During an assumed breach ops via a virtual desktop interface, we discovered a wildcard allow firewall rule for the Azure Blob Storage service. We proved that even with restrictions in place, it was still possible to reach the Internet. Afterwards, we thought of abusing this firewall misconfiguration (recommended by Microsoft) in a much more useful way. To demonstrate that I built a SOCKS5 proxy that uses blobs to tunnel traffic to the target's internal network.

The following article explains how, during an audit, we examined Moodle (v4.4.3) and found ways of bypassing all the restrictions preventing SSRF vulnerabilities from being exploited.

A technical exploration of a trivial Local Privilege Escalation Vulnerability in CCleaner <= v1.18.30 on macOS.

The following article describes how, during an "assumed breach" security audit, we compromised multiple web applications on our client's network in order to carry out a watering hole attack by installing fake Single Sign-On pages on the compromised servers. This article is the first of a two-part series and explains why it is not enough to just check for CVEs, and why we should dive deep into the code to look for new vulnerabilities in old code bases. We will take phpMyAdmin version 2.11.5 as an example, as this is the version we encountered during the audit.

In this series of articles we describe how, during an "assumed breach" security audit, we compromised multiple web applications on our client's network to carry out a watering hole attack by installing fake Single Sign-On pages on compromised servers. In our second episode we take a look at SOPlanning, a project management application that we encountered during the audit.

The following article explains how during an audit we took a look at Apache Superset and found bypasses (by reading the PostgreSQL documentation) for the security measures implemented.

The following article explains how during a Purple Team engagement we were able to identify a vulnerability in Microsoft Teams on macOS allowing us to access a user's camera and microphone.

The following blogpost explains how during a Red Team engagement we were able to identify several vulnerabilities including Remote Code Executions in the latest version of Chamilo.

Discovery of two vulnerabilities (CVE-2024-34065) in Strapi, an open source content management system. In this post we explain how these vulnerabilities, if chained together, allow authentication to be bypassed.

The following article explains how during a Red Team engagement we were able to develop a 1day for GLPI CVE-2023-43813 which later led to the identification of an arbitrary object instantiation leading to an SSRF referenced as CVE-2024-27098 as well as an SQL injection referenced as CVE-2024-27096.
