Loading vulnerability…
CVE-2020-1015 is an elevation of privilege vulnerability in the Windows User-Mode Power Service (UMPS). The vulnerability exists due to improper handling of objects in memory by UMPS, which could allow a local attacker to execute arbitrary code with elevated privileges. This vulnerability is distinct from other similar privilege escalation issues patched in the same cycle.

This repository is a proof-of-concept (PoC) exploit for CVE-2020-1015, a vulnerability in the Windows Power service (umpo.dll) that can be triggered via a local RPC interface. The repository contains three files: a README with build instructions, an IDL file (Source.idl) defining the vulnerable RPC interface, and a C++ source file (cve_2020_1015.cpp) implementing the exploit logic. The exploit works by creating two threads that repeatedly call the UmpoRpcLegacyEventRegisterNotification RPC function with crafted parameters, causing the Power service to crash. The exploit demonstrates a denial of service condition but does not provide privilege escalation or remote code execution. The main attack vector is local, requiring the attacker to execute code on the target system. The exploit targets the 'umpo' RPC endpoint, the Power service's interface (UUID 6c9b7b96-45a8-4cca-9eb3-e21ccf8b5a89), and the umpo.dll binary. The code is a functional PoC and requires compilation with Visual Studio on Windows.
