^0-9]#',$a)) die(); so i was wondering if you can bypass this?since the first regex tries to avoud comments like /**/ but it bypassable there should be a way to get through the numeric check.
is there? i cant figure it out! thanks all cheers | ------------------------------------------------------------------------ Securing Apache Web Server with thawte Digital Certificate In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.
