# CVE-2025-34501: Shuffle Master Deck Mate 2 Hard-coded Credentials & Exposed Services

- Severity: CVSS 7.0 (High), CNA
- Vector: CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: all known versions prior to 2025-10-23
- Published: 2025-11-03 · Updated: 2026-07-28

## Affected

- Light & Wonder, Inc. / SHFL Entertainment, Inc. / Shuffle Master, Inc. Deck Mate 2: fixed in all known versions prior to 2025-10-23

## Description

Deck Mate 2 is distributed with static, hard-coded credentials for the root shell and web user interface, while multiple management services (SSH, HTTP, Telnet, SMB, X11) are enabled by default. If an attacker can reach these interfaces - most often through local or near-local access such as connecting to the USB or Ethernet ports beneath the table - the built-in credentials permit administrative login and full control of the system. Once authenticated, an attacker can access firmware utilities, modify controller software, and establish persistent compromise. Remote attack paths via network, cellular, or telemetry links may exist in specific configurations but generally require additional capabilities or operator error. The vendor reports that USB access has been disabled in current firmware builds.

## What to do

- Check your stack: if you ship or depend on Light & Wonder, Inc. / SHFL Entertainment, Inc. / Shuffle Master, Inc. Deck Mate 2, upgrade to a fixed version (all known versions prior to 2025-10-23) per the references below.
