In this article, we explore vulnerabilities affecting operating systems and web applications. We explain how attackers can exploit these weaknesses to gain unauthorized access, escalate privileges, or execute arbitrary code.

​
Operating System Vulnerabilities

Operating system vulnerabilities are security flaws found in platforms such as Windows, Linux, or macOS. Attackers can leverage these vulnerabilities in various ways:
  • Privilege Escalation: Exploiting design or implementation flaws to obtain higher-level system privileges.
  • Kernel Exploitation: Targeting bugs within the OS kernel to execute arbitrary code.
Regularly updating and patching your operating systems can significantly reduce the risk of exploitation.

​
Web-Based Vulnerabilities

Web-based vulnerabilities continue to present a significant risk for modern applications. Two common examples include SQL Injection and Cross-Site Scripting (XSS).

​
SQL Injection

SQL Injection occurs when an application fails to sanitize user inputs that interact with its SQL database. This flaw allows attackers to inject malicious SQL code, which may be used in one of two ways:
  • Combined Queries: The injected code is merged with legitimate SQL queries.
  • Blind SQL Injection: The attack exploits the vulnerability without returning detailed error messages.
The image illustrates a web-based vulnerability involving SQL injection attacks, showing an attacker targeting input fields. It highlights "Blind SQLi," which exploits vulnerabilities without visible error messages.

​
Cross-Site Scripting (XSS)

Cross-Site Scripting (XSS) involves injecting malicious scripts into web pages viewed by other users. Once these scripts execute in a victim’s browser, they can:
  • Steal session tokens.
  • Perform actions on behalf of the user.
  • Hijack user interactions with the web application.
The image is about web-based vulnerabilities, specifically Cross-Site Scripting (XSS), and describes it as injecting malicious scripts into web pages viewed by other users.

Conclusion

Understanding both operating system and web-based vulnerabilities is essential for implementing robust security measures. By staying informed about these risks and prompt patching, administrators and security professionals can better protect systems against malicious exploits.
