# Veeam Agent for Linux: local privilege escalation to root on managed hosts

Veeam Agent for Linux has a flaw that lets a local user escalate their privileges. Only installations managed by a Veeam Backup & Replication instance are affected, according to the NVD description.

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

## How to check

- Check the installed Veeam Agent for Linux version on each Linux host with `veeamconfig --version` (command assumed from Veeam product usage; sources do not confirm it)
- Check whether the agent is managed by a Veeam Backup & Replication server (sources do not say how to verify this)

## Fix

- Upgrade Veeam Agent for Linux to the fixed release named in the Veeam advisory (version unknown from the sources)
- Review local accounts with shell access on managed Linux hosts until patched
