SIMATIC Cloud Connect 7 vulnerabilities

A vulnerability has been identified in SIMATIC Cloud Connect 7 CC712 (All versions >= V2.0 < V2.1) and CC716 (All versions >= V2.0 < V2.1). The filename in the upload feature of the web based management of the affected device is susceptible to a path traversal vulnerability. This could allow an authenticated privileged remote attacker to write any file with the extension `.db`.

In SIMATIC Cloud Connect 7 CC712 (versions >= V2.0 < V2.1) and CC716 (versions >= V2.0 < V2.1), the export endpoint discloses some undocumented files. This could allow an unauthenticated remote attacker to gain access to additional information resources.

The export endpoint in SIMATIC Cloud Connect 7 is accessible via REST API without authentication. This could allow an unauthenticated remote attacker to download files available via the endpoint.

SIMATIC Cloud Connect 7 devices (CC712 and CC716) in versions prior to V2.1 are vulnerable to a denial of service when parsing a random non-JSON MQTT payload. An attacker able to manipulate communication between the MQTT broker and the device can cause a denial of service.

A vulnerability in SIMATIC Cloud Connect 7 CC712 (versions >= V2.0 < V2.1) and CC716 (versions >= V2.0 < V2.1) involves a path traversal flaw in the upload feature of the web-based management. An authenticated privileged remote attacker could overwrite or download any file the Linux user 'ccuser' has write or read-only access to, respectively.
