Code injection, also called Remote Code Execution (RCE), occurs when an attacker exploits an input validation flaw in software to introduce and execute malicious code. Code is injected in the language of the targeted application and executed by the server-side interpreter.

How does script injection work?
Script injection is security vulnerability, a serious security threat that enables an attacker to inject malicious code in the user interface elements of your Web form of data-driven Web sites. Wikipedia states, HTML/Script injection is a popular subject, commonly termed Cross-Site Scripting , or XSS .
What is a code injection attack?
Code Injection is the general term for attack types which consist of injecting code that is then interpreted/executed by the application. This type of attack exploits poor handling of untrusted data.
How does HTML injection work?
What is HTML Injection? The essence of this type of injection attack is injecting HTML code through the vulnerable parts of the website. The Malicious user sends HTML code through any vulnerable field with a purpose to change the website's design or any information, that is displayed to the user.
What is the impact of code injection vulnerability?
Injection flaws tend to be easier to discover when examining source code than via testing. Scanners and fuzzers can help find injection flaws. Injection can result in data loss or corruption, lack of accountability, or denial of access. Injection can sometimes lead to complete host takeover.
How do hackers inject code?
Code injection, also called Remote Code Execution (RCE), occurs when an attacker exploits an input validation flaw in software to introduce and execute malicious code. Code is injected in the language of the targeted application and executed by the server-side interpreter.
Why is XSS dangerous?
Stored XSS can be a very dangerous vulnerability since it can have the effect of a worm, especially when exploited on popular pages. For example imagine a message board or social media website that has a public facing page that is vulnerable to a stored XSS vulnerability, such as the profile page of the user.

What is PHP Code Injection?
Description: PHP code injection
If the user data is not strictly validated, an attacker can use crafted input to modify the code to be executed, and inject arbitrary code that will be executed by the server.
What is SQL injection attack with example?
SQL injection, also known as SQLI, is a common attack vector that uses malicious SQL code for backend database manipulation to access information that was not intended to be displayed. This information may include any number of items, including sensitive company data, user lists or private customer details.
What is the difference between HTML injection and XSS?
HTML injections (HyperText Markup Language injections) are vulnerabilities that are very similar to Cross-site Scripting (XSS). The delivery mechanisms are exactly the same but the injected content is pure HTML tags, not a script like in the case of XSS.
Can HTML be malicious?
No, it is impossible for HTML files to contain a virus – Since HTML is literally “plain text with formatting” and will never be executed with code that can cause harm. But it can still be misused in many ways, with possible threats such as phishing, masquerading, and even redirecting to download an actual virus file.
What is CSS injection?
A CSS Injection vulnerability involves the ability to inject arbitrary CSS code in the context of a trusted web site which is rendered inside a victim's browser. ... This vulnerability occurs when the application allows user-supplied CSS to interfere with the application's legitimate stylesheets.
