现阶段对题目的描述我们都可以认为是给我们的相关的提示。主要是说加密的密钥丢了，但是我们可以用COSMOS接口来发送未加密的命令。同时主办方还提供了该卫星使用的一个共享文件库kit_to.so，这里要求选手恢复与卫星的通信，其中flag就存在于传输的错误信息当中。

这个题因为用到了COSMOS这个东西，然后题目提供的COSMOS是OpenSatKit2.1套件当中的一部分，为了启动这个cosmos需要一定的环境，这里建议复现的话使用Ubuntu18.04即可，这样环境容易解决一些；
</p>
<p data-tool="mdnice编辑器" style="margin:0px 0px 16px;padding:8px 0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;clear:both;min-height:1em;font-size:15px;text-indent:30px;line-height:1.75em;visibility:visible;">
在cosmos下有个INSTALL文件，内容如下
</p>
<pre data-tool="mdnice编辑器" style="margin:10px 0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;visibility:visible;"><code style="margin:0px;padding:16px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;overflow-x:auto;color:#333333;background:#F8F8F8;display:-webkit-box;font-family:"border-radius:0px;font-size:12px;visibility:visible;">$ ./setup.sh

$ rm Gemfile.lock
$ bundle install </code></pre>
<p data-tool="mdnice编辑器" style="margin:0px 0px 16px;padding:8px 0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;clear:both;min-height:1em;font-size:15px;text-indent:30px;line-height:1.75em;">
这里本来按照执行应该是可以直接安装启动cosmos的依赖的，但是可能是版本更替了，Ubuntu的软件源默认安装的跟本题需要的依赖版本不一致导致没办法启动，这里主要是该题目需要<strong style="margin:0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;">cosmos4.4</strong>版本的，而该版本的需要用到ruby2.3版本来启动，而现在的Ubuntu18.04 apt 直接安装的已经是2.5版本无法启动，这里使用rvm来安装对应需要的ruby版本，具体命令如下
</p>
<pre data-tool="mdnice编辑器" style="margin:10px 0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;"><code style="margin:0px;padding:16px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;overflow-x:auto;color:#333333;background:#F8F8F8;display:-webkit-box;font-family:"border-radius:0px;font-size:12px;">sudo apt install rvm
rvm list known
rvm install ruby-2.3.8 --<span style="margin:0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;color:#0086B3;line-height:26px;">disable</span>-stable
rvm use 2.3.8
rvm use 2.3.8 --default
ruby -v 显示2.3.8即可 </code></pre>
<p data-tool="mdnice编辑器" style="margin:0px 0px 16px;padding:8px 0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;clear:both;min-height:1em;font-size:15px;text-indent:30px;line-height:1.75em;">
作为上述步骤，可以尝试使用如下命令查看是否能够启动COSMOS的界面
</p>
<pre data-tool="mdnice编辑器" style="margin:10px 0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;"><code style="margin:0px;padding:16px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;overflow-x:auto;color:#333333;background:#F8F8F8;display:-webkit-box;font-family:"border-radius:0px;font-size:12px;">ruby Launcher </code></pre>

正常启动应该是下面这个界面

<span style="margin:0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;letter-spacing:0px;">但是大概率是不能正常启动的，这个时候使用如下命令来安装对应依赖，不出意外的话应该是不能够直接安装完成的。</span>
</p>
<pre data-tool="mdnice编辑器" style="margin:10px 0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;"><code style="margin:0px;padding:16px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;overflow-x:auto;color:#333333;background:#F8F8F8;display:-webkit-box;font-family:"border-radius:0px;font-size:12px;">bundle install </code></pre>
<p data-tool="mdnice编辑器" style="margin:0px 0px 16px;padding:8px 0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;clear:both;min-height:1em;font-size:15px;text-indent:30px;line-height:1.75em;">
这个时候直接去官网 https://rubygems.org，查看安装不成功的依赖，直接找到对应版本进行安装即可。当所有依赖安装完成时即可正常启动cosmos界面

<pre data-tool="mdnice编辑器" style="margin:10px 0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;"><code style="margin:0px;padding:16px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;overflow-x:auto;color:#333333;background:#F8F8F8;display:-webkit-box;font-family:"border-radius:0px;font-size:12px;">INTERFACE LOCAL_CFS_INT tcpip_client_interface.rb 127.0.0.1 54321 54321 10 nil </code></pre>
<p data-tool="mdnice编辑器" style="margin:0px 0px 16px;padding:8px 0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;clear:both;min-height:1em;font-size:15px;text-indent:30px;line-height:1.75em;">
这里两个端口号分别是读写端口，需要修改为题目开头连接的端口号
</p>
<pre data-tool="mdnice编辑器" style="margin:10px 0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;"><code style="margin:0px;padding:16px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;overflow-x:auto;color:#333333;background:#F8F8F8;display:-webkit-box;font-family:"border-radius:0px;font-size:12px;">INTERFACE LOCAL_CFS_INT tcpip_client_interface.rb 127.0.0.1 19021 19021 10 nil </code></pre>

这里nc连接是19020端口，cosmos连接的是19021端口，这样cosmos发送指令在终端才会有回显
</p>
</blockquote>
<p data-tool="mdnice编辑器" style="margin:0px 0px 16px;padding:8px 0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;clear:both;min-height:1em;font-size:15px;text-indent:30px;line-height:1.75em;">
然后使用ruby 启动cosmos的图形化界面
</p>

<span style="margin:0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;letter-spacing:0px;">这时候已经成功连接上了题目</span>
</p>
<p data-tool="mdnice编辑器" style="margin:0px 0px 16px;padding:8px 0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;clear:both;min-height:1em;font-size:15px;text-indent:30px;line-height:1.75em;">
在题目回显当中有如下
</p>

结合文件名字以及cFS和COSMOS的相关知识，猜测KIT_TO可能是cFS中的服务，在COSMOS当中就是Targets界面当中的KIT_TO
</p>
<section style="margin:0px 0px 24px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;text-align:center;"><img class="rich_pages wxw-img" data-galleryid="" data-imgfileid="100019735" data-ratio="0.3216494845360825" data-s="300,640" data-src="https://mmbiz.qpic.cn/mmbiz_png/Gw8FuwXLJnT8qCvzj0Omib9lakIs9lv9E6xypTLBBghrLks3vibfThxHR1wJPb1cIl6nZtgYwCmw6UhA9I3rt5uw/640?wx_fmt=png&from=appmsg" data-type="png" data-w="485" data-original-style="" data-index="4" src="https://mmbiz.qpic.cn/mmbiz_png/Gw8FuwXLJnT8qCvzj0Omib9lakIs9lv9E6xypTLBBghrLks3vibfThxHR1wJPb1cIl6nZtgYwCmw6UhA9I3rt5uw/640?wx_fmt=png&from=appmsg&tp=wxpic&wxfrom=5&wx_lazy=1&wx_co=1" _width="485px" crossorigin="anonymous" alt="图片" data-fail="0" style="margin:0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;vertical-align:bottom;height:auto !important;visibility:visible !important;width:485px !important;" /></section>

<span style="margin:0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;letter-spacing:0px;">然后使用ida对kit_to.so文件进行逆向分析，打开发现其符号表都存在，方便查找，同时题目中说明了flag是存在于传输中的信息当中，所以在ida中直接搜索flag字符串，找到一个flag相关的函数如下</span>
</p>
<section style="margin:0px 0px 24px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;text-align:center;"><img class="rich_pages wxw-img" data-galleryid="" data-imgfileid="100019736" data-ratio="0.5416666666666666" data-s="300,640" data-src="https://mmbiz.qpic.cn/mmbiz_png/Gw8FuwXLJnT8qCvzj0Omib9lakIs9lv9E9JNibibShCvSH8nfUicV0VXhiaL60dIBoaMYuyic1Tk6jSibicgJUT05rRpMA/640?wx_fmt=png&from=appmsg" data-type="png" data-w="1080" data-original-style="" data-index="5" src="https://mmbiz.qpic.cn/mmbiz_png/Gw8FuwXLJnT8qCvzj0Omib9lakIs9lv9E9JNibibShCvSH8nfUicV0VXhiaL60dIBoaMYuyic1Tk6jSibicgJUT05rRpMA/640?wx_fmt=png&from=appmsg&tp=wxpic&wxfrom=5&wx_lazy=1&wx_co=1" _width="677px" crossorigin="anonymous" alt="图片" data-fail="0" style="margin:0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;vertical-align:bottom;height:auto !important;visibility:visible !important;width:657px !important;" /></section>

<span style="margin:0px;padding:0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;letter-spacing:0px;">代码很简单，从环境变量中获取flag，环境变量中不存在flag则将flag设置为一个默认值，然后对KitToFlagPkt进行清零，之后用strcpy将flag存放到KitToFlagPkt当中去，很明显如果我们能将KitToFlagPkt的内存dump下来就能得到flag。</span>
</p>
<p data-tool="mdnice编辑器" style="margin:0px 0px 16px;padding:8px 0px;outline:0px;max-width:100%;box-sizing:border-box !important;overflow-wrap:break-word !important;clear:both;min-height:1em;font-size:15px;text-indent:30px;line-height:1.75em;">
注意到回显信息有如下两行

猜测其中MM对应cFS的服务Memory Manager(MM)，其提供内存的dump服务。

找到cosmos的Command Sender操作，其界面如下

我们这里只需要找到对应的偏移量即可，应为给的kit_to.so的符号信息都存在，直接ida查看即可
</p>

很显然，到这里可以知道不扣掉符号表之类的信息是因为cosmos是通过对应的函数名来以及对应偏移来进行一些指令操作的。
