CVE-2010-0555

32
FAUCET Score

CVE-2010-0555 is a critical vulnerability affecting Microsoft Internet Explorer versions 5.01 SP4 through 8, as well as several Windows operating systems. This flaw, known as the URLMON sniffing vulnerability, allows remote attackers to bypass security restrictions and read arbitrary local files by tricking IE into rendering non-HTML files as HTML documents, particularly after a redirection. With a CVSS score of 9.3 and a FAUCET Risk Score of 96/100, the vulnerability presents a severe risk due to its network-based attack vector, medium complexity, and complete compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code, or significant community discussion has been observed, its high severity warrants immediate patching.
