Different Types of Web Application Vulnerabilities
Web application vulnerabilities come in various forms, each with their unique characteristics and potential impacts. Here are some common types:
-
Injection Flaws: These vulnerabilities occur when unfiltered data is passed to an interpreter as part of a command or query. Attackers can use these flaws to trick the interpreter and gain unauthorized access to data.
-
Cross-Site Scripting (XSS): XSS vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users. These scripts can steal sensitive information, such as login credentials, and deliver it to the attacker.
-
Cross-Site Request Forgery (CSRF): In a CSRF attack, an attacker tricks a victim into performing actions on their behalf on a web application in which they’re authenticated.
-
Security Misconfiguration: This type of vulnerability arises when security settings are defined, implemented, and maintained inadequately.
-
Insecure Direct Object References (IDOR): IDOR vulnerabilities occur when an application exposes a reference to an internal implementation object. Attackers can manipulate these references to gain unauthorized access to data.
| Vulnerability Type | Description |
|---|---|
| Injection Flaws | Flaws that allow attackers to inject malicious data |
| Cross-Site Scripting (XSS) | Vulnerabilities that allow attackers to inject malicious scripts |
| Cross-Site Request Forgery (CSRF) | Attacks that trick users into performing unwanted actions |
| Security Misconfiguration | Occurs due to inadequate security settings |
| Insecure Direct Object References (IDOR) | Vulnerabilities due to exposed internal object references |
