CVE-2010-3330: Microsoft Internet Explorer 6 through 8 does not properly restrict script access to content from a differen...

Security readout for executives and security teams

This flaw let a malicious website read sensitive content that Internet Explorer 6 through 8 should have kept separated by domain or security zone. The main business risk is data leakage from legacy browser sessions, especially where old IE is used for intranet or line-of-business applications. Exposure is most likely in legacy environments still using Internet Explorer 6, 7, or 8. The bundle also cites an Avaya confirmation reference, but does not provide product or version details. Modern environments without these browsers should have limited direct exposure. Treat this as a legacy-risk cleanup item unless old Internet Explorer remains in operational use. If IE 6 through 8 is still used for intranet workflows, prioritize remediation because the flaw can expose sensitive data across trust boundaries. Mitigation focus: Review and apply Microsoft MS10-071 guidance for affected Internet Explorer systems.; Inventory remaining Internet Explorer 6, 7, and 8 usage across endpoints and legacy applications.; Decommission unsupported browser dependencies where business processes still require old Internet Explorer..
