## What is CVE-2024-8285?

CVE-2024-8285 is a medium-severity vulnerability in Red Hat Streams for Apache Kafka 2.8.0, published on 30 Aug 2024. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

A flaw was found in Kroxylicious. When establishing the connection with the upstream Kafka server using a TLS secured connection, Kroxylicious fails to properly verify the server's hostname, resulting in an insecure connection. For a successful attack to be performed, the attacker needs to perform a Man-in-the-Middle attack or compromise any external systems, such as DNS or network routing configuration. This issue is considered a high complexity attack, with additional high privileges required, as the attack would need access to the Kroxylicious configuration or a peer system. The result of a successful attack impacts both data integrity and confidentiality.

Weakness: CWE-295 (Improper Certificate Validation), CWE-297 (Improper Validation of Certificate with Host Mismatch)

Check this codebase for CVE-2024-8285 and fix it if it is affected.

What it is: CVE-2024-8285 is a medium-severity vulnerability in Red Hat Streams for Apache Kafka 2.8.0, published on 30 Aug 2024. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-8285 in the wild and no public exploit code.

Affected packages and fixed versions:
- io.kroxylicious:kroxylicious-runtime (Maven): affected all versions; fixed in 0.8.0
- io.kroxylicious:kroxylicious-runtime (Maven): affected all versions; fixed in 0.8.0

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.
