These flaws are rated as having a high likelihood of exploitation and,crucially,require no user interaction to trigger.This means an⁢ attacker could⁢ exploit these‌ vulnerabilities simply by sending ‍a specially crafted file, ⁤potentially‌ through the Preview ‍Pane in Outlook or⁤ other ‍Office‍ applications. additional Office​ vulnerabilities⁤ addressed include ⁢ CVE-2025-49697 and CVE-2025-49702.

Hopkins explains ​that successful‍ exploitation allows attackers to execute arbitrary SQL queries with elevated privileges within ConfigMgr. This could lead to:

Malicious software deployment ‍across your entire network.
