Does this matter?

Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.

Description

Shenzhen Tenda F3 Wireless Router firmware V12.01.01.55_multi contains a clickjacking vulnerability in the web-based administrative interface. The interface does not set the X-Frame-Options header, allowing attacker-controlled sites to embed administrative pages in an iframe and trick an authenticated administrator into unintended interactions that may result in unauthorized configuration changes.
