What is CVE-2025-34070?

A missing authentication vulnerability in the GFIAgent component of GFI Kerio Control 9.4.5 allows remote attackers to perform privileged operations without authentication. The GFIAgent service exposes HTTP services on ports 7995 and 7996, leading to an authentication bypass. Through the /proxy handler on port 7996, attackers can perform arbitrary forwarding to sensitive administrative endpoints by leveraging a retrieved Appliance UUID from port 7995. This flaw provides unauthenticated access to critical administrative APIs, posing significant security risks.

Affected Version(s)

Kerio Control 9.4.5
