当我们发现
ASP
网站被扫描有注入点,该怎么办?是不是很着急啊,试试这三种方法吧
:
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

中方法需要你自己建个数据库表
