Web App Penetration testing can help identify flaws and vulnerabilities before the bad guys exploit them.

According to Positive Technologies’ latest Web Application Vulnerabilities and Threats Report, 82% of web application vulnerabilities lie in the source code. The report also noted that nine times out of 10, hackers could attack site visitors. Other highlights included:

  • Sixteen percent of web apps contained vulnerabilities that allowed attackers to take full control of the system.
  • Eight percent of the systems had full control of the web application server that allowed an attack on the local network.
Web-based technologies bring many advantages to the table and can connect seamlessly with customers, supply chains, and other stakeholders. Web apps have become an asset for most organizations that interact and conduct business online. Unfortunately, attackers may be analyzing your business applications for vulnerabilities before any security risks become known.

Overview

CYBRI Web App penetration testing moves beyond the constraints of automated scanning. Our Red Team conducts manual testing to pinpoint any business logic vulnerabilities and also assesses the security of the code used by the application.

Internal web app security testing is not as effective as third-party testing — because web apps are critical systems in any network, you need a fresh set of eyes. It’s not a myth that application developers are generally experts in their domain and code, but they are rarely cybersecurity experts.

The CYBRI Red Team provides a fresh set of eyes that can discover weaknesses in your applications, spot coding mistakes, locate software bugs, ensure effective implementation of app controls, and analyze actual risk.

Web App Security

Web app security covers the security encompassing websites, web applications, and web services. The most common web application attack vectors include code injection, broken authentication, and sensitive data exposure.

The Top 10 OWASP vulnerabilities in 2020

  • Injection
  • Broken Authentication
  • Sensitive Data Exposure
  • XML External Entities (XXE)
  • Broken Access control
  • Security misconfigurations
  • Cross-Site Scripting (XSS)
  • Insecure Deserialization
  • Using Components with known vulnerabilities
  • Insufficient logging and monitoring

Injection

Code injection or Remote Code Execution (RCE) occurs when an attacker submits invalid data to a web app to introduce and execute malicious code.

Broken Authentication

Broken authentication is when the authentication mechanism is insecure or does not work properly. Often this is found when passwords are submitted in cleartext or using a weak cipher suite.

Sensitive Data Exposure

Data exposure occurs usually in two ways: unexpected user actions reveal data that was not protected by authentication or when view permissions are overly permissive and allow accounts to access data they shouldn't be able to.

XML External Entities (XXE)

XXE is when XML references are allowed but not properly implemented, which allows the attacker to use a reference that can be used to exploit the application.

Broken Access control

Broken Access control is the ability for a user to access resources beyond what they were intended to. This often happens when developers do not check access levels on every action, so unexpected behavior bypasses protection, such as direct URL requests or unhiding hidden fields.

Security misconfigurations

A security misconfiguration is when controls are in place but not properly set up for the needs of the application.

Cross-Site Scripting (XSS)

XSS is a type of injection that causes the application to run a script. This can be done client-side, server-side and stored and non-stored. The most dangerous is a stored server-side XSS, where an attacker has permanently saved a script to run on the application.

Insecure Deserialization

Insecure deserialization is when an attacker can modify data in transit between application components and it allows for unauthenticated changes. This often leads to RCE.

Using Components with known vulnerabilities

Vulnerabilities are all given a CVE number. Ensure that any component used in the application does not have a CVE in the version. This affects libraries, applications, plug-ins and more.

Insufficient logging and monitoring

Logging is important as it can alert to attacker behaviors that will allow for quicker detection and response time, as well as being able to learn how to prevent future attacks.

Depending upon the type of infrastructure you have, the methods attackers use are continually changing, as attacks evolve.

Methodologies & Scope

Over time, web applications have become more sophisticated in structure and code and thus provide a larger attack surface. Understanding how attackers target these applications is critical in defending them. It is also crucial to understand which areas to test to receive meaningful results.

Web App Testing Phases

Phase one determines the scope, type of test and how it will be performed. Phase two tests your web app defenses and phase three provides you with a highly detailed report:

1- Planning Phase

— Information Gathering

  • Define the scope
  • Collect information - integration points, web architecture, web services integration
  • Determine success criteria - define and approved by the client
  • Review previous testing (if any)
  • Review infrastructure and testing environment

2 - Testing Phase

— Test Your Defenses (attacks & execution)

  • Interface and functionality testing
  • API Endpoint Testing and Fuzzing
  • Input Field Attacks and Injections
  • User Privilege Escalation
  • Unitentend Action Manual Testing
  • Business Logic Testing

3 - Reporting Phase

  • Details on vulnerabilities found, the methodology used, and locations where the problems exist.

Throughout the testing phase, clients have access to all discoveries and can ask questions at any time. After the completion of the testing, there is a question and answer session to help internal teams understand and mitigate all discovered vulnerabilities.

The CYBRI Cybersecurity Lifecycle does not stop there. We provide continual support for vulnerability management and remediation, re-testing, and vCISO and Secure SDLC services to provide your application with a full spectrum cybersecurity solution.

Web App Pen Testing Features and Benefits

Penetration testing helps find the vulnerabilities attackers may exploit before the bad guys do.

Penetration testing could have prevented the Equifax data breach and the Panama Papers breach. Both organizations suffered major hacks due to web application vulnerabilities. A chain is only as strong as its weakest link — one small flaw in your web app, website, or web service can break security.

Features of our pen testing services include:

  • On-demand testing
  • Team collaboration
  • Data-rich dashboards
  • Clean reports
  • Historical data analysis
  • Remediation tracking

Benefits of our pen testing services:

  • Uncover vulnerabilities in web apps
  • Test the effectiveness of your defenses
  • Spot mistakes made by developers
  • Discover bugs in existing software
