As you may know, I recently presented my Exchange-related talk during OffensiveCon 2024. This series of 4 blog posts is meant to supplement the talk and provide additional technical details.
In this final part, I ’am going to describe the PowerShell Remoting ConvertViaNoArgumentConstructor conversion mechanism, which I underestimated at the beginning of my research. It allowed me to find 3 more vulnerabilities, even after the Exchange PowerShell attack surface had been significantly hardened by switching to a strict allow list of types. The vulnerabilitie

CVE-2023-36025 [HIGH] Microsoft Patch Tuesday, November 2023 Edition
Microsoft today released updates to fix more than five dozen security holes in its Windows operating systems and related software, including three “zero day” vulnerabilities that Microsoft warns are already being exploited in active attacks.
The zero-day threats targeting Microsoft this month include CVE-2023-36025, a weakness that allows malicious content to bypass the Windows SmartScreen Security feature. SmartScreen is a built-in Windows component that tries to detect and block malicious websites and files. Microsoft’s security advisory for this flaw says attackers could exploit it by getting a Windows user to click on a booby-trapped link to a shortcut file.
