CVE-2021-45841 affects TerraMaster F2-210 and F4-210 devices running TOS 4.2.X, allowing an unauthenticated attacker to craft session cookies and gain unauthorized access. This high-severity vulnerability (CVSS 8.1) has a low attack complexity and can lead to full compromise (confidentiality, integrity, availability) by leveraging a known MAC address and a user's password hash, or by exploiting the default disabled guest account with a null hash. While not currently on the CISA KEV catalog, a Metasploit module exists for unauthenticated remote code execution, indicating readily available exploit code, despite limited community discussion or media coverage.
