It would be unfair not to discuss one of the most critical types of attacks, as every major attack takes place in the wild, that is the source of some serious safety breaches today.
In this blog, we’ll discuss Injection attacks which let the threat actors inject or insert malicious code into a system through attacks on a certain application are discussed.
When an interpreter is used by the Web application, there is a very high chance of a web application being vulnerable to injection attacks.
The principal idea behind an injection attack is that a request or command should be submitted to the program interpreter so that whatever the attacker enters the application is read by the interpreter and performed to rob, alter or kill data, system or other critical assets of the victims. The attacker is the target of the attack.
The most serious and oldest web application security problem is an injection.
It has been at the top of the OWASP list for several years of top 10 web application vulnerabilities. Attackers can write custom attack scripts and execute the scripts on the target system by adding them to web apps that are not properly developed.
In many different script languages, like Python, Perl, and SQL, the attack scripts can be written. Adverse people use injection attacks to steal information from employees stored in an organization’s databases, personal health information such as a patient’s allergies, a patient’s doctor or a patient’s drug, and banking financial information.
Credit/debit card information or user’s online banking site credentials may be contained in the financial information. The attackers can either directly use this information or sell all information and earn money from it to other buyers.
Some injection attacks are examples of executing commands that use the SQL language to speak backend databases, use external programs through shell commands, execute OS commands, and so on. SQL Injection is called the attack using the SQL language. Cross-Site Scripting (XSS) is another kind of injection attack.
The Cross-Site Scripting and SQL injection are both extremely common. In legacy web applications these attacks are particularly common. There are numerous tools and exploits that attackers can use, exploit and access sensitive information. These two vulnerabilities are known to allow even a script kiddie to use the available information on how to hack the systems by SQL or Cross-Site Scripting.

More types of attacks are carried out on targets by attackers. These include CRLF-injection, which can lead to Cross-Site Scripting, host header injections leading to password reset and cache poisoning, code-injection which could lead to complete system damage and system damage, OS command injection, e-mail injection for attackers to spam relay and information disclosure, XPath injection that causes information disclosure, and authentication bypass and LDAP injection that results in authentication bypass, privilege escalation and information disclosure.
The attack against Bell in Canada is a significant example of a SQL injection attack. It was a high – profile attack and caused over 40,000 records to be violated.
