Wed Mar 14 16:30:48 UTC 2007

Hi,

The vulnerability is there (vulnerable code):
    author = Request.QueryString("author")
    bid = Request.QueryString("bid")

    ' Check parameters
    If Not IsNumeric(bid) Then
        bid = 0
    End If
    If CInt(bid) < 0 Then
        bid = 0
    End If
    If title = "" And author = "" Then
        Call ParseError(langErrSearchNoInput)
        Call DoErrorMsg("./search.asp")
    End If

    ' Generate SQL
    sql = "SELECT * FROM posts"
    If title <> "" Then
        sql = sql & " WHERE post_title LIKE '%" & title & "%'"
    End If

    If author <> "" Then
        If InStr(sql, "WHERE") <> 0 Then
            sql = sql & " AND user_name='" & author & "'"
        Else
            sql = sql & " WHERE user_name='" & author & "'"
        End If
    End If
