## Overview

Insufficient encryption strength in Sprecher Automation SPRECON-E-C, SPRECON-E-P, and SPRECON-E-T3 allows a local unprivileged attacker to extract data from update images and thus obtain limited information about the architecture and internal processes.

## Affected

- `sprecon-e-c_firmware < 9.0`
- `sprecon-e-p_firmware < 9.0`
- `sprecon-e-t3_firmware < 9.0`

## Remediation

Upgrade past the affected range:

- `sprecon-e-c_firmware 9.0`
- `sprecon-e-p_firmware 9.0`
- `sprecon-e-t3_firmware 9.0`
