CVE-2019-14526

Severity: high (CVSS 8.1 v3.0)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.7% probability of exploitation in the next 30 days
Public exploit or detection template: yes
Published: 2019-08-14 · updated 2026-06-17
Weakness: CWE-352

Description

An issue was discovered on NETGEAR Nighthawk M1 (MR1100) devices before 12.06.03. The web-interface Cross-Site Request Forgery token is stored in a dynamically generated JavaScript file, and therefore can be embedded in third party pages, and re-used against the Nighthawk web interface. This entirely bypasses the intended security benefits of the use of a CSRF-protection token.

Affected products

NETGEAR Mr1100 Firmware: before 12.06.03 — fixed in 12.06.03

How to fix

Upgrade to a fixed version: NETGEAR Mr1100 Firmware 12.06.03. Check the vendor advisory for mitigations.
