Injection Flaws

IntroductionXML injection

injection

Injection flaws are those, that allow cyber attackers to XML injectioninject malicious code into web applications.

If an application accepts the user’s inputs and allows those inputs to access a database, shell command, or operating system commands, then that application is vulnerable to an injection flaw.

These flaws are usually the result of insufficient validation of input and insufficient filters or sanitization of user input.

Injection flaws or vulnerabilities can be very easy to detect and exploit, but they can also be extremely obscure.

Consequences of an injection attack can also run through a whole range of severity to complete system compromise.

Few Common Types Of Injection Flaws

SQL injection

SQL Injection, also referred to as SQLi, is the most common attack vector, where attackers insert malicious SQL code into a backend database to provide unauthorized access to private data.

Command injection

Under this vulnerability, arbitrary commands are being run on the host operating system on vulnerable parameters.

LDAP injection

It targets web applications by creating LDAP statements as per user input.

XPath injection

A website uses input data to construct an XPath query for XML data under this framework.

A cybercriminal can deliberately submit malformed data to either access or harm the existing XML data structure.

XML injection

When an unintended XML script is added to an existing XML script to insert malicious content to alter the intent of the application, it is known as an XML injection.

The most common type of injection flaw is SQLi. It is a potentially dangerous form of injection.

Also, to exploit the SQL injection flaw, the attacker must find the parameter that the web application passes through to the database.

The attacker will trick the web application into forwarding the malicious query to the database by carefully integrating malicious SQL commands into the contents of the parameter.

Such attacks aren’t hard to attempt and more tools are evolving to search for these vulnerabilities.

Is Your Website Vulnerable to Injection Flaws?

Your website source code review is the easiest way to assess if you’re vulnerable to injection flaws.

If your source code allows external resources to connect to your system, then you are may be a possible chance that your system is vulnerable to injection attacks.

For requesting the input data from the interpreters by external tools including system call, boot, fork, and runtime.exec, SQL queries, and any other command/syntax.

Using different ways to execute external commands, the developers must pay attention to reviewing their source code and also look for input data invoking HTTP requests for malicious action.

Effects Of Injection Flaws

Possible effects of this form of cyber attack can result in data loss, unintentional display of sensitive data, denial of service, and the perpetrator’s illegal system control.

Ways To Mitigate The Injection Flaws Efficiently

Validation

Filtering

Sanitizing And Escaping

Firewall

Patching And Update

Always Remember Basics

Conclusion

Injection flaws can manipulate the functioning of an application or database. But the consequences of such threats can be disastrous & compromise the entire application.

Overall, a better way of avoiding these attacks is to implement proper methods, such as validation, filtering, sanitizing, escaping, patching, and always remembering the basics, etc.
