Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
A vulnerability has been identified in SIMATIC Cloud Connect 7 CC712 (All versions >= V2.0 < V2.1), SIMATIC Cloud Connect 7 CC712 (All versions < V2.1), SIMATIC Cloud Connect 7 CC716 (All versions >= V2.0 < V2.1), SIMATIC Cloud Connect 7 CC716 (All versions < V2.1). The affected device is vulnerable to a denial of service while parsing a random (non-JSON) MQTT payload. This could allow an attacker who can manipulate the communication between the MQTT broker and the affected device to cause a denial of service (DoS).
