spaceraccoon/cve-2020-10665POC for CVE-2020-10665 Docker Desktop Local Privilege Escalation
POC for Docker Desktop Local Privilege Escalation. Built based on the writeup at https://www.activecyber.us/activelabs/docker-desktop-local-privilege-escalation-cve-2020-10665.
Hardlink creation adapted from https://github.com/googleprojectzero/symboliclink-testing-tools.
This exploit grants full control permissions for the Everyone group to C:\\Windows\\System32\\DriverStore\\FileRepository\\prnms003.inf_amd64_a337db27fa50b915\\Amd64\\PrintConfig.dll. To affect other files, simply change the line LPCWSTR dllPath = L"C:\\Windows\\System32\\DriverStore\\FileRepository\\prnms003.inf_amd64_a337db27fa50b915\\Amd64\\PrintConfig.dll"; in CVE-2020-10665/CVE-2020-10665.cpp.
By overwriting PrintConfig.dll, attackers can escalate arbitrary file overwrite to SYSTEM access based on the steps at https://decoder.cloud/2019/11/13/from-arbitrary-file-overwrite-to-system/. You will need to modify the xps.ps1 script in that writeup to point to the matching PrintConfig.dll path on the target system as well as generate your own reverse shell payload DLL.
Due to the hardlink mitigation introduced in the March 2020 Windows cumulative update, this exploit only works on prior versions of Windows.
