# SSH administration service lets any domain user run server code

Link for people: https://infrastack.ai/live/CVE-2026-111239 (this .md is for agents)

An optional SSH administration service gives every user who logs in through its configured login domain full access to the administration shell, without checking for an admin role. An attacker with any such user's credentials, including a low-privileged application user, can run arbitrary code as the server process.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether the SSH administration service is enabled on the server; the sources do not name the product or its settings, so this needs the vendor's documentation.
- Check which login domain the service is configured to accept, and whether it includes non-administrative users.
- Check whether the service's port is reachable from untrusted networks.

## From the sources

The optional SSH administration service grants full access to the administration shell to every user that authenticates against its configured login domain, without checking for an administrative role. An attacker holding the credentials of any user in that domain, including a low-privileged application user, can execute arbitrary code as the server process. Users are recommended to disable the SSH administration service, or to block network access to it from untrusted clients and restrict its login domain to administrative users.
