## What is CVE-2016-9335?

CVE-2016-9335 is a critical vulnerability in AutomationDirect STRIDE-Managed Ethernet Switch models, published on 9 May 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A hard-coded cryptographic key vulnerability was identified in Red Lion Controls Sixnet-Managed Industrial Switches running firmware Version 5.0.196 and Stride-Managed Ethernet Switches running firmware Version 5.0.190. Vulnerable versions of Stride-Managed Ethernet switches and Sixnet-Managed Industrial switches use hard-coded HTTP SSL/SSH keys for secure communication. Because these keys cannot be regenerated by users, all products use the same key. The attacker could disrupt communication or compromise the system. CVSS v3 base score: 10, CVSS vector string: (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). Red Lion Controls recommends updating to SLX firmware Version 5.3.174.

Weakness: CWE-798 (Use of Hard-coded Credentials), CWE-321 (Use of Hard-coded Cryptographic Key)

Check this codebase for CVE-2016-9335 and fix it if it is affected.

What it is: CVE-2016-9335 is a critical vulnerability in AutomationDirect STRIDE-Managed Ethernet Switch models, published on 9 May 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-2016-9335 in the wild and no public exploit code.

Affected product: AutomationDirect STRIDE-Managed Ethernet Switch models. 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.
