FAUCET Score

CVE-2004-0054 describes multiple vulnerabilities within the H.323 protocol implementation in Cisco IOS versions 11.3T through 12.2T. These flaws allow unauthenticated remote attackers to trigger a denial of service and potentially execute arbitrary code on affected devices. With a CVSS score of 7.5, this vulnerability is considered highly severe due to its network-based attack vector, low attack complexity, and potential for complete compromise of confidentiality, integrity, and availability.
