Cross-domain vulnerability in Microsoft XML Core Services 3.0 through 6.0, as used in Microsoft Expression Web, Office, Internet Explorer, and other products, allows remote attackers to obtain sensitive information from another domain and corrupt the session state via HTTP request header fields, as demonstrated by the Transfer-Encoding field, aka "MSXML Header Request Vulnerability."

Security readout for executives and security teams

This older Microsoft XML Core Services flaw could let a remote attacker bypass normal same-domain boundaries and access sensitive information associated with another domain. It also could corrupt session state through crafted HTTP request header fields. The source bundle does not show active exploitation or a CVSS score. Exposure is most likely in legacy Microsoft environments where MSXML 3.0 through 6.0 remains installed or reachable through Internet Explorer, Office, Expression Web, or dependent applications. Medium priority unless legacy Microsoft client software remains in sensitive workflows. The issue is old and not KEV-listed in the bundle, but cross-domain data exposure can matter where unsupported systems persist. Mitigation focus: Review Microsoft MS08-069 guidance for affected software and available updates.; Inventory systems and applications using MSXML 3.0 through 6.0.; Prioritize remediation on legacy endpoints handling sensitive browser or Office workflows..
