## Overview

Hirschmann HiLCOS Classic Platform switches Classic L2E, L2P, L3E, L3P versions prior to 09.0.06 and Classic L2B prior to 05.3.07 contain a credential exposure vulnerability where user passwords are synchronized with SNMPv1/v2 community strings and transmitted in plaintext when the feature is enabled. Attackers with local network access can sniff SNMP traffic or extract configuration data to recover plaintext credentials and gain unauthorized administrative access to the switches.

## Remediation
