CVE-2005-4827

23
FAUCET Score

CVE-2005-4827 describes a vulnerability in Internet Explorer 6.0 (and potentially other versions) that allows remote attackers to bypass the same-origin policy. This is achieved by manipulating the XMLHttpRequest object's method name with special characters, which some proxy servers interpret as spaces, enabling requests outside the intended domain. The vulnerability has a CVSS score of 7.5 (High), indicating a network-based attack with low complexity and potential for partial compromise of confidentiality, integrity, and availability. While it can lead to referer spoofing and HTTP Request Smuggling, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
