Depending on the parameters used, hackers can manipulate the SQL query to dump data or create new databases. Another potential threat comes from insecure file uploads. It is possible to upload any file and execute it in the current directory. This could lead to a lot of serious consequences, such as session hijacking or information stealing. An example of this could be a hacker uploading a PHP file to /admin/ and then accessing the file via a web request.
Prevention Tips:
How to Prevent SQL Injection
The first step to preventing SQL injection is to ensure there are no unsafe input parameters. Most developers should already know what this entails by now, but some may not be aware of the fact that they could have the following in their code: - user input - sensitive data - a database username and password
These types of inputs can be attacked via SQL injection. To avoid this, developers should make sure that any user submitted data is sanitized before it’s saved or used in SQL queries. Additionally, developers need to do their best to avoid using untrusted data for anything other than reporting purposes. Finally, developers should always try to use SSL wherever possible to help protect against man-in-the-middle attacks.
SQL Injection and PHP File Upload
SQL Injection is a potential threat that many websites are vulnerable to. As the name implies, it is when a hacker injects SQL code into an SQL query. This can cause the website to display data that was not intended to be shown or even create new databases. Any webpage that uses PHP, such as WordPress sites or forums, can be subject to this infection.
Another type of vulnerability that hackers could exploit with a PHP file upload is session hijacking. The user’s session will be hijacked and the hacker would have access to all their information stored in their session as well as all of their files in the current directory. This could lead to some serious consequences if they were able to gain access to this information and steal it from you.
SQL injection and improper input validation
SQL injection is a technique that uses special characters in the input to manipulate how queries are run. It can be used in a number of ways, such as changing a value or dumping data into a database. Most SQL injections can be avoided by using parameterized queries and properly sanitizing user input.
If these vulnerabilities are not fixed, it could lead to severe consequences for your business, such as stolen data or unauthorised access to sensitive information.
