CVE-2020-14519
This vulnerability allows an attacker to use the internal WebSockets API for CodeMeter (All versions prior to 7.00 are affected, including Version 7.0 or newer with the affected WebSockets API still enabled. This is especially relevant for systems or devices where a web browser is used to access a web server) via a specifically crafted Java Script payload, which may allow alteration or creation of license files for when combined with CVE-2020-14515.

Use the current Version 7.10 of the Software CodeMeter Runtime, available via the manufacturer's website. https://www.wibu.com/de/support/anwendersoftware/anwendersoftware.html Only use the Software CodeMeter Runtime as Client. The software tools named under affected products use the Software CodeMeter Runtime as Client in their default setting. Pilz also recommends using a local firewall to limit unwanted access to the network ser- vices of the device with Software CodeMeter Runtime installed.
