Log4j is an open-source Java logging library developed by the Apache Foundation. It is widely used in many applications and is present in many services as a dependency.
Gold-Vision CRM is not run within an Apache environment as such it is not affected by the above exploit. We do not run any Apache/Java services within our own hosted/production environment.
Our own hosted environment is within the Microsoft Domain and access/installation is controlled to keep the production environment sterile.
We regularly patch our severs in line with best practice, also we are pro-active in our malware and antivirus processes.
If you host your own Gold-Vision CRM software then we would recommend that you check your own environment.
To be clear, Gold-Vision CRM is NOT affected by the Log4J Vulnerability.
