FAUCET Score

CVE-2001-1104 describes a critical vulnerability in SonicWALL SOHO devices, where easily predictable TCP sequence numbers allow remote attackers to spoof or hijack sessions. With a CVSS score of 7.5 (HIGH), this vulnerability is readily exploitable over the network with low attack complexity, potentially leading to unauthorized access, data compromise, and denial of service.
