Vendor: Weidmüller

Description

The vulnerability allows a remote attacker to gain access to other users' credentials.

The vulnerability exists due to application stored credentials in plain text in a configuration file on the system. A remote attacker with access to the device can view contents of the configuration file and gain access to passwords for 3rd party integration.

Mitigation
Install updates from vendor's website.
