Local Vulnerability Lab ConfigurationTesting exploit techniques against production infrastructure is illegal and unethical. To safely analyze file upload vulnerabilities, a localized sandbox environment is required. Using a lightweight cloud instance with Docker ensures rapid deployment without environmental conflicts.docker pull squ1rrel/vulne ...

SQL injection represents the most critical risk in web application security, often resulting in full compromise of backend data stores. Modern web applications rely on databases to store user accounts, preferences, content, and nearly all persistant information. Instead of generating static pages for each user, server-side scripts construct dyn ...

CSRF (Cross-Site Request Forgery) attacks force authenticated users to submit unintended requests to web applications where they maintain active sessions. Unlike XSS attacks that steal credentials, CSRF exploits the trust relationship between the browser and the server. When a user authenticates, the server establishes a session stored in brows ...

Viewing Page Source with Restricted Access Some websites may disable the right-click context menu to prevent users from viewing the page source. To view the HTML source code, press Ctrl+U (or Cmd+Option+U on Mac) directly in the browser. Developers often hide sensitive data like flags within HTML comments. <!-- Flag: FLAG{hidden_in_comment} ...

Bulk Backup File Leak Scanner This utility scans target web domains for exposed backup archive files. It reads a list of target URLs from tar.txt, appends common backup file names to each base URL, and validates leaks by checking the response's Content-Type header against known archive MIME types. Vulnerable ednpoints are written to bfvul.txt. ...

Cross-Site Request Forgery (CSRF), often pronounced "sea-surf", is a type of malicious exploit where unauthorized commands are transmitted from a user that the web application trusts. Attackers trick a user's browser into sending a forged request to a vulnerable web application where the user is currently authenticated. Since request ...

Go SSTI Fundamentals Go's template injection vulnerability allows attackers to execute arbitrary code by manipulating template rendering, potentially bypassing security restrictions like HTTPOnly cookies. Template Rendering Go templates use {{}} syntax for rendering. Consider this basic example: type Product struct { Name string Quantit ...

This section covers fundamental concepts in frontend development related to communication, essential for interviews in 2023. It delves into server-side rendering (SSR), client-side rendering (CSR), HTTP protocols, caching mechanisms, asynchronous operations, cross-origin resource sharing (CORS), and web security. Server-Side Rendering (SSR) vs. ...
