CVE-2003-0815: Internet Explorer 6 SP1 and earlier allows remote attackers to bypass zone restrictions and read arbitrary...

Security readout for executives and security teams

This is a legacy Internet Explorer flaw that could let a malicious webpage bypass browser security zones and read local files. The business risk is mostly in forgotten legacy systems, kiosks, lab machines, or embedded workflows still using Internet Explorer 6 SP1 or earlier. Exposure is likely limited to legacy environments that still retain Internet Explorer 6 SP1 or earlier, especially systems allowed to browse untrusted content or render attacker-controlled HTML. Prioritize discovery over broad emergency response. If affected browsers are still in production, treat remediation as urgent because remote web content could expose local files. Mitigation focus: Identify and remove Internet Explorer 6 SP1 or earlier where present.; Apply Microsoft MS03-048 guidance on any retained affected systems.; Block untrusted web browsing from legacy systems until remediated..
