Elevating Application Security with Pixee

In the digital age, where software permeates every aspect of our lives, security is a cornerstone of software development. The Audit Management System (AMS)—designed to streamline the auditing process for our company, Cooperative Bank of Oromia, audit department—stood at a crossroads: robust in functionality but vulnerable in security. This blog post chronicles our transformative journey, from a reactive security stance to a proactive, fortified future.

The integration of AppSec tools is a critical component in the development lifecycle, ensuring robust security measures are in place. This blog post offers an in-depth exploration of how these tools work in unison to enhance the security of our software. Let's dive deep!

The Pre-Pixee Era: A Vulnerable Landscape

Our AMS application, a complex system built with Spring Boot for the backend and Angular for the frontend, was developed to automate and manage audit tasks effectively. However, our security measures were rudimentary at best:

1. AMS Overview:

   • The application boasted features such as annual planning, audit scheduling, finding registration, real-time tracking, document management, and collaborative tools.

   • Given the complexity of the project, careful implementation and development are crucial. We designed the app to automate and enhance the accuracy of the auditing process. The audit team will use the application to manage all audit-related tasks efficiently. Auditing within an organization is a highly sensitive operation that can significantly impact its functioning, making robust security measures essential. We prioritize the security of our app to ensure it meets the highest standards.

   • While many applications require extensive security measures, it is particularly critical for this system due to the sensitivity of audit data. Despite its advanced capabilities, an inadequate approach to security could pose significant risks. Therefore, we'll need meticulously integrated strong security protocols to safeguard the integrity and confidentiality of the audit data.

   • Despite its advanced capabilities, the lack of a systematic approach to security posed a significant risk, especially given the sensitive nature of audit data.

2. Lack of AppSec Tools:

   • In the initial stages of developing the Audit Management System (AMS), our team’s primary focus was on delivering a suite of robust features to enhance the auditing process for the Cooperative Bank of Oromia’s audit department. This focus, however, led to an oversight in application security, as we lacked a dedicated security specialist and our developers, skilled in feature development, were not fully equipped to tackle the complex security challenges inherent in modern software.

   • Adhering to general best practices and conducting periodic code reviews were our mainstay security measures, but without specialized tools, these methods fell short of addressing the sophisticated threats that could compromise the sensitive nature of audit data. As we progressed, it became evident that integrating dedicated AppSec tools was essential to fortify our system against potential vulnerabilities, ensuring the security of the AMS aligned with its advanced capabilities.

The Turning Point: Discovering AppSec Tools

The realization that our security approach was insufficient led us to seek a solution that could offer more than just vulnerability detection. We needed a tool that could actively contribute to improving our codebase. In our search for application security (AppSec) tools, we found many useful options that could enhance the security of our app. However, most of these tools only provided suggestions, which, while valuable, were not sufficient. We wanted a tool that could do more. That’s when we discovered Pixee:

1. Pixee Integration Options:

   • Pixee offered two primary integration options: the Pixee CLI for local development scans and the Pixee GitHub App for continuous integration within our CI/CD pipeline.

   • We chose the GitHub App for its ability to automate security checks and fixes directly within our development workflow.

2. Setting Up Pixee:

   • The installation process was straightforward. After installing the Pixee GitHub App, we connected it to our repository, and it immediately began scanning our pull requests for vulnerabilities.

The AMS Security Makeover: Pixee in Action

Assessing the Current State

We began by evaluating the AMS project’s security posture:

• Security Configuration: We had basic security measures in place, such as Spring Security for authentication and authorization, but there was a clear need for more comprehensive protection. Additionally, certain configurations, like disabling CSRF protection, can unintentionally introduce vulnerabilities, leading to CSRF attacks.

• Development Practices: Our developers used tools like SonarLint for code quality checks, but these were not enough to ensure security.

Pixee’s Impact

Pixee’s introduction marked a significant shift:

• Findings Detected: As soon as Pixee was integrated into our workflow, it began its meticulous analysis of the codebase. It quickly proved its mettle by uncovering a range of security issues that had slipped past our traditional reviews. Among these were:

  • Sandboxed URL Creation Vulnerabilities: Pixeebot identified areas where our application was susceptible to sandboxed URL creation vulnerabilities. These vulnerabilities could allow attackers to exploit the URLs to perform unauthorized actions, compromising the security and integrity of our application.

  • User Uploaded File Vulnerabilities: Pixeebot also pinpointed risks associated with the handling of user-uploaded files. Without proper checks, such files could be exploited to upload malicious content or scripts, leading to severe security breaches.

• Automated Pull Requests: Pixee’s response to these findings was not just to raise alarms but to take proactive measures:

  • Proactive Fixes: For each issue detected, Pixeebot created automated pull requests with recommended fixes. These pull requests included detailed descriptions of the vulnerabilities and the proposed changes to mitigate them.
