## Affected

- Binardat Ltd. 10G08-0800GSM Network Switch: fixed in V300SP10260209

## Description

Binardat 10G08-0800GSM network switch firmware versions prior to V300SP10260209 store a user password in a client-side cookie as a Base64-encoded value accessible via the web interface. Because Base64 is reversible and provides no confidentiality, an attacker who can access the cookie value can recover the plaintext password.

## What to do

- Check your stack: if you ship or depend on Binardat Ltd. 10G08-0800GSM Network Switch, upgrade to a fixed version (V300SP10260209) per the references below.
