The recent Microsoft Outlook zero day exposes big risks - even if patched.




The recent Microsoft Outlook Zero Day (CVE-2023-23397) issue is an interesting one on a number of fronts.

One, it is a worst case scenario zero day that can run an exploit on a person's machine to potentially gain admin credentials without any user interaction! This is the kind of vulnerability that keeps CIOs and CTOs awake at night.

Secondly, although Microsoft patched this vulnerability very quickly to stop it being exploited remotely, it is still exploitable if a malicious operator is already on your network. So as it is not completely remediated by patching alone, it requires further mitigating actions and potentially some extensive forensic follow up to determine if employees have had their accounts breached. The potential work involved could seem overwhelming.

And finally, at a high level, it is the type of issue that could force you and your company to reassess how you can better manage your security going forward.
