What is CVE-2019-7579?

A vulnerability in Linksys WRT1900ACS routers allows an unauthenticated user to gain access to a sensitive JavaScript file on the device's webserver. This file contains crucial information that can lead to the exposure of potential passwords used to configure the default guest network. Given a list of 30 commonly used words and a random two-digit number, an attacker could exploit this weakness to conduct a brute force attack, gaining unauthorized access to the guest network and compromising security. It is essential for users of these devices to be aware of this issue and take appropriate security measures.
