CVE-2020-11628

An issue was discovered in EJBCA before 6.15.2.6 and 7.x before 7.3.1.2. It is intended to support restriction of available remote protocols (CMP, ACME, REST, etc.) through the system configuration. These restrictions can be bypassed by modifying the URI string from a client. (EJBCA's internal access control restrictions are still in place, and each respective protocol must be configured to allow for enrollment.)
