Affected devices improperly handle specific incoming BACnet MSTP messages. This could allow an attacker residing in the same BACnet network to send a specially crafted MSTP message that results in a denial of service condition of the targeted device. A power cycle is required to restore the device's normal operation.\n\ud83d\udccf Published: 2025-05-13T09:38:51.701Z\n\ud83d\udccf Modified: 2025-05-13T09:38:51.701Z\n\ud83d\udd17 References:\n1. https://cert-portal.siemens.com/productcert/html/ssa-828116.html", "creation_timestamp": "2025-05-13T10:30:36.000000Z"}, {"uuid": "b684b7fb-89d2-490b-b66c-4a91db387afb", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "CVE-2025-40556", "type": "seen", "source": "https://bsky.app/profile/cve.skyfleet.blue/post/3lp2cxirujq2p", "content": "", "creation_timestamp": "2025-05-13T10:52:40.806987Z"}, {"uuid": "575b8270-5673-46ff-8291-927f913e69d1", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "CVE-2025-40556", "type": "seen", "source": "https://www.cisa.gov/news-events/ics-advisories/icsa-25-135-03", "content": "", "creation_timestamp": "2025-05-15T10:00:00.000000Z"}]}
