Rising Antivirus Online Scanner Insecure Method Flaw Exploit

<!–
– Rising is a popular anti-virus product around China.
– there's an insecure method flaw inside its free online scanner.
– it's quite easy to exploit the bug which leads to a remote execution.
– visit http://online.rising.com.cn/free/index.htm to install the ActiveX first.
– the demonstration below will download http://jsmith080220.googlepages.com/olupdate.zip and
launch olupdate.dll inside the package.
– you can code olupdate.dll yourself, in this case, I played with harmless calc.exe
