CVE-2025-62554: CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') in Microsoft Microsoft 365 Apps for Enterprise
Access of resource using incompatible type ('type confusion') in Microsoft Office allows an unauthorized attacker to execute code locally.
AI Analysis
Technical Summary
This vulnerability in Microsoft 365 Apps for Enterprise (version 16.0.1) is caused by type confusion, where the software accesses a resource using an incompatible type. This flaw enables an unauthorized attacker to execute arbitrary code locally without user interaction or privileges. The CVSS 3.1 vector indicates local attack vector, low attack complexity, no privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability. The vulnerability is officially published and a patch is available from Microsoft.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary code locally on the affected system, potentially leading to full compromise of confidentiality, integrity, and availability of the system running Microsoft 365 Apps for Enterprise version 16.0.1. There is no indication of remote exploitation or requirement for user interaction, increasing the risk if an attacker has local access.
Mitigation Recommendations
A patch is available for this vulnerability. It is recommended to apply the official Microsoft update for Microsoft 365 Apps for Enterprise version 16.0.1 as soon as possible to remediate this issue. No additional mitigations are specified or required beyond applying the patch.
