What is CVE-2021-42887?

The TOTOLINK EX1200T router contains a vulnerability that allows an attacker to bypass authentication completely. By sending a specially crafted request to the router's formLoginAuth.htm endpoint, an unauthorized user can gain access without providing valid login credentials. This poses a significant risk to network integrity and security, as it could allow attackers to manipulate the device settings, intercept data, or perform further attacks on the local network.
