我现在对百度的新聊天工具进行了稍微深入的分析,再下一步的分析工作就是在汇编调试里面展开的了。先说下我发现的可能威胁:
9 z5 p' W6 {7 v% D1、Swf文件跨站漏洞
/ Z* S1 f) x9 \' Y7 ]& h$ q% C在Baidu Hi 的安装文件夹里的MovieData文件夹里面有3个swf文件,分别是loginCarton.swf,videoConnectingBig.swf和videoConnectingSmall.swf。其中,loginCarton.swf的可能别利用漏洞最大,这点上百度不如腾讯,没有做好swf文件的内嵌工作,让swf文件暴露在外面。病毒可以感染并放入恶意的swf文件来覆盖他们。loginCarton.swf是baiduhi的启动画面,这是非常危险的,因为swf木马在网上非常流行。还有,病毒要获取这个目录非常简单,只要以system来读取注册表就好,路径会保存在注册表的[HKEY_LOCAL_MACHINE\SOFTWARE\3D SoftWare]下的"path"键值里面,如果修改注册表,人为改变该键值,可能引发更大的危机!

2、自动升级漏洞1 w5 v% A, H+ Y* I! Y+ ?# m* ?8 H
该漏洞目前没有测试,不过应该将来会盛行的。因为目前大家的Baidu HI都是最新版,不需要升级。将来如果需要升级的时候,这个漏洞就很危险了。Baidu Hi 的升级文件在AutoUpdate文件夹里面,

BaiduHiUpdate.exe文件通过调用config.ini文件来升级,我们来看config.ini文件的代码:/ p" S3 ?3 m' e% X

看来使用的是下载http://update.im.baidu.com/AutoUpdate/AutoUpdate.xml这个文件,我下载下来打开一看,这个文件和AutoUpdate文件夹里面的那个AutoUpdate.xml文件内容相同。代码都是如下的:

s' l m- h0 s' t- _* q通过AutoUpdate.xml文件来下载http://update.im.baidu.com/AutoUpdate/updater48-49.cab ,我们可以通过构造恶意的config.ini,然后让程序下载我们构造的恶意AutoUpdate.xml,再让程序通过AutoUpdate.xml下载恶意构造好的cab安装包,释放。还是危害挺大的!, |" H' a9 z% K8 a2 x: d
最后忠告大家,不要下载除官方以外任何地方的Baidu Hi !否则后够可能很严重,这次我发现的这两个漏洞的利用说容易也容易,说不容易也不容易,本人如上所说只是一点肤浅之见,没什么技术含量,只是觉得软件搞这么明文不好。提醒大家小心一点而已,没有别的意图,更没有哗众取宠的意思。 |
