近段时间由于修改一个ASP程序(有SQL注入漏洞)，在网上找了很多相关的一些防范办法，都不近人意，所以我将现在网上的一些方法综合改良了一下，写出这个ASP函数，供大家参考。
| 以下是引用片段： Function SafeRequest(ParaName) Dim ParaValue ParaValue=Request(ParaName) if IsNumeric(ParaValue) = True then SafeRequest=ParaValue exit Function elseIf Instr(LCase(ParaValue),"select ") > 0 or Instr(LCase(ParaValue),"insert ") > 0 or Instr(LCase(ParaValue),"delete from") > 0 or Instr(LCase(ParaValue),"count(") > 0 or Instr(LCase(ParaValue),"drop table") > 0 or Instr(LCase(ParaValue),"update ") > 0 or Instr(LCase(ParaValue),"truncate ") > 0 or Instr(LCase(ParaValue),"asc(") > 0 or Instr(LCase(ParaValue),"mid(") > 0 or Instr(LCase(ParaValue),"char(") > 0 or Instr(LCase(ParaValue),"xp_cmdshell") > 0 or Instr(LCase(ParaValue),"exec master") > 0 or Instr(LCase(ParaValue),"net localgroup administrators") > 0 or Instr(LCase(ParaValue)," and ") > 0 or Instr(LCase(ParaValue),"net user") > 0 or Instr(LCase(ParaValue)," or ") > 0 then Response.Write "<script language='javascript'>" Response.Write "alert('非法的请求!');" '发现SQL注入攻击提示信息 Response.Write "location.href='http://dev.yesky.com/';" '发现SQL注入攻击转跳网址 Response.Write "<script>" Response.end else SafeRequest=ParaValue End If End function |
使用SafeRequest函数替换你的Request
