Dynamic Reviewer

With Dynamic Reviewer Safe-PenTest module, you can inspect your Web Application, REST API, SOAP Services, App Engines and Micro-Services during running, directly using your Browser, in non-invasive way.

DAST-Penetration Testing made easy

The following installation options are available:

• Web App. You can install it at your premises, installable in any host OS supporting Docker.

• Team Reviewer Plugin. BlackBox DAST plugin. Team Reviewer pre-installed is required.

• Cloud App. Like a local installed app, it provides various Usage Modes and Connection Modes.

Its special Safe-PenTest feature, allowing to explore vulnerabilities in your Web Applications, at the same time to keeping them securely. No need of Backups before PenTest, we guarantee our tool will keep your system and database integrity. 

You can import third-party results from Security Scanners, Host Scanners and Proof-of-Exploits tools. Their results will be correlated automatically and a unified Enterprise Report is generated.

Dynamic Reviewer DAST provides a robust and stable framework for Web Application Security Testing, suitable for all Security Analysts, QA and Developers with False Positives and False Negatives support, offering an easy-to-use Web GUI, Advanced Scan and Enterprise Reporting capabilities.

Usage Modes

Dynamic Reviewer Provides two usage modes:

• Black Box mode. It is placed in the role of the average hacker, with no internal knowledge of the target system. Testers using Dynamic Reviewer are not provided with any architecture diagrams or source code that is not publicly available. Dynamic Reviewer determines the vulnerabilities in a system that are exploitable from outside the network.
  This means that Black-Box penetration testing relies on dynamic analysis of currently running programs and systems within the target network.
  Dynamic Reviewer follows the OWASP Web Security Testing Guide, chapter 4. Web Application Security Testing.
  Further, Dynamic Reviewer analyzes in deep the client-side code (Ajax, DOM, JavaScript, TypeScript, etc.) discovering the largest number of client-side vulnerabilities in the market.

• White Box mode. [Cloud only] It performs Authentication before starting the scan. It provides the following Login modes:

  • Form-Based Authentication: login with User and Password as Web form, You can configure more than one user, they will be tested all.

  • JSON-Based Authentication: submit a JSON object with credentials

  • Tokern-Based Authentication: You can modify the request headers for inserting tokens

  • Script-Based Authentication: upload and execute a custom script used to login

Connection Modes

Both on premises and Cloud installations can connect to the target Web Application in different modes:

• Direct. Dynamic Reviewer will reach the target Web Application using a Direct connection to Internet

• Through Proxy. For reaching the target Web Application you need a proxy. You can configure the Proxy URI, Proxy TCP Port, Proxy User and Proxy Password

• SSH Tunnelling. A temporary SSH key will be automatically generated for the current Scan. The User can download it and execute the commands shown in the screen. It will create a SSH Tunnel to reach the target Web Application.

Findings

Once Scan is terminated, you have a list of Findings. You can:

• Suppress a Finding Category (example: all Blind SQL Injection issues)

• Suppress one or more Findings inside a Category

• Add Comments to the entire scan, to a Finding Category, to a single Finding

• Modify, Delete, change Severity tag, Merge Findings

• Import Results from third-party tools

• Export Combined Results in PDF, HTML, JSON, CSV, Excel and Word format

• Add Evidences to the Findings

You can drill-down to each Finding category:

Each Category groups a bunch of vulnerablities found in the virtual Attacks:

We call such Attacks ‘virtual’ because Dynamic Reviewer does not really execute the Attack/Exploit, but simulate it only.

Further, instead of declaring hundreds or even thousands of vulnerabilities you can focus of their categories, for a smarter Vulnerability Management.

Security Scanners

Further the above listed tools, Dynamic Reviewer provides its own Security Scan Engine, but you can also add results coming from third-party Security Scanners in order to cover possible False Negatives.

We currently support a number of 3rd-party Security Scanners.

Each Security Scanner makes different fields available.

In order to be able to combine output from multiple tools, our Plugin Manager lets you map between the fields provided by each Security Scanner and those you care about for your report.

It is up to you to purchase and manage the required Security Scanner’s License in case of you are using a Commercial Product.

Our tool imports the results only, without running your Security Scanner.

Client-Side scanning

Dynamic Reviewer includes an integrated, real browser environment in order to provide sufficient coverage to modern web applications which make use of technologies such as HTML5, JavaScript, DOM manipulation, AJAX, etc.

In essence, this turns Dynamic Reviewer into a DOM and JavaScript debugger, allowing it to monitor DOM events and JavaScript data and execution flows. As a result, not only can the system trigger and identify DOM-based issues, but it will accompany them with a great deal of information regarding the state of the page at the time.

Relevant information include:

• Page DOM, as HTML code.

  • With a list of DOM transitions required to restore the state of the page to the one at the time it was logged.

• Original DOM (i.e. prior to the action that caused the page to be logged), as HTML code.

  • With a list of DOM transitions.

• Data-flow sinks -- Each sink is a JS method which received a tainted argument.

  • Parent object of the method (ex.:DOMWindow).

  • Method signature (ex.:decodeURIComponent()).

  • Arguments list.

    • With the identified taint located recursively in the included objects.

  • Method source code.

  • JS stacktrace.

• Execution flow sinks -- Each sink is a successfully executed JS payload, as injected by the security checks.

  • Includes a JS stacktrace.

• JavaScript stack-traces include:

  • Method names.

  • Method locations.

  • Method source codes.

  • Argument lists.

• Compatible with ES5 and ES6

• Integrated with Wapplyzer

• A bunch of frameworks are supported, like Cordova/Phonegap and Node.js

In essence, you have access to roughly the same information that your favorite debugger (for example, FireBug) would provide, as if you had set a breakpoint to take place at the right time for identifying an issue.

DOM Security Issues

The list of DOM Security Issues found by Dynamic Reviewer are:

Configuration options include:

• Adjustable pool-size, i.e. the amount of browser workers to utilize.

• Timeout for each job.

• Worker TTL counted in jobs -- Workers which exceed the TTL have their browser process re-spawned.

• Ability to disable loading images.

• Adjustable screen width and height.

  • Can be used to analyze responsive and mobile applications.

• Ability to wait until certain elements appear in the page.

• Configurable local storage data.

Coverage

• The system can provide great coverage to modern web applications due to its integrated browser environment. This allows it to interact with complex applications that make heavy use of client-side code (like JavaScript) just like a human would.

  In addition to that, it also knows about which browser state changes the application has been programmed to handle and is able to trigger them programmatically in order to provide coverage for a full set of possible scenarios.

  By inspecting all possible pages and their states (when using client-side code) Dynamic Reviewer is able to extract and audit the following elements and their inputs:

• Forms

  • Along with ones that require interaction via a real browser due to DOM events.

  • User-interface Forms

    • Input and button groups which don't belong to an HTML<form>element but are instead associated via JS code.

  • User-interface Inputs

    • Orphan<input>elements with associated DOM events.

  • Links

    • Along with ones that have client-side parameters in their fragment, i.e.:http://example.com/#/?param=val&param2=val2

    • With support for rewrite rules.

  • Link Templates -- Allowing for extraction of arbitrary inputs from generic paths, based on user-supplied templates -- useful when rewrite rules are not available.

    • Along with ones that have client-side parameters in their URL fragments, i.e.:http://example.com/#/param/val/param2/val2

  • Cookies

  • Headers

  • Generic client-side elements which have associated DOM events.

  • AJAX-request parameters.

  • JSON request data.

  • XML request data.

Web Security Issues

Dynamic Reviewer runs testing to identify all of the major web application security vulnerabilities, such as SQL Injection, Cross-Site Scripting, Cross Site Request Forgery, and more. Dynamic Reviewer has an ever growing list of tests that are run against the application and APIs to identify potential security vulnerabilities.

Dynamic Reviewer provides the following HTTP passive and active scan rules which find specific vulnerabilities. Dynamic Reviewer can discover the following OWASP ZAP Web Security Issues:

Note that these are examples of the alerts raised - many rules include different details depending on the exact problem encountered. For example, it covers also: Text4Shell (CVE-2022-42889), Insufficient Site Isolation Against Spectre Vulnerability

Passive scans

Thay review all HTTP requests and responses from the application, looking for indicators of security vulnerabilities. These scans do not change anything about the requests.

Passive Fingerprinting

Whenever Dynamic Reviewer obtains a fingerprint from the observed traffic, passing through any firewall, it identifies the Operating System and obtain some ancillary data needed for other analysis tasks.

For TCP/IP, the tool fingerprints the client-originating SYN packet and the first SYN+ACK response from the server, paying attention to factors such as the ordering of TCP options, the relation between maximum segment size and window size, the progression of TCP timestamps, and the state of about a dozen possible implementation quirks (e.g. non-zero values in "must be zero" fields). The metrics used for application-level traffic vary from one module to another; where possible, the tool relies on signals such as the ordering or syntax of HTTP headers or SMTP commands, rather than any declarative statements such as User-Agent. Application-level fingerprinting modules currently support HTTP, SMTP, FTP, POP3, IMAP, SSH, and SSL/TLS. Some of its capabilities include:

- Highly scalable and extremely fast identification of the operating system and software on both endpoints of a vanilla TCP connection - especially in settings where NMap probes are blocked, too slow, unreliable, or would simply set off alarms,

- Measurement of system uptime and network hookup, distance (including topology behind NAT or packet filters), and so on.

- Automated detection of connection sharing / NAT, load balancing, and application-level proxying setups.

- Detection of dishonest clients / servers that forge declarative statements such as X-Mailer or User-Agent.

Active scans

On the other hand, they will create and modify requests being sent to the application, sending test requests that will surface vulnerabilities that would not be caught in a passive scan.

Active scans are definitely a better way to test for vulnerabilities in your application, as the test suite injects requests that will surface vulnerabilities. These scans are, however, actively attempting to attack the application, which may include creating or deleting data.

Fuzzing

Fuzzing is a technique of submitting lots of invalid or unexpected data to a target.

Dynamic Reviewer allows you to fuzz any request still using:

• A built-in set of Payloads. Payload Generators generate the raw attacks that the fuzzer submits to the target application

• Payload Processors are used to automatically change specific payloads before they are submitted

• Fuzz Location Processors are used to automatically change all of the payloads before they are submitted

• Custom scripts can be uploaded

HOST SCANNING

Dynamic Reviewer is integrated with the following third-party Host Scanning tools:

• Tenable Nessus (Commercial)

• Rapid7 Nexpose (Commercial)

• OpenVAS

• Nmap

The Dynamic Reviewer and thrid-party tool results will be automatically correlated for obtaining a unique results and a unified report.

PROOF-OF-EXPLOITS

Dynamic Reviewer is a DAST tool, it can detect all vulnerabilities of your site and list all possible Exploits. It won’t execute those Exploits.

If you need a full Penetration Test that includes the Exploits, you need more than one tool.

The Penetration Testing process requires an extensive set of tools. These include network (Host Scanning) and vulnerability scanning software, as well as tools that can launch specific attacks and exploits such as brute-force attacks or SQL injections, a custom reporting and a unified dashboard.

The final and most important stage of a Penetration Test is the Enterprise Report. This is a detailed report to be shared with the target company’s security team. It documents the pentesting process, vulnerabilities discovered (including the ones at client-side), proof that they are exploitable, and actionable recommendations for remediating them.

Internal teams can then use this information to improve security measures and remediate vulnerabilities. This can include patching vulnerable systems. These upgrades include rate limiting, new firewall or WAF rules, DDoS mitigation, and stricter form validation.

Dynamic Reviewer is fully integrated with Invicti Acunetix and PenTera ASV for generating proof-of-exploits and a unified Enterprise Report, multi-lingual and fully customizable for the customer’s needs, and provides a unified dashboard, based on OWASP defectDojo.

REST API

• Very simple and straightforward API.

• Easy interoperability with non-Ruby systems.

  • Operates over HTTP.

  • Uses JSON to format messages.

ENTERPRISE REPORTING

Dynamic Reviewer provides:

• Detailed Report. A standard DAST automatically-generated technical report in PDF, Word, Excel and HTML formats, listing all detailed information necessary for Indentifying and Remediate the vulnerabilities. Fully customizable ISO 9001-compliant Cover Pages, can be saved as different Profiles

You can upload two logos, and define the ISO 9001 responsability chain (Created By, Verified By, Approved By. You can add a Disclaimer Note, a ISO template code, the Confidentiality Level and a Document version.

• Enterprise Report. Fully-customized automatically-generated Executive Summary and Technical reports, starting from a customer-driven Form Template (on which customized tags will be filled), Word template, written in the preferred language (Report template in Word format, containg the custom tags).

Best Performances

Scan-times using traditional tools can range between a few hours to a couple of weeks – maybe even more. This means that wasted time can easily pile up, even when we’re talking about mere milliseconds per request/response.

Dynamic Reviewer benefits from great network performance due to its asynchronous HTTP request/response model. In this case – and from a high-level perspective –, asynchronous I/O means that you can schedule operations in such a way that they appear like they’re happening at the same time, which in turn means higher efficiency and better bandwidth utilization. That means:

• Faster hyperlink processing

• Faster numbering processing

• Faster screenshot processing

It provides a high-performance environment for the tests that need to be executed while making adding new tests very easy. Thus, you can rest assured that the scan will be as fast as possible and performance will only be limited by your or the audited server’s physical resources.

Avoiding useless technical details, the gist is the following:

• Every type of resource usage has been massively reduced — CPU, RAM, bandwidth.

• CPU intensive code has been rewritten and key parts of the system are now 2 to 55 times faster, depending on where you look.

• The scheduling of all scan operations has been completely redesigned.

• DOM operations have been massively optimized and require much less time and overall resources.

• Suspension to disk is now near instant.

  • Previously browser jobs could not be dumped to disk and had to be completed, which could cause large delays depending on the amount of queued jobs.

• Default configuration is much less aggressive, further reducing the amount of resource usage and web application stress.

Talk is cheap though, so let’s look as some numbers under Linux:

As you can see, the impact of the Performances' improvements becomes more substantial as the target’s complexity and size increases, especially when it comes to scan duration and RAM usage — and for the production site the new engine consistently yielded better coverage, which is why it performed more browser jobs.

End result:

• Runs fast on under-powered machines.

• You can run many more scans at the same time.

• You can complete scans many times faster than before.

• If you’re running scans in the “cloud”, it means that it’ll cost you many, many times less than before.

Machine Learning

The ML is what enables Dynamic Reviewer to learn from the scan it performs and incorporate that knowledge, on the fly, for the duration of the audit.

It uses various techniques to compensate for the widely heterogeneous environment of web applications. This includes a combination of widely deployed techniques (taint-analysis, fuzzing, differential analysis, timing/delay attacks) along with novel technologies (rDiff analysis, modular meta-analysis) developed specifically for the framework.

This allows the system to make highly informed decisions using a variety of different inputs; a process which diminishes false positives and even uses them to provide human-like insights into the inner workings of web applications.

Dynamic Reviewer is aware of which requests are more likely to uncover new elements or attack vectors and adapts itself accordingly.

Also, components have the ability to individually force the Core Engine to learn from the HTTP responses they are going to induce thus improving the chance of uncovering a hidden vector that would appear as a result of their probing.

DISCLAIMER: Due we make use of open source components (OWASP ZAP, w3af, pWeb, p0f, wXf, OSVDB), we do not sell the product, but we offer a yearly subscription-based Commercial Support, plus our Commercial Security Scanner.
