FAUCET Score

CVE-2009-1544 is a double free vulnerability in the Workstation service of Microsoft Windows, affecting Windows XP, Server 2003, Vista, and Server 2008. This flaw allows remote authenticated attackers to gain privileges on older systems (XP/Server 2003) or cause a denial of service on newer ones (Vista/Server 2008) via a crafted RPC message. With a CVSS score of 8.8 (HIGH), it represents a significant risk due to its network-based attack vector, low attack complexity, and high potential for impact on confidentiality, integrity, and availability. Despite its high severity and FAUCET Risk Score of 96/100, there is no evidence of active exploitation, no known public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage.
