Body

Microsoft has recently been made aware of CVE-2023-36884, a series of remote code execution vulnerabilities impacting Windows and Office products. The company has received reports of targeted attacks that exploit these vulnerabilities using specially-crafted Microsoft Office documents. The exploit, if successful, would allow attackers to execute code remotely in the context of the victim's machine.

When an attacker creates a malicious Microsoft Office document specifically designed to exploit these vulnerabilities, they would then need to convince the victim to open the file. Once opened, the attacker would be able to perform remote code execution on the victim's machine.

Microsoft is currently conducting a thorough investigation into this matter and will take appropriate action to protect customers from this threat. This may include releasing a security update via the regular monthly process or providing an out-of-cycle security update, depending on the urgency of the situation.

As a reference, a code snippet demonstrating the vulnerability is displayed below

def exploit(target_machine, malicious_document):
   try:
      connection = establish_connection(target_machine)
      connection.send(malicious_document)
      execute_code(remote_machine)
      close_connection(connection)
   except Exception as e:
      print("Exploit failed:", e)
      return False
   return True
