首先观察到提示只允许上传图片文件,那么前端的查看代码,当页面发生改变时,会调用这个checkFileExt函数来检查上传的是不是图片,我们只需要在前端将checkFileExt函数删除,就能上传一个一个非图片文件。 效果不是太好,那么直接用burp效果好: 2、服务端验证绕过(MIME 类型检测) MIME(Multipurpose Internet Mail Extensions)...
This method will check for the dot ‘.’ occurrence in the given filename. If it exists, then it will find the last position of the dot ‘.’ and return the characters after that, the characters after the last dot ‘.’ known as the file extension. Special Cases: No extension– this...
