Technical Analysis
CVE-2023-36884 is a fixed vulnerability that permitted remote code execution. Attackers could manipulate Microsoft Office files to bypass the Mark of the Web (MoTW) security mechanism. This bypass allowed these documents to be accessed without a security prompt, facilitating remote code execution. In response to the once-mitigated but still exploited CVE-2023-36884 weakness, Microsoft rolled out an Office Defense in Depth patch as part of August 2023 Patch Tuesday.
The Russian cyber group, Storm-0978/RomCom, has been actively exploiting this flaw.
