A technical exploration of Local Privilege Escalation Vulnerability in ControlPlane on macOS.
During a Red Team engagement, we compromised an AWS account containing a Confluence instance hosted on an EC2 virtual machine. Although we fully compromised the machine hosting the Confluence instance, we did not have valid credentials to log in but were able to interact with the underlying database. This led us to study the structure of the Confluence database and the mechanism for generating API tokens.
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.
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 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.
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.
