Vulnerabilities Discovered by TRaViS

Explanation: SQL Injection occurs when an attacker manipulates input fields, such as forms or URL parameters, to execute malicious SQL queries. This can give them unauthorized access to your database, allowing them to view, modify, or delete sensitive data.

Example: An e-commerce website allows users to search for products. If the search input is not properly sanitized, an attacker could enter a SQL command like ' OR '1'='1 which could return all data from the database instead of just relevant search results.

Explanation: XSS attacks involve injecting malicious scripts into webpages, which are then executed in the browsers of other users. This can lead to data theft, session hijacking, or unauthorized actions on behalf of the user.

• Persistent XSS: The injected script is stored on the server and affects every user that accesses the targeted page. 
  Example: A social media post containing malicious code could execute when viewed by other users, capturing their session cookies.
  
  
• Reflected XSS: The malicious script is embedded in a URL and only affects users who click on that specific link.
  Example: A phishing email contains a link that, when clicked, executes a script that steals login credentials.
  
  
• DOM-based XSS: The attack manipulates the Document Object Model (DOM) on the client side rather than the server side.
  Example: A search bar on a website processes input directly in the browser, allowing an attacker to inject a script that modifies the page's content or behavior.

Explanation: This vulnerability occurs when authentication mechanisms are poorly implemented, allowing attackers to gain unauthorized access to user accounts or session data.

• Session Hijacking: Attackers can steal or manipulate session IDs to impersonate users. 
  Example: If a session ID is exposed in a URL, an attacker could use it to take over the session and perform actions as the authenticated user.
  
  
• Credential Stuffing: Attackers use automated tools to try large numbers of username and password combinations, exploiting users who reuse credentials across multiple sites. 
  Example: An attacker gains access to a list of leaked credentials from another site and uses them to access your web app, assuming users have reused passwords.
  
  
• Weak Password Policies: Insufficient password requirements make it easier for attackers to guess or brute force passwords.
  Example: Allowing users to set simple passwords like "password123" increases the risk of unauthorized access.

Explanation: APIs that are not properly secured can expose sensitive data or functionality to attackers. This can happen through insecure endpoints, lack of authentication, or poor rate limiting.

• Insecure Endpoints: Attackers can exploit open API endpoints to access data or services. 
  Example: An API endpoint allows users to retrieve account information without verifying their identity, leading to data exposure.
  
  
• Lack of Authentication: APIs that do not require proper authentication leave your system open to unauthorized access. 
  Example: An API that doesn't verify user tokens can be accessed by anyone who knows the endpoint URL.
  
  
• Poor Rate Limiting: Without limits on API requests, attackers can overwhelm your system with automated queries.
  Example: An attacker sends thousands of requests per second to an API, leading to a denial of service.

Explanation: Without comprehensive logging, detecting and responding to security incidents becomes much more difficult. This can delay critical interventions and increase the impact of an attack. 

Example: A data breach goes unnoticed for months because there were no logs of suspicious login attempts or data transfers.​

Explanation: Allowing users to upload files without proper validation can introduce malware or other harmful content into your system.

Example: A user uploads a seemingly harmless image file, but it contains malicious code that executes when the file is processed by the server.
