概述：无线路由器被广泛使用在工业、企业、家庭的网络环境中，无线路由器安全漏洞研究是物联网安全研究的重要领域之一。目前很多网上无线路由器漏洞分析的文章直接翻译的国外文章，但实际做起来会发现存在各种问题。本文根据实际实验，从环境搭建、模糊测试、漏洞利用三个阶段完整展现无线路由器web服务器缓存区溢出漏洞挖掘分析的详细过程。
1. 简介
无线路由器被广泛使用在工业、企业、家庭的网络环境中，无线路由器安全漏洞研究是物联网安全研究的重要领域。本文为你展现无线路由器web服务器缓存区溢出漏洞的模糊测试到漏洞利用的详细过程。
2. WRT54G漏洞分析环境建立
2.1. 建立交叉编译环境
下载musl-cross : git clone https://github.com/GregorR/musl-cross.git
在 config.sh中增加
CFLAGS="-fPIC"
TRIPLE=mipsel-linux-musl
在defs.sh中修改
LINUX_HEADERS_URL=https://kernel.org/pub/linux/kernel/v2.6/longterm/v2.6.32/linux-2.6.32.70.tar.xz in defs.sh
运行 ./build.sh
交叉编译环境将被安装在/opt/cross目录
在profile中增加
export MIPSEL_HOME=/opt/cross/mipsel-linux-musl
export PATH=$PATH: $MIPSEL_HOME/bin
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$MIPSEL_HOME/lib
export LD_LIBRARY_PATH
2.2. 安装IDA插件
3. WRT54G固件漏洞研究
3.1. 固件下载：
http://dl-sh-ocn-1.pchome.net/2s/9o/linksys_wrt54gv2_fw4007.zip?key=5df0916ed9d62e2a295dbc6dddb2ba9d&tmp=1492133581036
root@aflfuzz:~# binwalk -e WRT54GV3.1_4.00.7_US_code.bin
3.2. WRT54G httpd服务器模糊测试
在firmadyne虚拟环境运行防火墙（见《嵌入式固件自动化分析环境firmadyne使用详细教程》）。使用burpesuite测试apply.cgi请求可以导致httpd服务崩溃。说明该请求存在bug。方法：
点击start attack开始攻击，在攻击串超过10000后httpd服务器崩溃
Firmadyne控制台也显示httpd had died
3.3. 使用nvram-faker修复NVRAM
3.3.1. Qemu-mipsel虚拟运行防火墙/usr/sbin/httpd服务
为了进一步分析调试httpd服务，需要使用qemu-mipsel-static虚拟运行路由器中的httpd服务进程。（采取这个方式是因为直接在firmadyne环境里使用gdbserver实验无法远程调试）
root@aflfuzz:~/_WRT54GV3.1_4.00.7_US_code.bin.extracted/squashfs-root# chroot ./ ./qemu-mipsel-static . /usr/sbin/httpd
/dev/nvram: No such file or directory
出现错误提示
因此需要修复nvarm硬件依赖
下载
git clone https://github.com/zcutlip/nvram-faker.git
3.3.2. 修改nvram-faker增加劫持函数
原始fork函数会启动很多子进程导致程序调试复杂，所以需要劫持它，简化调试。
增加劫持get_mac_from_ip
修改nvram-faker.h文件添加fork函数
#ifndef __NVRAM_FAKER_H__
#define __NVRAM_FAKER_H__
char *nvram_get(const char *key);
int fork(void);
char *get_mac_from_ip(const char*ip);
…
#endif /* __NVRAM_FAKER_H__ */
修改nvram-faker.c添加fork、get_mac_from_ip函数
…
int fork(void)
{
return 0;
}
char *get_mac_from_ip(const char*ip)
{
char mac[]="00:50:56:C0:00:08";
char *rmac = strdup(mac);
return rmac;
}
3.3.3. 编译nvram-faker
root@aflfuzz:~/nvram-faker-master# ./buildmipsel.sh
mipsel-linux-gcc -Wall -I./contrib/inih -ggdb -DINI_MAX_LINE=2000 -DINI_USE_STACK=0 -fPIC -c -o nvram-faker.o nvram-faker.c
make -C ./contrib/inih ini.o
make[1]: 正在进入目录 `/root/nvram-faker-master/contrib/inih'
mipsel-linux-gcc -ggdb -DINI_MAX_LINE=2000 -DINI_USE_STACK=0 -fPIC -c -o ini.o ini.c
make[1]:正在离开目录 `/root/nvram-faker-master/contrib/inih'
cp ./contrib/inih/ini.o .
mipsel-linux-gcc -shared -o libnvram-faker.so nvram-faker.o ini.o -Wl,-nostdlib
root@aflfuzz:~/nvram-faker-master# ls
arch.mk ini.o nvram-faker.c~ nvram-faker.o
buildmipsel.sh libnvram-faker.so nvram-faker.h nvram.ini
buildmipsel.sh~ LICENSE.txt nvram-faker.h~ README.md
buildmips.sh Makefile nvram-faker-internal.h
contrib nvram-faker.c nvram_faker_main.c
3.3.4. 将libnvram-faker.so和同目录下的nvram.ini复制到WRT54G路由器的根文件系统中
将buildroot交叉编译环境output/host/目录下libgcc_s.so.1（因为编译libnvaram-faker.so库用到了这个共享库）文件复制到路由器二进制根目录，复制后目录结构如下：
root@aflfuzz:~/ _R6200-V1.0.0.28_1.0.24.bin.extracted/squashfs-root# ls
bin etc libnvram-faker.so nvram.ini proc sbin tmp var
dev lib mnt prepare.sh qemu-mipsel-static sys usr www
3.3.5. 写如下prepare.sh脚本修改HTTPD执行环境
HTTPD在运行时需要对/var目录下的某些文件进行操作，而这些文件是在Linux启动过程中才会产生的，因此要先删除var目录，再创建。
Prepare.sh
#!/bin/sh
rm var
mkdir var
mkdir ./var/run
mkdir ./var/tmp
touch ./var/run/lock
touch ./var/run/crod.pid
touch httpd.pid
3.4. 使用qemu-mipsel-static试运行httpd
使用sudo运行
root@aflfuzz:~# cd _WRT54GV3.1_4.00.7_US_code.bin.extracted/squashfs-rootroot@aflfuzz:~/_WRT54GV3.1_4.00.7_US_code.bin.extracted/squashfs-root#sudo chroot . ./qemu-mipsel -E LD_PRELOAD="/libnvram-faker.so" ./usr/sbin/httpd
# sudo chroot . ./qemu-mipsel -E LD_PRELOAD="/libnvram-faker.so" ./usr/sbin/httpd
LOG_HTTPD=Unknown
setsockopt(SO_SNDTIMEO): Invalid argument
setsockopt(SO_RCVTIMEO): Invalid argument
http_client_ip=Unknown
/dev/nvram: No such file or directory
http_client_mac=Unknown
/dev/nvram: No such file or directory
http_username=Unknown
http_passwd=Unknown
router_name=Unknown
web_wl_filter=Unknown
这时需要创建一些设备对象和修改nvram.ini文件
3.5. 创建硬件设备及配置文件
使用firmadyne脚本改写的
1) fixImage.sh
#!/bin/sh
# use busybox statically-compiled version of all binaries
#BUSYBOX="busybox"
# print input if not symlink, otherwise attempt to resolve symlink
resolve_link() {
TARGET=$(readlink $1)
if [ -z "$TARGET" ]; then
echo "$1"
fi
echo "$TARGET"
}
# make /etc and add some essential files
mkdir -p "$(resolve_link etc)"
if [ ! -s etc/TZ ]; then
echo "Creating etc/TZ!"
mkdir -p "$(dirname $(resolve_link etc/TZ))"
echo "EST5EDT" > "$(resolve_link etc/TZ)"
fi
if [ ! -s etc/hosts ]; then
echo "Creating etc/hosts!"
mkdir -p "$(dirname $(resolve_link etc/hosts))"
echo "127.0.0.1 localhost" > "$(resolve_link etc/hosts)"
fi
if [ ! -s etc/passwd ]; then
echo "Creating etc/passwd!"
mkdir -p "$(dirname $(resolve_link etc/passwd))"
echo "root::0:0:root:/root:/bin/sh" > "$(resolve_link etc/passwd)"
fi
# make /dev and add default device nodes if current /dev does not have greater
# than 5 device nodes
mkdir -p "$(resolve_link dev)"
FILECOUNT="$(find dev -maxdepth 1 -type b -o -type c -print | wc -l)"
if [ $FILECOUNT -lt "5" ]; then
echo "Warning: Recreating device nodes!"

chmod a+x "firmadyne/preInit.sh"
4) 修改nvram.ini
修改lan_hwaddr、lan_ipaddr，增加LOG_HTTPD等一些内容，修改后nvram.ini内容如下：

3.6. 加载/libnvram-faker.so运行httpd
不开启远程调试端口
sudo chroot ./ ./qemu-mipsel -E LD_PRELOAD="/libnvram-faker.so" ./usr/sbin/httpd
开启远程调试端口
sudo chroot ./ ./qemu-mipsel -E LD_PRELOAD="/libnvram-faker.so" -g 1234 ./usr/sbin/httpd
3.7. 使用IDA Pro远程调试
3.7.1. IDA Pro远程调试启动
1) 设置调试器选项
2) 在main函数入口设置断点
3) 附加到进程
附加成功后显示
4) 按F9继续进程
3.7.2. 构造apply cgi的请求数据包
根据3.2章节模糊测试情况，使用msf里pattern_create.rb构造apply.cgi请求的post数据，放到burpsuite里重放。Post数据构造命令如下：
root@kali:/opt/metasploit/apps/pro/msf3/tools# ./pattern_create.rb 26384
构造的post http请求如下：
POST /apply.cgi HTTP/1.1
Accept-Encoding: identity
Content-Length: 26384
Host: 10.0.0.141
Content-Type: application/x-www-form-urlencoded
