## What is CVE-2025-34070?

CVE-2025-34070 is a critical authentication bypass vulnerability in GFI Software Kerio Control, published on 2 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official 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.

Weakness: CWE-306 (Missing Authentication for Critical Functionality)

What it is: CVE-2025-34070 is a critical authentication bypass vulnerability in GFI Software Kerio Control, published on 2 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-34070 exists.

Affected product: GFI Software Kerio Control. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
