Citrix ShareFile is an enterprise-level file sharing solution for businesses using which employees can securely exchange proprietary and sensitive business data with each other. If exploited, the vulnerabilities could allow an unauthenticated attacker to compromise the storage zones controller potentially and access sensitive ShareFile documents and folders. If your storage zone was created on any of the affected versions, merely upgrading your software to a patched version would not completely resolve the vulnerability. The company has separately released a mitigation tool that you need to be run on your primary Storage zones controller first and then on any secondary controllers.
