CVE-2023-28311

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Microsoft Office Word. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of DOCX files. Crafted data in a DOCX file can trigger a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.

Microsoft Word appears to suffer from a remote code execution vulnerability when a user load a malicious file that reaches out to an attacker-controller server to get a hostile payload.
