Code Auditing Guidelines: Detecting and Fixing unsafe YAML loading allowing remote code execution in Your Ruby Monolith

Understanding the YAML Deserialization Vulnerability Many Ruby applications, especially older monoliths, rely on YAML for configuration, data storage, and inter-process communication. The `YAML.load` method in Ruby, when used with untrusted input, presents a significant security risk. This is because YAML is a superset of JSON and can represent arbitrary Ruby objects. When `YAML.load` encounters a […]

Securing Your E-commerce APIs: Preventing admin route brute force and session hijacking vulnerabilities in Magento 2 Implementations

Attackers exploit XSS vulnerabilities to inject malicious scripts into web pages viewed by other users, leading to session hijacking, credential […]

How We Audited a High-Traffic Perl Enterprise Stack on Google Cloud and Mitigated Remote Code Execution (RCE) via eval block syntax flaws

Initial Reconnaissance and Attack Surface Identification Our engagement began with a deep dive into the existing infrastructure. The core of the application was a Perl monolith, handling millions of requests daily, hosted on Google Cloud Platform (GCP). The primary attack vectors we focused on were user-supplied input points that could potentially reach dangerous Perl constructs, […]

How We Audited a High-Traffic C++ Enterprise Stack on Linode and Mitigated XML External Entity (XXE) injection in old SOAP integrations

Initial Threat Landscape Assessment: SOAP, XXE, and Legacy C++ Our engagement began with a critical security audit of a high-traffic enterprise stack hosted on Linode. The core of the concern revolved around legacy SOAP integrations, a common vector for XML External Entity (XXE) injection vulnerabilities. These integrations, built on a C++ foundation, processed sensitive client […]

Preparing for PCI-DSS Compliance: Security Hardening in WooCommerce and OVH Infrastructures
