现在流行的asp上传组件除了无惧的化境之外,最多的可能就是ewebEditor 和Fckeditor的上传是,但是经过测试都很难防止改名为gif和asp文件上传,在FckEditor中改名后的asp木马不能直接上传,系统会检测到 <%等字符而拒绝,但是经过修改后的asp木马再改名为gif后却可以顺利上传,如在文件前端加上许多空行,或对木马进行加密处理。当然有人会认为木马传到服务器后会被杀掉,但是做过免杀的木马却会漏网。基于这些原因,本人开发了一个可以从根本上解决这个问题的无组件上传类。经过测试常用的文件格式均可通过。做法是对上传的文件进行格式分析,不符合的格式不允许上传,这样就从根本上解决了这个问题。现贴上来请大家指教。
