## What is CVE-2024-7595?

CVE-2024-7595 is a medium-severity authentication bypass vulnerability in IETF RFC2784 - Generic Routing Encapsulation (GRE), published on 5 Feb 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

GRE and GRE6 Protocols (RFC2784) do not validate or verify the source of a network packet allowing an attacker to spoof and route arbitrary traffic via an exposed network interface that can lead to spoofing, access control bypass, and other unexpected network behaviors.

This can be considered similar to CVE-2020-10136.

## Which versions are affected by CVE-2024-7595?

It affects 2 products.


Products: Ietf Generic Routing Encapsulation, Ietf Generic Routing Encapsulation6.

## How do I fix CVE-2024-7595?

No fix has been published for CVE-2024-7595 yet. Limit exposure of the affected software until one is available.

## Is CVE-2024-7595 being exploited?

There is no known exploitation of CVE-2024-7595 in the wild and no public exploit code.

Public exploit code:

Check this codebase for CVE-2024-7595 and fix it if it is affected.

What it is: CVE-2024-7595 is a medium-severity authentication bypass vulnerability in IETF RFC2784 - Generic Routing Encapsulation (GRE), published on 5 Feb 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-7595 in the wild and no public exploit code.

Affected product: IETF RFC2784 - Generic Routing Encapsulation (GRE). 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.
