Lifecycle Timeline
2DescriptionCVE.org
An insufficient input validation vulnerability in the listed NETGEAR RAX series models allows a network-adjacent attacker having network access (such as WiFi credentials) to crash the router's management UI. There is no confidentiality or integrity impact. A crash of the router's management UI does not impact the availability of the router's core services like WiFi network.
AnalysisAI
Stack-based buffer overflow in the NETGEAR RAX series router management UI (RAX30, RAX35, RAX38, RAX40, RAXE300) enables an adjacent-network attacker holding valid WiFi credentials to crash the web management interface. The vendor explicitly bounds the impact to management UI unavailability - core router services including the WiFi network and routing plane continue operating normally with no confidentiality or integrity exposure. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must possess valid WiFi credentials (the description explicitly cites WiFi credentials as the access mechanism) and must be positioned on the adjacent network segment - the CVSS AV:A metric confirms network adjacency is required, ruling out remote internet-based exploitation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.5 rating with vector AV:A/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L accurately captures the tightly bounded real-world risk: the attacker must be on the same network segment and hold valid WiFi credentials, and the sole consequence is a temporary crash of the management web UI that does not disrupt routing or wireless service. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update firmware to the patched thresholds identified in EUVD-2026-73164: RAX38 to V1.0.6.106 or later, RAX30 to V1.0.9.92 or later, RAXE300 to V1.0.10.72 or later, RAX40 to V1.0.6.106 or later, and RAX35 to V1.0.10.72 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
