An authentication bypass vulnerability in the public onPhase/ frevvo registration form version 11.0.14 allows an unauthenticated remote attacker to authenticate as an arbitrary tenant user, obtain TenantAdmin and Designer privileges, and execute arbitrary operating system commands via manipulation of registration parameters containing a valid tenant name and existing user identifier.

A server-side request forgery (SSRF) issue exists in the unauthenticated form service. This allows an unauthenticated remote attacker to access sensitive internal Apache Solr data by providing a malicious URL to a publicly accessible form.

The issue is related to a security feature bypass in the Windows SmartScreen security feature, which can be exploited by a remote attacker to impact the confidentiality, integrity, and availability of protected information. This can allow attackers to affect the system.
