PHOENIX CONTACT: TC Router and TC Cloud Client multiple vulnerabilities

Impact
CVE-2017-16544
This Vulnerability could potentially result in code execution, arbitrary file writes, or other attacks.
The impact of this vulnerability on the device is limited because shell access is only possible with administrator privileges.

CVE-2020-9436
An attacker can abuse this vulnerability to compromise the operating system of the device by injecting system commands.

CVE-2020-9435
These attacks could allow an attacker to gain access to sensitive information like admin credentials, configuration parameters or status information and use them in further attacks.

Mitigation
The pre-installed generic X.509 certificate should be renewed or replaced by an individual certificate during initial configuration. For details on replacing this certificate please refer to the user manual on page 51 et seq. Press 'renew' to create a new self-signed device certificate or upload a user specific certificate with the upload dialog.

To avoid the manual generation of an individual certificate, the devices will be shipped with individual certificates starting with a future release.

Remediation
Phoenix Contact strongly recommended to update affected devices to newest Firmware version
