Detection & IOCsextracted from sources · hover to see the quote
- →Attack vector requires a user to open a specially crafted Microsoft Word file; the Preview Pane is NOT an attack vector, so detections should focus on file-open events rather than preview events. ↗
- →Email-based delivery is a primary attack scenario — monitor for Word file attachments (e.g., .doc, .docx, .rtf) delivered via email that are subsequently opened by WINWORD.EXE. ↗
- →Web-based delivery is a secondary attack scenario — monitor for Word files downloaded from websites (including compromised sites hosting user-provided content) and opened by WINWORD.EXE. ↗
- →The exploit executes in the security context of the current user; post-exploitation actions will carry the same privileges as the logged-on user — monitor for unexpected child processes spawned by WINWORD.EXE. ↗
- ·As of the advisory publication, this vulnerability had NOT been publicly disclosed or exploited in the wild; exploitation was rated 'Less Likely' for both latest and older software releases. ↗
- ·This CVE is distinct from CVE-2020-1446 and CVE-2020-1447, which are separate Microsoft Word RCE vulnerabilities patched in the same cycle; ensure detections and patch tracking differentiate between all three. ↗

CVE-2020-1448 [HIGH] Microsoft Word Remote Code Execution Vulnerability
Microsoft Word Remote Code Execution Vulnerability
Description: A remote code execution vulnerability exists in Microsoft Word software when it fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could use a specially crafted file to perform actions in the security context of the current user. For example, the file could then take actions on behalf of the logged-on user with the same permissions as the current user.
To exploit the vulnerability, a user must open a specially crafted file with an affected version of Microsoft Word software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attac
