Web App Testing - Understanding Risks with Vector Command

What Happened

Web applications have become essential for organizations, serving as gateways to critical data and services. However, they also present significant security risks. A staggering 75% of successful breaches reported by Vector Command were executed through web applications. As attackers increasingly target these platforms, understanding their vulnerabilities is crucial for maintaining security.

Vector Command, a continuous managed red team service by Rapid7, focuses on evaluating web applications from an attacker's perspective. Instead of just scanning for bugs, it identifies exploitation paths that could lead to meaningful compromises, such as account takeovers and session hijacking. This approach allows organizations to see beyond theoretical vulnerabilities and understand real-world risks.

How Vector Command Approaches Web Applications

Vector Command's methodology revolves around a fundamental question: Can this application compromise the organization? Testing begins without authentication, exploring what potential attackers can see. If vulnerabilities exist—like misconfigurations or broken authentication—Vector Command pursues these paths as part of a broader attack chain.

The goal is not to provide a long list of low-risk findings but to deliver a clear picture of what truly works in an attack scenario. This targeted approach helps organizations prioritize their security efforts effectively.

A Real-World Example: Ticketing System Attack

A recent engagement illustrated how attackers can exploit seemingly innocuous systems. By targeting a popular SaaS ticketing portal, attackers used social engineering to gain access to internal workflows. They submitted a ticket to the IT team, cleverly embedding a phishing link that captured login sessions and MFA prompts.

This incident highlights how attackers can exploit trust relationships within applications. The breach was not due to a single critical vulnerability but rather the interaction between systems that had not been adequately validated. Vector Command aims to uncover such risks, ensuring organizations understand the potential consequences of their application ecosystems.

Vector Command and Web App Pentesting: Better Together

While Vector Command and traditional web application penetration testing serve different purposes, they complement each other effectively. Penetration testing focuses on improving code security, while Vector Command assesses how applications impact overall security exposure.

Together, they provide a comprehensive view of an organization's security posture. By continuously testing assumptions, Vector Command helps organizations stay ahead of potential threats, ensuring that their applications do not become gateways for attackers.
