Hazard

Is CVE-2017-5521 being exploited?

Weaponised and widely attempted

Reliable public exploit code exists, or mass exploitation attempts are probable. Patch inside days, not weeks.

NETGEAR Multiple Devices Exposure of Sensitive Information Vulnerability

NETGEAR · Multiple Devices

CVSS 8.1 EPSS 89% 1 public exploit Fix deadline passed 29 September 2022

What it is

Multiple NETGEAR devices are prone to admin password disclosure via simple crafted requests to the web management server.

Why we say that

  • EPSS puts exploitation in the next 30 days at 89%
  • 1 public exploit published
  • CISA's federal remediation deadline (2022-09-29) has passed
  • Listed in the CISA Known Exploited Vulnerabilities catalogue

Every line above comes from a named public source. Where the evidence is thin, we say so rather than inventing confidence — see methodology.

What to do

Apply updates per vendor instructions. If the affected device has since entered end-of-life, it should be disconnected if still in use.

Public exploit code

Indexed from Exploit-DB. Presence of code raises urgency; absence does not mean safety.

What it costs when this goes wrong

This is where UK enforcement meets the vulnerability record. Where an unfixed vulnerability leads to a breach, the ICO treats it as a security failure under UK GDPR. Recent cases:
