CVE-2025-60703
📋 TL;DR
This vulnerability allows an authorized attacker to exploit an untrusted pointer dereference in Windows Remote Desktop to elevate privileges locally. It affects systems running vulnerable versions of Windows with Remote Desktop enabled. Attackers must already have some level of access to the system to exploit this flaw.

⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker gains SYSTEM-level privileges, enabling complete system compromise, data theft, lateral movement, and persistence establishment.
Likely Case
An authenticated user with standard privileges elevates to administrative rights, allowing installation of malware, configuration changes, and access to sensitive data.
If Mitigated
With proper access controls and network segmentation, impact is limited to the compromised host with reduced lateral movement potential.
🎯 Exploit Status
Requires authenticated access. Exploitation involves manipulating pointer dereferences in RDP components.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Microsoft Security Update Guide for specific KB numbers
