CVE-2001-0203

CVE-2001-0203 describes a critical vulnerability in the Watchguard Firebox II firewall, where read-only users can escalate privileges to read-write access and administrative control. This is achieved by accessing a file containing hashed passphrases and leveraging these hashes for authentication. With a CVSS score of 10.0, this vulnerability is highly severe, allowing unauthenticated attackers to achieve complete compromise (confidentiality, integrity, and availability) over the network via a low-complexity attack. Despite its age and severity, there is no evidence of active exploitation, publicly available exploit code in common databases like Metasploit or ExploitDB, or significant community discussion or media coverage.
