dedecms最新版去除Power by DedeCms版权
作者/整理：deming 日期：2014-12-09
dedecms网站底部多出了一个Power by DedeCms的超链接版权信息
查看了一下织梦官方的20130607常规安全补丁更新详细信息，主要更新文件是include/dedesql.class.php变量覆盖漏洞，将这个文件下载下来打开发现第588行至592行处有一段奇怪的代码，代码如下：
$arrs1 = array(0x63,0x66,0x67,0x5f,0x70,0x6f,0x77,0x65,0x72,0x62,0x79);
$arrs2 = array(0x20,0x3c,0x61,0x20,0x68,0x72,0x65,0x66,0x3d,0x68,0x74,0x74,0x70,0x3a,0x2f,0x2f,
0x77,0x77,0x77,0x2e,0x64,0x65,0x64,0x65,0x63,0x6d,0x73,0x2e,0x63,0x6f,0x6d,0x20,0x74,0x61,0x72,
0x67,0x65,0x74,0x3d,0x27,0x5f,0x62,0x6c,0x61,0x6e,0x6b,0x27,0x3e,0x50,0x6f,0x77,0x65,0x72,0x20,
