Securing Your E-commerce APIs: Preventing Remote Code Execution (RCE) via insecure file uploads in Magento 2 Implementations

Understanding the RCE Vector in Magento 2 File Uploads Remote Code Execution (RCE) via insecure file uploads is a persistent threat, particularly in complex e-commerce platforms like Magento 2. Attackers exploit vulnerabilities in how the system handles user-submitted files, often by uploading malicious scripts disguised as legitimate assets. In Magento 2, this can manifest in […]

An Auditor’s Checklist for Securing PHP Backends on Linode

PHP Version and Extension Management A fundamental aspect of securing any PHP backend is ensuring you’re running a supported and actively patched version. Outdated PHP versions are a significant attack vector due to known, unpatched vulnerabilities. Similarly, unnecessary or insecure extensions must be disabled or removed. On a Linode server, you can check your current […]

How We Audited a High-Traffic WordPress Enterprise Stack on Linode and Mitigated Remote Code Execution (RCE) via insecure file uploads

Initial Triage: Identifying the Attack Vector Our engagement began with a critical alert: a high-traffic WordPress enterprise deployment on Linode was exhibiting anomalous behavior, suggestive of a potential compromise. The initial indicators pointed towards unauthorized file system access and unusual outbound network traffic. The primary goal was to rapidly identify the entry point and contain […]

How We Audited a High-Traffic WooCommerce Enterprise Stack on AWS and Mitigated Race conditions during high-concurrency payment processing

Deep Dive: Auditing a High-Traffic WooCommerce Stack on AWS This post details a recent security and performance audit of a large-scale WooCommerce enterprise deployment hosted on AWS. The primary objective was to identify and mitigate critical race conditions within the payment processing pipeline, particularly under high-concurrency loads. We’ll walk through the diagnostic process, tooling, and […]

Code Auditing Guidelines: Detecting and Fixing Buffer overflow vulnerability in high-performance network sockets in Your C Monolith

Understanding Buffer Overflows in C Network Sockets Buffer overflows remain a persistent threat, particularly in high-performance C network applications. These vulnerabilities arise when a program writes data beyond the allocated buffer’s boundaries, potentially overwriting adjacent memory. In the context of network sockets, this often involves unsanitized input received from external sources, which attackers can exploit […]

Code Auditing Guidelines: Detecting and Fixing XML External Entity (XXE) injection in old SOAP integrations in Your C Monolith

Understanding the XXE Threat in Legacy SOAP Integrations Many established C-based monolithic applications still rely on SOAP for inter-service communication. While SOAP itself is a robust protocol, its XML payload is susceptible to XML External Entity (XXE) injection attacks, especially when parsed by older, unhardened XML parsers. An attacker can exploit XXE vulnerabilities to read […]

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

Initial Triage: Identifying the Attack Surface Our engagement began with a critical security audit of a high-traffic enterprise stack hosted on OVH. The primary concern was a potential vulnerability in legacy SOAP integrations, a common vector for XML External Entity (XXE) injection. The stack comprised several microservices, a central API gateway, and a complex data […]

How We Audited a High-Traffic Magento 2 Enterprise Stack on Linode and Mitigated Remote Code Execution (RCE) via insecure file uploads

Initial Reconnaissance and Vulnerability Discovery Our engagement began with a deep dive into the existing infrastructure and application layer of a high-traffic Magento 2 Enterprise e-commerce platform hosted on Linode. The primary objective was to identify potential attack vectors, with a specific focus on Remote Code Execution (RCE) vulnerabilities, often stemming from insecure file upload […]

How We Audited a High-Traffic C++ Enterprise Stack on DigitalOcean and Mitigated insecure memory deallocation leading to information disclosure

Initial Assessment and Threat Landscape Our engagement began with a high-level threat model for a critical C++ enterprise application deployed on DigitalOcean. The application handled sensitive customer data and processed a significant volume of transactions daily. The primary concern was a potential information disclosure vulnerability stemming from insecure memory management practices within the C++ codebase. […]

How We Audited a High-Traffic Shopify Enterprise Stack on Linode and Mitigated Broken Object Level Authorization (BOLA) in API gateway endpoints

Understanding the Threat: Broken Object Level Authorization (BOLA) In a high-traffic Shopify Enterprise stack, particularly one leveraging a custom API gateway for enhanced control and extensibility, the risk of Broken Object Level Authorization (BOLA) is significant. BOLA occurs when an application fails to properly enforce authorization checks on individual objects, allowing an authenticated user to […]
