CVE-2020-35229 — Netgear Gs116E Firmware security vulnerability

High CVSS 8.8

The authentication token required to execute NSDP write requests on NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices is not properly invalidated and can be reused until a new token is generated, which allows attackers (with access to network traffic) to effectively gain administrative privileges.

Matched remediation archetype

General vulnerability remediation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
