Description

This module exploits unauthenticated access to the _prep_auth_info() method in the SaltStack Salt master's ZeroMQ request server, for versions 2019.2.3 and earlier and 3000.1 and earlier, to disclose the root key used to authenticate administrative commands to the master. VMware vRealize Operations Manager versions 7.5.0 through 8.1.0, as well as Cisco Modeling Labs Corporate Edition (CML) and Cisco Virtual Internet Routing Lab Personal Edition (VIRL-PE), for versions 1.2, 1.3, 1.5, and 1.6 in certain configurations, are known to be affected by the Salt vulnerabilities. Tested against SaltStack Salt 2019.2.3 and 3000.1 on Ubuntu 18.04, as well as Vulhub's Docker image.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
