Software vendor:
Siemens

The vulnerability allows a user attacker to compromise the target system.

The vulnerability exists due to use of a weak checksum algorithm to protect the configuration backup that an administrator can export from the device. A remote administrator can upload a modified configuration file to change the configuration of an affected device.

Install updates from vendor's website.
