MyReport is a report generation software often used as a component of web-based applications. We describe a privilege escalation and remote code execution vulnerabilities in MyReport Updater 2.1.1 through its update configuration and gRPC service.

Local privilege escalation in the Cato VPN Client through the split-tunnel upload flow, from named pipe to SYSTEM delete and Windows Installer rollback.

The edge isn't the AI model, but how you assemble the system around it. We built a custom agentic harness that structures vulnerability research into distinct stages, from codebase exploration and analysis to validation and exploitation. Applied to FreeRDP, the workflow found vulnerabilities that could be chained into remote code execution, with a human researcher validating the findings and guiding the process along the way.

Chamilo is an open source Learning Management System (LMS) widely deployed in schools and enterprises around the world. In this blogpost we explain how we were able to identify multiple vulnerabilities including a full unauthenticated Remote Code Execution chain in the latest version.

An Optical Line Terminal (OLT) is the central device in a Fiber-To-The-Home (FTTH) network that connects and manages all customer connections, making it a critical control point in an ISP's infrastructure for delivering high speed Internet. This article uncovers how unauthenticated access to OLTs can lead to a full network takeover starting by exploiting exposed vulnerable devices, showing how to pivot into the cloud-based fleet manager using other vulnerabilities, and then compromising an ISP's entire infrastructure.

Exploitation of an arbitrary directory deletion via symlink following in the antivirus Intego.

This blog post dives into the most common classes of macOS Local Privilege Escalation vulnerabilities, from insecure XPC communications and time-of-check to time-of-use (TOCTOU) Race Conditions to a range of implementation and configuration oversights. We will explore how attackers can exploit these weaknesses to escalate privileges, and highlight real-world examples to illustrate recurring patterns. This post ends the series on Intego products on macOS by revealing vulnerabilities that can lead to Local Privilege Escalation, as well as a surprise bonus.

PageJack is a Linux kernel exploitation technique useful to generate a Use After Free (UAF) in the page allocator. In this article we provide a detailed example of how to use it to exploit a Linux kernel vulnerability from 2022.

Three vulnerabilities in Avira Internet Security, from an arbitrary file delete primitive to two distinct paths to SYSTEM privileges.
