Microsoft says remote unauthenticated attackers can trivially exploit a critical Outlook security vulnerability that also lets them bypass the Office Protected View.
Unauthenticated attackers can exploit CVE-2024-21413 remotely in low-complexity attacks that don't require user interaction.
"An attacker who successfully exploited this vulnerability could gain high privileges, which include read, write, and delete functionality," Microsoft explains.
Microsoft updated the CVE-2024-21413 security advisory today to warn that this Outlook bug was also being exploited in attacks as a zero-day before this month's Patch Tuesday.
Citrix warns of new Netscaler zero-days exploited in attacks.
