ACROS Security 0patch (0PatchServicex64.exe) Unquoted Service Path Privilege Escalation


Vendor: ACROS, d.o.o.
Product web page: https://www.0patch.com
Affected version: 2016.05.19.539

Summary: 0patch (pronounced 'zero patch') is a platform for instantly
distributing, applying and removing microscopic binary patches to/from
running processes without having to restart these processes (much less
reboot the entire computer).

Desc: The application suffers from an unquoted search path issue impacting
the service '0patchservice' for Windows deployed as part of 0patch solution.
This could potentially allow an authorized but non-privileged local user to
execute arbitrary code with elevated privileges on the system. A successful
attempt would require the local user to be able to insert their code in the
system root path undetected by the OS or other security applications where
it could potentially be executed during application startup or reboot. If
successful, the local userâs code would execute with the elevated privileges
of the application.

Tested on: Microsoft Windows 7 Ultimate SP1 (EN)
Microsoft Windows 7 Professional SP1 (EN)
