What it is: CVE-2014-3223 is a high-severity denial of service vulnerability in S9300,S2300,S3300,S5300,S6300 S9300 with software V100R006C00SPC500??S9300 with software V100R006C00SPC800,S2300,S3300,S5300,S6300 with software V100R006C00SPC800,V100R006C01SPC100, V100R006C03, published on 2 Apr 2017. 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-2014-3223 in the wild and no public exploit code.

Affected product: S9300,S2300,S3300,S5300,S6300 S9300 with software V100R006C00SPC500??S9300 with software V100R006C00SPC800,S2300,S3300,S5300,S6300 with software V100R006C00SPC800,V100R006C01SPC100, V100R006C03. 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.
