vulnerability analysis and mitigation

CVE-2025-47953 is a critical remote code execution vulnerability affecting Microsoft Office, discovered and disclosed on June 10, 2025, as part of Microsoft's June 2025 Patch Tuesday security updates. The vulnerability is classified as a use-after-free vulnerability that allows an unauthorized attacker to execute code locally (Wiz, NVD).

The vulnerability has been assigned a CVSS vector of CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating local access, low attack complexity, no privileges required, and high impacts on confidentiality, integrity, and availability. The vulnerability received a CVSSv3.1 base score of 8.4 (HIGH). The Preview Pane has been identified as an attack vector for exploitation. The vulnerability stems from improper restriction of file names and resources in Microsoft Office (NVD, Wiz).

If successfully exploited, this vulnerability allows an attacker to execute arbitrary code on the affected system with the privileges of the current user. The vulnerability's high CVSS score of 8.4 reflects its severe potential impact on system security, particularly concerning as it can be triggered through the Preview Pane without user interaction (Wiz).

Microsoft has released a security patch as part of their June 2025 Patch Tuesday updates to address this vulnerability. Organizations are strongly advised to apply the security updates immediately, particularly given the critical nature of the vulnerability and its potential for exploitation through the Preview Pane (Microsoft Support).
