## What is CVE-2018-11629?

CVE-2018-11629 is a critical vulnerability in n/a, published on 2 Jun 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Default and unremovable support credentials (user:lutron password:integration) allow attackers to gain total super user control of an IoT device through a TELNET session to products using the HomeWorks QS Lutron integration protocol Revision M to Revision Y. NOTE: The vendor disputes this id as not being a vulnerability because what can be done through the ports revolve around controlling lighting, not code execution. A certain set of commands are listed, which bear some similarity to code, but they are not arbitrary and do not allow admin-level control of a machine

Weakness: CWE-798 (Use of Hard-coded Credentials)

Check this codebase for CVE-2018-11629 and fix it if it is affected.

What it is: CVE-2018-11629 is a critical vulnerability in n/a, published on 2 Jun 2018. 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-2018-11629 in the wild and no public exploit code.

Affected product: n/a. 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.
