FAUCET Score

CVE-2002-0150 describes a buffer overflow vulnerability in Microsoft Internet Information Server (IIS) versions 4.0, 5.0, and 5.1. This flaw allows remote attackers to bypass HTTP header safety checks, potentially leading to a denial of service or arbitrary code execution. With a CVSS score of 7.5 (HIGH) and an EPSS score indicating a higher-than-average exploitability, this vulnerability presents a significant risk due to its low attack complexity and potential for complete compromise of confidentiality, integrity, and availability. Despite its high risk, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
