# Rejetto HTTP File Server, up to and including version 2.3m, is vulnerable to a template injection vulnerability

Rejetto HTTP File Server has a template injection flaw that lets a remote attacker send one crafted HTTP request to run commands on the host. No login is needed, and CISA lists it as actively exploited in the wild with ransomware use noted.

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

## Affected

- vendor:Rejetto HTTP File Server affected ? fixed ?
- vendor:rejetto http file server affected <= 2.4 fixed ?

## How to check

Find any running Rejetto HTTP File Server (hfs.exe) instances on your network and check their version against the vendor advisory; the sources do not give a command.

## Fix

Remove or stop the Rejetto HTTP File Server or replace it, since CISA says to discontinue use if mitigations are unavailable; the sources do not name a fixed version.

## From the sources

Rejetto HTTP File Server contains an improper neutralization of special elements used in a template engine vulnerability. This allows a remote, unauthenticated attacker to execute commands on the affected system by sending a specially crafted HTTP request.

CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
