110/tcp  open     pop3                 pop3服务是邮件服务。一种通信协议！
139/tcp  open     netbios-ssn          139端口一般开放的都是文件共享服务，和445端口一起搭配使用！
143/tcp  open     imap                 143端口，它是一种用于电子邮件客户端和邮件服务器之间的通信协议。
445/tcp  open     microsoft-ds         445端口，smb服务                       netbios-ssn Samba smbd 4.3.11-Ubuntu (workgroup: WORKGROUP)
993/tcp  open     imaps                993端口，它是一种通过SSL或TLS加密保护的安全IMAP通信协议
995/tcp  open     pop3s                995端口，通常用于POP3S（POP3 Secure）服务，它是一种通过SSL或TLS加密保护的安全POP3通信协议
8080/tcp open     http-proxy           8080端口，通常用于HTTP代理服务。开放的8080端口表示系统上运行着HTTP代理服务器，允许客户端通过该端口进行HTTP请求的中继。

说明靶机运行者POP3S服务器！开着8080端口表示靶机运行着http代理服务器！

它有效！
如果您通过web浏览器看到此页面，则表示您已成功设置Tomcat。祝贺
这是默认的Tomcat主页。它可以在本地文件系统上找到：/var/lib/tomcat7/webapps/ROOT/index.html
Tomcat7的老手们可能会很高兴地了解到，Tomcat的此系统实例与CATALINA_HOME一起安装在/usr/share/Tomcat7中，CATALINA_BASE安装在/var/lib/Tomcat 7中，遵循/usr/share/doc/Tomcat7-common/RUNNING.txt.gz中的规则。
如果您还没有安装以下软件包，您可能会考虑安装：
tomcat7docs：这个包安装了一个web应用程序，该应用程序允许在本地浏览tomcat7文档。安装后，您可以单击此处访问它。
tomcat7示例：此包安装了一个web应用程序，该应用程序允许访问Tomcat7Servlet和JSP示例。安装后，您可以单击此处访问它。
tomcat7 admin：这个包安装了两个web应用程序，可以帮助管理这个Tomcat实例。安装后，您可以访问管理器网络应用程序和主机管理器网络程序。
注意：出于安全原因，manager-webapp仅限于角色为“manager-gui”的用户使用。

！！！主机管理器Web应用程序仅限于角色为“admin gui”的用户。用户是在/etc/tomcat7/tomcat-Users.xml中定义的。

8080端口开放的是tomcat服务。版本是7.0.52

It's annoying, but we repeat this over and over again: cyber hygiene is extremely important. Please stop setting silly passwords that will get cracked with any decent password list.
Once, we found the password "password", quite literally sticking on a post-it in front of an employee's desk! As silly as it may be, the employee pleaded for mercy when we threatened to fire her.
No fluffy bunnies for those who set insecure passwords and endanger the enterprise.

Hi! Congratulations on being able to root MERCY.

The author feels bittersweet about this box. On one hand, it was a box designed as a dedication to the sufferance put through by the Offensive Security team for PWK. I thought I would pay it forward by creating a vulnerable machine too. This is not meant to be a particularly difficult machine, but is meant to bring you through a good number of enumerative steps through a variety of techniques.

The author would also like to thank a great friend who he always teases as "plead for mercy". She has been awesome. The author, in particular, appreciates her great heart, candour, and her willingness to listen to the author's rants and troubles. The author will stay forever grateful for her presence. She never needed to be this friendly to the author.

The author, as "plead for mercy" knows, is terrible at any sort of dedication or gifting, and so the best the author could do, I guess, is a little present, which explains the hostname of this box. (You might also have been pleading for mercy trying to root this box, considering its design.)

You'll always be remembered, "plead for mercy", and Offensive Security, for making me plead for mercy!

Congratulations, once again, for you TRIED HARDER!

Regards,
The Author

你好祝贺您能够根除MERCY。
作者对这个盒子感到苦乐参半。一方面，这是一个盒子，旨在纪念PWK的进攻安全团队所经历的苦难。我想我也会通过制造一台易受攻击的机器来支付这笔钱。这并不是一台特别困难的机器，而是通过各种技术让您完成大量列举步骤。
作者还要感谢一位好朋友，他总是调侃他“求饶”。她太棒了。作者尤其欣赏她那颗伟大的心、坦率的态度，以及她愿意倾听作者的咆哮和烦恼。作者将永远感激她的光临。她从来没有必要对作者如此友好。
正如“求饶”所知，作者在任何形式的奉献或礼物方面都很糟糕，所以我想，作者能做的最好的事情就是送一份小礼物，这就解释了这个盒子的主机名。（考虑到这个盒子的设计，你可能也在乞求宽恕，试图根除它。）
你将永远被铭记，“求饶”和“进攻安全”，因为你让我求饶！
再次祝贺你更加努力！
当做
作者
