## What is CVE-2017-16337?

CVE-2017-16337 is a high-severity memory corruption vulnerability in Insteon Hub 2245-222, published on 23 Aug 2018. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

On Insteon Hub 2245-222 devices with firmware version 1012, specially crafted commands sent through the PubNub service can cause a stack-based buffer overflow overwriting arbitrary data. An attacker should send an authenticated HTTP request to trigger this vulnerability. At 0x9d01ef24 the value for the s_offset key is copied using strcpy to the buffer at $sp+0x2b0. This buffer is 32 bytes large, sending anything longer will cause a buffer overflow.

Weakness: CWE-120 (Buffer Copy without Checking Size of Input)

Check this codebase for CVE-2017-16337 and fix it if it is affected.

What it is: CVE-2017-16337 is a high-severity memory corruption vulnerability in Insteon Hub 2245-222, published on 23 Aug 2018. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2017-16337 in the wild and no public exploit code.

Affected product: Insteon Hub 2245-222. 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.
