The German Federal Office for Information Security has declared IT Threat Level 4/Red for the CVE-2021-44228 ("log4shell") vulnerability in the widely used Java software library log4j.
estos products are not affected by this vulnerability and can continue to be used without modification and without hesitation.
estos software is not based on Java and is therefore generally not affected by Java-related vulnerabilities. The only exception is ProCall for Android, here Java is partly used, but not log4j (neither version 1 nor 2).
Apache log4net(https://logging.apache.org/log4net/)not to be confused with Apache web server, Apache Tomcat or other Apache projects) is a different technology. There was security advice for this, for which we have provided new software versions.
