对斐讯Fir302B路由器进行的渗透测试

来源:freebuf 作者:影武者实验室 时间:2017-01-08 TAG: 我要投稿

0×00 固件发布站弱口令+sql注入

fir302b的板子还是比较友好的,拆开能直接看到GND TX RX VCC,虽然没有针脚。

我手头只有一块ttl开发板和三根杜邦线,直接连上UART:

自检结束后,能看到两处post请求,把当前的设备指纹信息、终端账号密码、云账号密码发送到了一个地址

这个url是一个固件发布站,后台存在弱口令

在查询工号处存在注入

昨天测试的时候,发现还有个spring框架的任意文件读取漏洞,今天已经修了

0×01 固件发布站SOAP-based blind xxe

抓路由器的数据包看一下完整的请求

root@kali:~# nmap -T4 -O 10.8.5.* -vv
Nmap scan report for 10.8.5.232
Host is up, received arp-response (-0.076s latency).

root@kali:~# traceroute baidu.com

root@kali:~# echo 1 >> /proc/sys/net/ipv4/ip_forward
root@kali:~# arpspoof -i eth0 -t 10.8.5.1 10.8.5.232

root@kali:~# arpspoof -i eth0 -t 10.8.5.232 10.8.5.1

root@kali:~# tcpdump -i eth0 -w victim.pcap -vv
tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 262144 bytes
^C905 packets captured
905 packets received by filter
0 packets dropped by kernel

这里是因为用的交换机,直接混杂模式抓不到包

那么扫上层网段得到路由器IP,然后找到网关,双向欺骗后,重启路由器,tcpdump抓包,等待路由器自检结束

wireshark过滤http请求得到完整数据包

发现能自定义DTD,能加载外部实体:

那么 读一下/var/log/messages

0×02 认证会话劫持漏洞

说起来这算是为了防御arp嗅探泄露cookie而产生的一种漏洞

简单的测试了一下,deauth中断client连接后,session没有立即失效,伪造client mac地址即可进入路由器
