CVE-2019-19394 - Mission Portal JavaScript injection vulnerability

April 16, 2020

A vulnerability was recently discovered in CFEngine Mission Portal and has now been fixed. Under certain circumstances, it was possible to inject JavaScript code into data presented in Mission Portal, that would be run in the user’s browser. This security issue was fixed in CFEngine 3.10.7, 3.12.3, and 3.15.0, and will be mitigated by upgrading your hub to one of these versions (or later). No other action is required than upgrading the Hub. This issue is present in CFEngine Enterprise 3.7 versions, 3.10.0 through 3.10.6, as well as 3.12.0, 3.12.1, and 3.12.2. All customers have been notified prior to this announcement and had time to address the issue. Any community users who use CFEngine Enterprise Free 25 should upgrade immediately. Open source versions of CFEngine (CFEngine Community) are not affected, as they do not include the Mission Portal Web UI. The security of the CFEngine product and our users is something we take very seriously, and we will continue to look for, fix and responsibly disclose serious weaknesses in our product(s). This issue has been registered as CVE-2019-19394 in the official public CVE registry. If you have any questions or concerns please contact CFEngine support if you have a support contract or email
