漏洞概要以下安全公告描述了在思科UCS平台模拟器3.1(2ePE1)中发现的两个远程代码执行漏洞。思科UCS平台模拟器是捆绑到虚拟机(VM)中的Cisco UCS Manager应用程序，VM包含模拟思科统一计算系统（Cisco UCS）硬件通信的软件，思科统一计算系统（Cisco UCS）硬件由思科UCS Manager配置和管理。例如，你可以使用思科UCS平台模拟器来创建和测试支持的思科UCS配置，或者复制现有的思科UCS环境，以进行故障排除或开发。在思科UCS平台模拟器中发现的漏洞是：未经验证的远程代码执行漏洞经认证的远程代码执行漏洞一名独立的安全研究者向 Beyond Security 的 SSD 报告了该漏洞。厂商响应厂商已经发布了该漏洞的补丁，并发布以下CVE： CVE-2017-12243 漏洞详细信息未经验证的远程代码执行漏洞由于用户的输入在传递给IP/settings/ping函数时没有进行充分的过滤，导致未经身份验证的攻击者可以通过ping_NUM和ping_IP_ADDR参数注入命令，这些命令将在远程机器上以root身份执行。漏洞证明 [crayon-5a0b6be0a3646409145393/] 通过发送以上请求之一后，思科 UCS响应如下： [crayon-5a0b6be0a364d408882306/] 经认证的远程代码执行漏洞思科UCS平台模拟器容易受到格式字符串漏洞的攻击，导致远程代码执行。思科UCS平台模拟器默认运行一个SSH服务器，通过ssh登录的用户运行以下命令： [crayon-5a0b6be0a3651407130446/] 得到下面的响应： [crayon-5a0b6be0a3653646969713/] 可以看到，通过执行ssh“show sel %x”命令，我们用libsamvsh.so中的system函数覆写了_ZN7clidcos15CommandEmulator16cli_param_filterEPKc函数的入口。漏洞证明为了利用此漏洞，请按照以下说明操作：使用以下用户名和密码在vm上安装ucspe（安装全部3个网卡）：默认的ucspe用户：ucspe 默认的ucspe密码：ucspe 运行ucspe并记下ucspe的ip地址（在控制台可以看到“Connected to IP: ….”）在这次漏洞证明中，我们将会使用ip-192.168.1.43。在另一台机器上打开两个终端（例如Kali）首先，在第一个终端上执行如下操作：创建poc目录，将poc4_ucspe_3.1.2e.py放入poc目录，然后将当前目录改为poc目录创建fifo1： [crayon-5a0b6be0a3656341006860/] 创建输出目录： [crayon-5a0b6be0a3658354860561/] … Continue reading SSD安全公告-思科UCS平台模拟器远程代
