- →CVE-2018-8423 is triggered when a user opens or imports a specially crafted Microsoft JET Database Engine file; monitor for suspicious JET/MDB file opens, especially via email attachments or Office documents. ↗
- →The vulnerability requires a user to open or import a specially crafted JET Database Engine file; in email attack scenarios, the attacker sends the crafted file and convinces the user to open it — flag inbound email attachments with JET/MDB/ACCDB extensions. ↗
- ·Exploit status is publicly disclosed but not confirmed exploited in the wild at time of advisory; exploitation assessed as 'Less Likely' for both latest and older software releases. ↗
- ·The October 2018 patch may be incomplete; customers should restrict interaction with vulnerable applications to trusted files until full remediation is confirmed. ↗

CVE-2018-8423 [HIGH] Patch Tuesday, October 2018 Edition
Microsoft this week released software updates to fix roughly 50 security problems with various versions of its Windows operating system and related software, including one flaw that is already being exploited and another for which exploit code is publicly available.
Another vulnerability patched on Tuesday — CVE-2018-8423 — was publicly disclosed last month along with sample exploit code.
