High (8.7) in asus router firmware. EPSS 1.2% estimated probability of exploitation activity in the next 30 days.

On this page
Improper neutralization of special elements used in an OS command in certain ASUS Router firmware allows an unauthenticated nearby user to trigger a chain of actions—unauthenticated queries, identifier guessing, credential overwriting, and command injection—resulting in the execution of arbitrary commands with root privileges. Refer to the ' Security Update for ASUS Router Firmware ' section on the ASUS Security Advisory for more information.
