Advisories for Golang/Github.com/Jmpsec/Osctrl package

An OS command injection vulnerability exists in the osctrl-admin environment configuration. An authenticated administrator can inject arbitrary shell commands via the hostname parameter when creating or editing environments. These commands are embedded into enrollment one-liner scripts generated using Go's text/template package (which does not perform shell escaping) and execute on every endpoint that enrolls using the compromised environment.

A stored Cross-site Scripting (XSS) vulnerability exists in the osctrl-admin on-demand query list. A user with query-level permissions can inject arbitrary JavaScript via the query parameter when running an on-demand query. The payload is stored and executes in the browser of any user (including administrators) who visits the query list page. This can be chained with CSRF token extraction to escalate privileges and take actions as the logged in user.
