ASP网站被扫描有注入点,该怎么办?如何解决!

试试这三种方法:

第一种:

squery=lcase(Request.ServerVariables("QUERY_STRING"))

sURL=lcase(Request.ServerVariables("HTTP_HOST"))

SQL_injdata =":|;|>|<|--|sp_|xp_|\|dir|cmd|^|(|)|+|$|'|copy|format|and|exec|insert|select|delete|update|count|*|%|chr|mid|master|truncate|char|declare"

SQL_inj = split(SQL_Injdata,"|")

For SQL_Data=0 To Ubound(SQL_inj)

if instr(squery&sURL,Sql_Inj(Sql_DATA))>0 Then

Response.Write "SQL通用防注入系统"

Response.end

end if

next

第二种:

SQL_injdata =":|;|>|<|--|sp_|xp_|\|dir|cmd|^|(|)|+|$|'|copy|format|and|exec|insert|select|delete|update|count|*|%|chr|mid|master|truncate|char|declare"

SQL_inj = split(SQL_Injdata,"|")

If Request.QueryString<>"" Then

For Each SQL_Get In Request.QueryString

For SQL_Data=0 To Ubound(SQL_inj)

if instr(Request.QueryString(SQL_Get),Sql_Inj(Sql_DATA))>0 Then

Response.Write "SQL通用防注入系统"

Response.end

end if

next

Next

End If

If Request.Form<>"" Then

For Each Sql_Post In Request.Form

For SQL_Data=0 To Ubound(SQL_inj)

if instr(Request.Form(Sql_Post),Sql_Inj(Sql_DATA))>0 Then

Response.Write "SQL通用防注入系统"

Response.end

end if

next

next

end if

第三种

'--------写入数据库----------头-----

Str_db.close

Set Str_db = Nothing

'--------写入数据库----------尾-----

Response.Write "<Script

Language=JavaScript>alert('请不要在参数中包含非法字符尝试注入!');</Script>"

Response.Write "非法操作!系统做了如下记录:<br>"

Response.Write "操作IP:"&Request.ServerVariables("REMOTE_ADDR")&"<br>"

Response.Write "操作时间:"&Now&"<br>"

Response.Write "操作页面:"&Request.ServerVariables("URL")&"<br>"

Response.Write "提交方式:POST<br>"

Response.Write "提交参数:"&Str_Post&"<br>"

Response.Write "提交数据:"&Request.Form(Str_Post)

Response.End

End If

Next

Next

End If

'----------------------------------

'--------GET部份-------------------

If Request.QueryString<>"" Then

For Each Str_Get In Request.QueryString

For Str_Xh=0 To Ubound(Str_Inf)

If Instr(LCase(Request.QueryString(Str_Get)),Str_Inf(Str_Xh))<>0 Then

'--------写入数据库----------头-----

Str_dbstr="DBQ="+server.mappath("SqlIn.mdb")+";DefaultDir=;DRIVER={Microsoft

Set Str_db=Server.CreateObject("ADODB.CONNECTION")

Str_db.Execute("insert into

SqlIn(Sqlin_IP,SqlIn_Web,SqlIn_FS,SqlIn_CS,SqlIn_SJ) values('"&Request.ServerVariables("REMOTE_ADDR")&"','"&Request.ServerVariables("URL")&"','GET','"&Str_Get&"','"&replace(Request.QueryString(Str_Get),"'","''")&"')")

Str_db.close

Set Str_db = Nothing

'--------写入数据库----------尾-----

Response.Write "<Script

Language=JavaScript>alert('请不要在参数中包含非法字符尝试注入!);</Script>"

Response.Write "非法操作!系统做了如下记录:<br>"

Response.Write "操作IP:"&Request.ServerVariables("REMOTE_ADDR")&"<br>"

Response.Write "操作时间:"&Now&"<br>"

Response.Write "操作页面:"&Request.ServerVariables("URL")&"<br>"

Response.Write "提交方式:GET<br>"

Response.Write "提交参数:"&Str_Get&"<br>"

Response.Write "提交数据:"&Request.QueryString(Str_Get)

Response.End

End If

Next

Next

End If

第3中方法需要你自己建个数据库表
