    Study Notes

    Web Content Loading

    • Webpages load various content directly from a server, including HTML, CSS, JavaScript, and often images and videos.
    • Video content on typical websites is usually sourced from dedicated streaming servers, such as YouTube or Vimeo.
    • Images and pictures on webpages usually come from the website’s own server or external image hosting services.

    Information Retrieval in Browsers

    • The browser’s rendering engine determines where to fetch the necessary information to construct a webpage.
    • Browsers can collect data from third-party sites without user login credentials due to cookie use and cross-origin resource sharing.

    Awareness of Third-Party Data Fetching

    • Victims may remain unaware of their browser’s data collection from third-party sites due to the seamless integration of this process within usual browsing activities.

    Vulnerabilities and Attacks

    • Server Side Request Forgery (SSRF) occurs when a web application is vulnerable to an unauthorized request made by the server itself.
    • Developers can prevent SSRF vulnerabilities by validating and sanitizing user input, employing whitelisting strategies, and limiting what endpoints the server can reach.

    Capital One Case Study

    • The 2019 SSRF attack on Capital One led to the exposure of sensitive customer data, affecting over 100 million accounts.
    • A misconfigured web application firewall was responsible for the security breach during the attack.
    • The attacker exploited the SSRF vulnerability to gain access to Amazon S3 buckets, compromising credit card applications and other personal information.

    Importance of Addressing SSRF Vulnerabilities

    • Promptly closing SSRF vulnerabilities is crucial to prevent potential data breaches and maintain customer trust.

    Client-Side Code Execution

    • HTML and JavaScript are executed on the client side when a user visits a website, enabling interactive and dynamic content.

    Cross Site Request Forgery (CSRF) Attacks

    • Cross Site Request Forgery exploits the trust a website has in a user's browser to perform unauthorized actions on behalf of the user.
    • Anti-forgery techniques in web applications aim to protect against CSRF attacks by validating requests using tokens or similar methods.

    Potential Outcomes of CSRF Attacks

    • In a successful CSRF attack, an attacker could initiate undesirable transactions, modify account settings, or steal sensitive information.
    • Typical initiation methods for CSRF include embedding malicious links or forms in websites or emails.

    SSRF Exploitation Dynamics

    • Attackers leveraging SSRF need to identify vulnerable endpoints in the server that allow unauthorized requests to internal services or resources.
    • Techniques to prevent CSRF attacks usually involve implementing anti-CSRF tokens that confirm the authenticity of user requests.

    Characteristics of SSRF

    • A defining characteristic of SSRF is its exploitation of the web application’s trust in its server to send requests to unintended destinations.

    Role of PHP and Web Development

    • PHP primarily serves as a server-side scripting language used for dynamic content generation, database interaction, and session management in web development.

    Detection Challenges

    • Victims often struggle to detect SSRF attacks through their web browsers due to the covert nature of server-side requests and responses.

    Abbreviations and Actions in Attacks

    • CSRF is commonly abbreviated to represent Cross Site Request Forgery.
    • In a CSRF attack, an attacker typically aims to trick the user into performing transactions good for the attacker’s benefit without their knowledge.

    HTML and JavaScript Delivery

    • HTML and JavaScript code is frequently presented to the browser in the client-side layer of a website for enhanced user interactions and layout rendering.
