Cross-Site Scripting (XSS) is a type of web security vulnerability that allows attackers to inject malicious scripts into web pages viewed by users. This can lead to session hijacking, credential theft, or redirection to malicious sites. XSS attacks typically exploit vulnerabilities in web applications that fail to properly sanitize user input.

Here’s an analysis of the given options:

A. SELECT username FROM accounts WHERE username='admin';-- ' AND password='password';

This is an example ofSQL Injection (SQLi)rather than XSS. It manipulates SQL queries to bypass authentication, not execute JavaScript in a user’s browser.

B. <img src="http://badfile/nothere" onerror=alert(document.cookie);>

This is a classicXSS attack.

It uses an tag with a non-existent src attribute.

The onerror event triggers when the image fails to load, executing alert(document.cookie);, which can expose session cookies.

This method is commonly used forstealing cookies or executing arbitrary scripts.

C. SELECT username FROM accounts WHERE username='XSS' ' AND password='alert("http://badurl.com")';

This isneither a valid SQL injection nor a valid XSS attack.

The syntax suggests an incorrect SQL query rather than JavaScript execution in a browser.

D. <IMG SRC="xss.png">

This isnot a valid XSS attackunless there is an additional event handler like onload, onerror, or onmouseover executing JavaScript.

By itself, it just loads an image and does not execute any malicious script.

Thus,Option Bis the correct answer as it represents a real-world XSS attack technique.

HTTP rewriting is a feature in FortiWeb that allows administrators to modify HTTP requests and responses for various purposes, including security enhancements, user experience improvements, and application functionality. One common use case for HTTP rewriting is to redirect HTTP traffic to HTTPS, ensuring that all communications between clients and the server are encrypted and secure.​

Explanation of Options:

A. To redirect HTTP to HTTPS:This is a valid reason to implement HTTP rewriting. By rewriting incoming HTTP requests to HTTPS, administrators can enforce secure connections, protecting data integrity and confidentiality. FortiWeb supports this functionality, allowing seamless redirection from HTTP to HTTPS.​

B. To implement load balancing:Load balancing is not typically achieved through HTTP rewriting. Instead, it involves distributing network traffic across multiple servers to ensure availability and reliability. FortiWeb provides load balancing features, but these are separate from HTTP rewriting capabilities.​

C. To replace a vulnerable element in a requested URL:While HTTP rewriting can modify URLs, its primary purpose is not to replace vulnerable elements within URLs. Addressing vulnerabilities typically involves input validation, sanitization, and other security measures rather than rewriting URLs.​

D. The original page has moved to a new URL:This is another valid reason to implement HTTP rewriting. When a webpage's URL changes, rewriting rules can redirect requests from the old URL to the new one, ensuring users can still access the content without encountering errors.​

In summary, both options A and D are correct reasons to implement HTTP rewriting. However, in the context of FortiWeb's functionalities, redirecting HTTP to HTTPS (option A) is a common and significant use case, as it enhances security by ensuring encrypted connections.

To enable debugging for the user tracking feature in FortiWeb, you would use the command diagnose debug application user-tracking 7. This command enables debugging for the user-tracking application and sets the debug level to 7, providing detailed logs for troubleshooting.

In the configuration, the command set sample-limit-by-ip 0 disables the sample limit for any specific IP address. This means that during the machine learning (ML) running phase, FortiWeb will not limit the number of samples it accepts from the same IP address. Setting this to 0 effectively removes any restrictions on the number of samples from a given IP address.

Bot ML models analyze multiple connections over time instead of analyzing each connection as a single unit: This is the key distinction. Bot ML models focus on analyzing patterns over a period of time, looking at behavioral patterns across multiple requests or connections from the same source to identify potential bot activity. Unlike traditional anomaly detection or API models that may focus on single connections or individual transactions, bot detection typically examines aggregated behavior to identify patterns indicative of bots, such as high-frequency requests or unusual traffic flows.

In FortiWeb's API protection mechanisms, there are distinctions between the traditional API gateway protection schema and the machine learning (ML) based API protection schema:​

Data Type Support: The API gateway protection schema has the capability to support various data types beyond just strings, allowing for more comprehensive validation and enforcement of API schemas. ​

Schema Adaptability: The ML-based API protection schema is designed to automatically learn and adapt to changes in the API structure without requiring manual intervention from administrators. This dynamic learning process enables FortiWeb to identify and protect against anomalies and potential threats in real-time.

It was upgraded to a different version after initial installation: The device has multiple partitions with different firmware versions (6.4.0 and 6.4.1), indicating that it was upgraded after the initial installation from version 6.4.0 to 6.4.1.

A self-signed certificate is useful when all the devices in your network can be configured to trust it. In this case, if your enterprise's computers trust the internal Active Directory or Certificate Authority (CA) server that signed the certificate, the self-signed certificate can be used internally for HTTPS connections without raising trust issues.

FortiWeb is primarily designed to handle HTTP and HTTPS traffic, protecting web applications from various threats. By default, when operating in reverse proxy mode, FortiWeb does not forward non-HTTP/HTTPS protocols to protected servers. However, administrators can configure FortiWeb to handle non-HTTP/HTTPS traffic differently using the config router setting command. This command allows enabling IP-based forwarding (routing) for non-HTTP/HTTPS traffic. When enabled, FortiWeb can route non-HTTP traffic through itself to the appropriate backend servers. ​

Despite this capability, any non-HTTP/HTTPS traffic that is destined directly for a FortiWeb virtual server IP address is dropped. This means that while FortiWeb can be configured to forward non-HTTP/HTTPStraffic to backend servers, it will not process non-HTTP/HTTPS traffic targeted at its own virtual server IPs. ​

Regarding IPv6 routing, FortiWeb does support IPv6 in various operation modes, including reverse proxy, offline inspection, and transparent inspection. However, enabling IPv6 routing requires specific configurations and is not automatically enabled by default. ​

XML Schema: In FortiWeb, XML protection rules allow you to define an XML Schema to validate the structure and content of incoming XML documents. This helps protect against attacks like XML injection by ensuring that only well-formed XML requests are processed.

Request URL: You can define a request URL as part of an XML protection rule to specify the URL pattern for which the rule should apply. This allows you to apply different XML protection rules to different endpoints or resources based on the URL.
