About the script injection Singapore

Injections are a very popular security concern in the World Wide Web. In fact, these injections describe particular practices where the performer –the hacker- inserts some entities in the web page code in order to create a breach then alter the content in one way or another. Among these practices, the script injection ranks as a harmful injection. In fact, this injection differs from the other types of injections by its nature and the outcomes. The truth is that it is a genius way to hack the vulnerable websites. The following lines are destined to present this injection and to know more about it.

Introducing the script injection:

The script injections describe the use of particular vulnerabilities found on the data-driven websites, the websites that interact with the users through forms, to introduce some code in order to corrupt the user interface. These injections are possible when the website is not designed to block these attacks or it is regularly revised for bugs and vulnerabilities. Forums and social media, among others, are the most platforms to these injections since they allow everyone to post texts. This can be due to poor coding practices by a freelance web designer Singapore.

Script injections use particular HTML tags and can be performed on almost all the scripting languages, but they are most common on JavaScript codes. However, corrupting PHP and HTML codes is also possible.

Performing a script injection:

The script injections are performed by inserting particular tags within the text field. The entry will then be processed and executed by the browser. The common tags used in this process are:

  • <HTML> : is the main tag that defines the HTML
  • <EMBED>: it defines the source of an external container or plugin.
  • <LINK>: it allows importing an external file commonly an external style sheet.
  • <BODY>: the tag that separates the visible elements of the HTML document from the invisible elements of the HEAD tag.
  • <IMG>: defines an image to include on the definite position.
  • <SCRIPT>: this tag introduces the script lines along with the type of scripting; commonly it introduces JavaScript and CSS codes.
  • <META>: this tag is used to introduce the meta elements within the head section. They are not visible to the users but they are critical for the browser and the search engine.

This been said, the injection will be performed by typing in the form a text including the desired injection code. The model is as follow:

Some regular text <TAG>code to inject </TAG> some regular text

Preventing script injections:

There are many ways to prevent the script injections, the most common way is to parse the “<>” symbols by creating control modules that will check the entered text before submitting them for the processing and execution modules. However, it is always necessary to check the website code source for vulnerabilities.


The script injections are real threats to the user’s privacy. They are able to perform malicious operations on the running machine. The reality is, these injections work better on the client-side and are supposed to alter the website popularity.  There are some other types of injections that are able to alter the server itself and these indeed are the real struggle.
