The simple web server that we introduce in this section was not designed or implemented with security in mind. It was written to just get the basic job done, as is the case with much software in the real world. In addition, we assume that the programmer who wrote it was not given a software requirements document, and was just simply told, Build a basic web server. You will see that our simple web server has many security vulnerabilities, even though it correctly serves documents using HTTP. We will use this web server to illustrate how it might have been designed differently. Some of its vulnerabilities will be due to design flaws, some will be due to implementation vulnerabilities, and others will be due to a combination of the two. We now present SimpleWebServer.java, a very small web server written in the Java programming language. While the following SimpleWebServer code may seem reasonably correct, and does function as a web server, it has many vulnerabilities. You will learn about its vulnerabilities in this chapter and the next. Although you can run SimpleWebServer on your machine and access it using your browser, we highly recommend that you do not, unless you have disconnected your machine from the Internet and/or are running behind a well-maintained firewall. 1 /******************************************************************************** 2 3 SimpleWebServer.java 4 5 6 This toy web server is used to illustrate security vulnerabilities. 7 This web server only supports extremely simple HTTP GET requests. 8 9 This file is also available at http://www.learnsecurity.com/ntk. 10 11 *******************************************************************************/ 12 13 package com.learnsecurity; 14

instead of the live version. It is easy to make a mistake in an SQL statement that renders the contents of an entire database useless. Using a development database instead of the production database (used for the real stuff) can save you huge headaches. At best, you will not have to restore the database from backups; at worst, it can save your job.

SimpleSite will not display a list of comments on the page itself (although you could set it up to do so if you preferred) but will instead display a link at the bottom of each page of the form that says, for example, Comments (8) where the number in parentheses is the current number of comments on that page. Users can click this link to view the list of comments. There will also be an Add Comment link so that users can add a comment directly. Figure 14-3 shows what the updated screen will look like.

Figure 14-3. The updated page view screen For this to work, you need to modify both the page controller s view() action and the template. Let s start with the view() action. You need to add a SQLAlchemy query to count the number of pages associated with the page. Add this to the end of the action just before the return statement: c.comment_count = meta.Session.query(model.Comment).filter_by(pageid=id).count()

Each database connection is represented by a QSqlDatabase object, and the connections are made via a driver. After picking a driver, you can set up the relevant properties such as hostName, databaseName, userName, and password. After the connection is set up, you have to open it before you can work with it. To avoid having to pass around the same QSqlDatabase object, the entire QtSql module has the concept of the default connection. As long as you connect to one database at a time, all the classes interacting with databases already know which connection to use. Listing 13-1 shows a connection to a MySQL server being set up and established. The process is easy. First you add a database connection using the QMYSQL driver through the static

Then modify the templates/derived/page/view.html template so the footer() def looks like this: <%def name="footer()"> ## Then add our page links <p> <a href="${h.url_for(controller='page', action='list')}">All Pages</a> | <a href="${h.url_for(controller='page', action='new')}">New Page</a> | <a href="${h.url_for(controller='page', action='edit', id=c.page.id)}">Edit Page</a> | <a href="${h.url_for(controller='page', action='delete', id=c.page.id)}">Delete Page</a> </p> ## Comment links <p> <a href="${h.url_for(pageid=c.page.id, controller='comment', action='list')}">Comments (${str(c.comment_count)})</a> | <a href="${h.url_for(pageid=c.page.id, controller='comment', action='new')}">Add Comment</a> </p> ## Include the parent footer too ${parent.footer()} </%def> Now when you view a page, you will also be able to list or add comments, and by viewing comments individually, you can edit or delete them.

QSqlDatabase::addDatabase method. Because you pass only a driver name and no connection name, it will be the default connection. The returned QSqlDatabase object is then set up. The properties for hostName, databaseName, userName, and password are set. Then the database connection is opened using the open method. If false is returned, the connection was not established. The reason for the failure is returned through a QSqlError object that you can get by using the lastError method. If true is returned, the connection has been successfully established.
