## What is CVE-2019-5017?

CVE-2019-5017 is a medium-severity vulnerability in Netgear R8000 Firmware, published on 17 Jun 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

An exploitable information disclosure vulnerability exists in the KCodes NetUSB.ko kernel module that enables the ReadySHARE Printer functionality of at least two NETGEAR Nighthawk Routers and potentially several other vendors/products. An unauthenticated, remote attacker can craft and send a packet containing an opcode that will trigger the kernel module to return several addresses. One of which can be used to calculate the dynamic base address of the module for further exploitation.

Weakness: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)

Check this codebase for CVE-2019-5017 and fix it if it is affected.

What it is: CVE-2019-5017 is a medium-severity vulnerability in Netgear R8000 Firmware, published on 17 Jun 2019. 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-2019-5017 in the wild and no public exploit code.

Affected product: Netgear R8000 Firmware. 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.
