List of CVEs: CVE-2021-38647, CVE-2021-38648
This module is also known as OMIGOD.
By removing the authentication exchange, an attacker can issue requests to the local OMI management socket that will cause it to execute an operating system command as the root user. This vulnerability was patched in OMI version 1.6.8-1 (released September 8th 2021).
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.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.
Side Effects:
- ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
- 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.

Options
WritableDir
This is an advanced option.
A directory where you can write files. When using the Linux Dropper target, this option must be an absolute path and
less than 246 characters long.
SocketPath
This is an advanced option.
The path to the OMI server socket. The default path is /var/opt/omi/run/omiserver.sock however when this option is
left blank, it will be determined at runtime.
