Microsoft Internet Explorer 6 and 7 does not properly determine the domain or security zone of origin of web script, which allows remote attackers to bypass the intended cross-domain security policy and obtain sensitive information via a crafted HTML document, aka "Cross-Domain Information Disclosure Vulnerability."

Analyst readout for executives and security teams

Plain-English summary

CVE-2008-3474 is an information disclosure flaw in Microsoft Internet Explorer 6 and 7. A malicious HTML document could cause the browser to misjudge where script content came from, letting an attacker bypass cross-domain protections and read sensitive information if a user opens the content.

Executive priority

Treat as a legacy-risk cleanup item unless IE6 or IE7 remains in use. If those browsers still support business-critical workflows, prioritize patch verification, browser retirement planning, and network restrictions because confidentiality impact is high.

Technical view

The issue is a same-origin or security-zone origin determination failure in IE6 and IE7 script handling. The CVSS vector indicates network attackability, low complexity, no privileges, required user interaction, unchanged scope, and high confidentiality impact only.

Likely exposure

Exposure is mainly legacy environments still running Internet Explorer 6 or 7, including old workstations, kiosks, embedded systems, or application compatibility islands. Modern supported browsers are not identified as affected in the provided bundle.

Exploitation context

The bundle does not cite active exploitation, and KEV status is false. Exploitation requires user interaction with crafted HTML content. The main risk is confidential data leakage across domains or security zones, not code execution or service disruption.

Researcher notes

The provided affected-product metadata is incomplete, but the CVE description identifies IE6 and IE7. No CWE is supplied. Research should focus on origin/security-zone boundary behavior, patch applicability, and whether legacy compatibility systems still expose users to crafted HTML.

Mitigation direction

  • Apply Microsoft MS08-058 or the referenced KB956390 update where applicable.
  • Retire Internet Explorer 6 and 7 wherever business applications allow.
  • Restrict legacy IE systems from untrusted web and email content.
  • Check current Microsoft or vendor guidance for unsupported legacy dependencies.

Validation and detection

  • Inventory endpoints and applications that still launch IE6 or IE7.
  • Verify MS08-058 or KB956390 patch status through vulnerability management records.
  • Use the referenced OVAL definition where your scanner supports it.
  • Confirm legacy browsers cannot reach untrusted internet content.
