Keep in mind that tips mentioned in this page may not be sufficient for securing your web application. PHP overview. PHP is the most commonly used server side programming language, with 8. W3 Techs. An open source technology, PHP is unusual in that it is both a language and a web framework, with typical web framework features built in to the language. Like all web languages, there is also a large community of libraries etc. Free PHP Classes, PHP Tutorials, Download PHP Scripts, PHP articles, PHP Jobs, Hire PHP Developers, PHP Book Reviews, PHP Language OOP Materials.

All three aspects language, framework, and libraries need to be taken into consideration when trying to secure a PHP site. PHP is a grown language rather than deliberately engineered, making writing insecure PHP applications far too easy and common. Paint Shop Pro X Serial Number. If you want to use PHP securely, then you should be aware of all its pitfalls. Language issues. Weak typing. PHP is weakly typed, which means that it will automatically convert data of an incorrect type into the expected type. This feature very often masks errors by the developer or injections of unexpected data, leading to vulnerabilities see Input handling below for an example. Try to use functions and operators that do not do implicit type conversions e. Not all operators have strict versions for example greater than and less than, and many built in functions like inarray use weakly typed comparison functions by default, making it difficult to write correct code. Exceptions and error handling. Almost all PHP builtins, and many PHP libraries, do not use exceptions, but instead report errors in other ways such as via notices that allow the faulty code to carry on running. This has the effect of masking many bugs. In many other languages, and most high level languages that compete with PHP, error conditions that are caused by developer errors, or runtime errors that the developer has failed to anticipate, will cause the program to stop running, which is the safest thing to do. Consider the following code which attempts to limit access to a certain function using a database query that checks to see if the username is on a black list. SELECT COUNTid FROM blacklistedusers WHERE username username. Code for feature here. There are various runtime errors that could occur in this for example, the database connection could fail, due to a wrong password or the server being down etc., or the connection could be closed by the server after it was opened client side. In these cases, by default the mysqli functions will issue warnings or notices, but will not throw exceptions or fatal errors. This means that the code simply carries onThe variable row becomes NULL, and PHP will evaluate row0 also as NULL, and introw0 as 0, due to weak typing. Eventually the canaccessfeature function returns true, giving access to all users, whether they are on the blacklist or not. If these native database APIs are used, error checking should be added at every point. However, since this requires additional work, and is easily missed, this is insecure by default. It also requires a lot of boilerplate. This is why accessing a database should always be done by using PHP Data Objects PDO specified with the ERRMODEWARNING or ERRMODEEXCEPTION flags unless there is a clearly compelling reason to use native drivers and careful error checking. It is often best to turn up error reporting as high as possible using the. The behaviour of PHP code often depends strongly on the values of many configuration settings, including fundamental changes to things like how errors are handled. This can make it very difficult to write code that works correctly in all circumstances. Different libraries can have different expectations or requirements about these settings, making it difficult to correctly use 3rd party code. Some are mentioned below under Configuration. Unhelpful builtins. PHP comes with many built in functions, such as addslashes, mysqlescapestring and. Some of these built ins are being deprecated and removed, but due to backwards compatibility policies this takes a long time. PHP also provides an array data structure, which is used extensively in all PHP code and internally, that is a confusing mix between an array and a dictionary. This confusion can cause even experienced PHP developers to introduce critical security vulnerabilities such as Drupal SA CORE 2. Framework issues. URL routing. PHPs built in URL routing mechanism is to use files ending in. This opens up several vulnerabilities. Remote execution vulnerability for every file upload feature that does not sanitise the filename. In other words, the web server executes something instead of serving it. Ensure that when saving uploaded files, the content and filename are appropriately sanitised. Source code, including config files, are stored in publicly accessible directories along with files that are meant to be downloaded such as static assets. Misconfiguration or lack of configuration can mean that source code or config files that contain secret information can be downloaded by attackers. In other words, the web server serves a resource which should have been private or executable only. You can use. htaccess to limit access. This is not ideal, because it is insecure by default, but there is no other alternative. The URL routing mechanism is the same as the module system. This means it is often possible for attackers to use files as entry points which were not designed as such. This can open up vulnerabilities where authentication mechanisms are bypassed entirely a simple refactoring that pulls code out into a separate file can open a vulnerability. This is made particularly easy in PHP because it has globally accessible request data GET etc, so file level code can be imperative code that operates on the request, rather than needing request handling code to be within function definitions. The lack of a proper URL routing mechanism often leads to developers creating their own ad hoc methods. These are often insecure and fail to apply appropriate authorization restrictions on different request handling functionality. Input handling. Instead of treating HTTP input as simple strings, PHP will build arrays from HTTP input, at the control of the client. This can lead to confusion about data, and can easily lead to security bugs. For example, consider this simplified code from a one time nonce mechanism that might be used, for example in a password reset code. GETnonce. correctnonce getcorrectvaluesomehow. Go ahead and reset the password. Sorry, incorrect link. If an attacker uses a querystring like this. The function strcmp will then return NULL instead of throwing an exception, which would be much more useful, and then, due to weak typing and the use of the equality operator instead of the identity operator, the comparison succeeds since the expression NULL 0 is true according to PHP, and the attacker will be able to reset the password without providing a correct nonce. Exactly the same issue, combined with the confusion of PHPs array data structure, can be exploited in issues such as Drupal SA CORE 2. Template language. PHP is essentially a template language. However, it doesnt do HTML escaping by. XSS below. Other inadequacies. There are other important things that a web framework should supply, such as a. Instant My.
