Introduction This is the second Technical Advisory post in a series wherein I audit the security of popular Remote Monitoring and Management (RMM) tools. (First: Multiple Vulnerabilities in Faronics Insight). I was joined in this security research by Colin Brum, Principal Security Consultant at NCC Group. In this post I describe the 16 vulnerabilities which […]

Summary The com.proxyman.NSProxy.HelperTool application (version 1.4.0), a privileged helper tool distributed with the Proxyman application (up to an including versions 4.10.1) for macOS 13 Ventura and earlier allows a local attacker to use earlier versions of the Proxyman application to maliciously change the System Proxy settings and redirect traffic to an attacker-controlled computer, facilitating MITM […]

[…]

Description The NSIS uninstaller package did not enforce appropriate permissions on the temporary directory used during the uninstall process. Furthermore, it did not ensure that the temporary directory was removed before running executable content from it. This could potentially result in privilege escalation under certain scenarios. Impact A low-privileged, local attacker could exploit this vulnerability […]

Overview This article explains how to write a custom ROP (Return Oriented Programming) chain to bypass Data Execution Prevention (DEP) on a Windows 10 system. DEP makes certain parts of memory (e.g., the stack) used by an application non-executable. This means that overwriting EIP with a “JMP ESP” (or similar) instruction and then freely executing […]
