AI-analyzed exploit summary This repository contains a functional Proof-of-Concept (PoC) for CVE-2025-30406, a ViewState deserialization vulnerability in ASP.NET applications. The exploit uses ysoserial to generate a malicious payload and includes a custom HTTP server for exfiltrating command output.

Description

Gladinet CentreStack through 16.1.10296.56315 (fixed in 16.4.10315.56368) has a deserialization vulnerability due to the CentreStack portal's hardcoded machineKey use, as exploited in the wild in March 2025. This enables threat actors (who know the machineKey) to serialize a payload for server-side deserialization to achieve remote code execution. NOTE: a CentreStack admin can manually delete the machineKey defined in portal\web.config.
