Hackers can use program commands to gain access to databases. This process is known as SQL injection. While information regarding these vulnerabilities is not new, there may be types of SQL injection you are not aware exist. Four SQL injection vulnerabilities you most likely are not aware of include: default database names, .net, Boolean-based injection and dynamic database queries.
WordPress helps to make creating blogs and websites easy for those who are not programming experts. However, these sites are not impenetrable to SQL injections or other vulnerabilities. One problem that can leave website owners open to an SQL attack is WordPress’ tendency to create default database titles. When the website is created the databases that are originally established have default titles. This is so that the user can go in and create their own names for each database. Users who do not change those titles later are leaving their website vulnerable. Hackers will know to check for this because they know that many users have a tendency to leave the default database names in place.
Many website owners may be aware of the SQL injection vulnerabilities of Java. This is because Sun has published many articles on the vulnerabilities and how to prevent them. But Java is not the only language that is vulnerable. .Net, ColdFusion and other programming languages also have potential issues with SQL injections. Your company needs to audit your web applications to make sure that you find and remove any coding vulnerabilities created by .net or other languages.
If database queries include the verification of multiple true false statements then your website may be vulnerable to SQL injection. These Boolean-based vulnerabilities are present because of the complex entries that are allowed for database statements. By simplifying queries and parameters companies can easily remove this vulnerability from their website.
Dynamic Database Queries
When creating complex database queries you can leave your company database vulnerable to SQL injection. The more complex a query is the more avenues a hacker has to exploit the commands and use them to their own devices. Often dynamic database queries are created in Drupal and other programming languages but parameters are not often preset. By simplifying queries or setting parameters companies can make their websites left vulnerable.
SQL injections remain one of the top 10 threats to web applications. This is because many business owners are not aware of all the different vulnerabilities that may already exist on their websites. By creating a security audit to look for default database,.net, Boolean and dynamic vulnerabilities companies can tighten their web application security and protect their websites and their client’s privileged information. Speak with your IT department to determine how your company is protecting its websites and web applications from SQL injections and other threats. Also make sure that there is a security maintenance schedule in place in an attempt to remain one step ahead of hackers. One audit when a web application is launched is not enough to help adequately protect a company’s website.
