Web Application Penetration Testing

What is Web Application Penetration Testing?

WEB application penetration test, also known as a pen test, is a simulated cyber attack against your web app to check for exploitable vulnerabilities or find vulnerabilities in business logic of application.

Web Application Security is essential for all commercial website owners who believe traffic to their page for business purposes. It’s a selected sort of Information Security that protects a comprehensive range of web platforms from security breaches

zerOxImpact leads the industry in web application penetration testing, identifying vulnerabilities during a variety of programming languages and environments. From web apps in highly scalable AWS environments to legacy apps in traditional infrastructure, out security experts have helped secure data across the globe.

Many people depend upon web apps to handle their most sensitive information, whether it’s for financial planning or medical aid. With their growing complexity comes unforeseen security flaws. This risk increases as web applications become more interconnected through the linking of APIs. Security researchers find new methods of creating these applications bend and break a day.

The best defense is a good offense. By hiring a expirienced team of penetration testers to assess your applications, you’ll be made conscious of every security hole that would cause compromised applications and data breaches. This provides you with the foresight needed to fortify your web application and keep your most sensitive assets where they need.

What is Our Approach for Web Pentest?

Penetration testing goes under a structured methodology.

We prioritize this idea in each engagement to form sure that our assessment is reliable, reproducible to be valuable for you. As such, our findings can always be verified by your team before and after the remediation. to urge these results, we are guided by the subsequent steps:

Define the Scope of


Before a Web application assessment happens, zerOxImpact defines a transparent scope for the client.

  • Determine which of the organization’s applications should be tested
  • Make exclusions from the assessment known (specific pages/subdomains)
  • Decide on the official testing period and emergency contacts

zerOxImpact penetration testing engineers collect the maximum amount of information as they will on the target, employing of OSINT (Open Source Intelligence) tools and techniques. The gathered data will help us to know the operating conditions of the organization, which allows us to assess risk accurately because the engagement progresses. Targeted intelligence may include:

  • PDF, DOCX and other files leaked by Google dorks
  • Previous breaches and open credential leaks
  • Explore robots.txt file

During enumeration stage, we incorporate automated scripts and tools, among other tactics, in additional advanced operation. Engineers carefully examine any possible attack vectors. The gathered information from this stage is going to be the idea for our exploitation within the next phase.

  • Enumerating directories/subdomains
  • Checking cloud services for possible misconfigurations
  • Correlating known vulnerabilities with the appliance and relevant services

Secops stage

Attack and

Penetration Testing

With careful consideration, we start to attack vulnerabilities found within the webapp. This is often done cautiously to guard the appliance and its data, while still verifying the existence of discovered attack vectors. At offincive stage, we may perform attacks such as:

  • SQL injection and/or XXE injection
  • Try breached credentials and brute force tools against login pages
  • Monitoring web app functionality for insecure protocols

Reporting is that the end of security assessment engagement. We do analysis and aggregate all obtained information and supply the client comprehensive details and proofs of findings.

The report begins with a high-level breakdown of the general risk, highlighting both strengths and weaknesses within the application’s protective systems and logic.

We also include recommendations to assist business leaders in making informed decisions regarding the appliance.

Into the report, we break down each vulnerability during a technical manner, including our testing process, reproduce and remediation steps making for an easy remediation process. Further, we include a filled security checklist with information that we check to know testing coverage better.

We attend great lengths to make sure each report is both explicit and straightforward to navigate.

Upon client request, we may review an assessment after the client organization has patched vulnerabilities. We’ll make sure the risk has been eliminated, and now new bugs appear. The previous assessment report is going to be updated to reflect the safer state of the appliance.

Frequently Asked Questions.
Here are some common questions about Web Application Penetration Testing.

Web Services

zerOxImpact offers web service testing, manipulating, and fuzzing parameters WSLD for example. Such web services have many unique components and risks, they will also contain many similar vulnerabilities as typical applications, like SQL Injection.

As a part of an internet application security assessment, our team will analyze the following key areas within your applications:

  • Architecture
  • Business Logic, Functional Specification & Implementation
  • Authentication
  • Access Control & Authorization
  • Cryptography
  • Session Management
  • Data Validation
  • Error Condition Handling & Exception Management
  • Data Confidentiality
  • Management Interface
  • Privacy Concerns
