46
FAUCET Score

CVE-2007-5351 is an unspecified vulnerability within the Server Message Block Version 2 (SMBv2) signing support in Microsoft Windows Vista. This flaw allows remote attackers to force signature re-computation and execute arbitrary code by sending a specially crafted SMBv2 packet. With a CVSS score of 10.0, it represents a critical risk due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite its high severity and EPSS score, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
