CVE-2016-1019:Magnitude攻击工具里的flash漏洞

上月,Proofpoint一安全研究人员发现Magnitude攻击工具里似乎出现了些新东西。于是在他们的合作下我们分析了样本并发现Magnitude EK里增加了之前存在于Adobe Flash Player的漏洞(cve-2016-1019),然后野外利用对Flash Player最近版本进行远程执行。

虽然最新版本21.0.0.197也存在这个漏洞,不过因为Adobe 在Flash Player21.0.0.182版本中引入了新的漏洞缓解方式,因此这个漏洞在这个版本中起不到什么作用。这次是Adobe处理漏洞问题的一大举动。

利用传输链做坏事

Magnitude EK更新了它的传输链。它在链里增加了一道“门”,有点像Angler EK,先收集屏幕的尺寸和色彩深度。

然后服务器为防止被用户的防毒软件发现用了另一个页面响应。

Magnitude EK通过发送JSON来双重释放这个漏洞(cve-2015-2419)和一个Flash loader。

Flash攻击

这个漏洞(cve-2015-2419)的特点是在攻击者的控制下会导致Flash内存分配器自主分配缓冲区。然后攻击者就可以在里面创建一个长度为0xffffffff的字节数组任意读写存储器。而且,在我们查看过程中发现侵入代码及其一些功能和之前HackingTeam泄露的漏洞入侵代码很相似,都是从另一个服务器下载恶意程序。
