Microsoft Reports Vulnerabilities Impacting Windows and Office Products
Microsoft is investigating reports of a series of remote code execution vulnerabilities impacting Windows and Office products.
Microsoft reads, “An attacker could create a specially crafted Microsoft Office document that enables them to perform remote code execution in the context of the victim. However, an attacker would have to convince the victim to open the malicious file.“
Microsoft has confirmed no less than 132 security vulnerabilities across product lines, including six that fall into the “zero-day” category.
Microsoft suggested these applications would be impacted and is aware of targeted attacks that attempt to exploit these vulnerabilities by using specially crafted Microsoft Office documents.
Office Products include:
– Excel – Publisher – PowerPoint – Word – WordPad – Access – Graph – Visio
An attacker could create a specially crafted Microsoft Office document that enables them to perform remote code execution in the context of the victim. However, an attacker would have to convince the victim to open the malicious file.
SoHo Network Solutions has always encouraged its customers not to open email attachments they do not recognize or expect. Free antivirus solutions are better than nothing, however, they lack centralized management and advanced features that we can provide. Hackers have become more advanced, so more advanced solutions are needed. The good news is that paid professional-grade antivirus software has become more affordable than ever. For $4 a month per computer, you can get the protection needed to help combat these vulnerabilities.
The Technical Details:
The vulnerability is a remote code execution (RCE) vulnerability affecting Windows and Office product, CVE-2023-36884, with a CVSS score of 8.3. The targeted attacks exploit these vulnerabilities using specially crafted Microsoft Office documents.” CVE-2023-36884 is as yet unpatched.
If you have any questions or concerns about this, please don’t hesitate to call Soho Network Solutions at 717.831.8128. It is recommended you ensure you have all Windows and Office updates and a strong antivirus program.

How does EDR work?
Endpoint detection and response are broadly defined by three types of behavior.
This refers to EDR’s ability to be deployed on an endpoint, record endpoint data, then store that data in a separate location for analysis now or in the future. EDR can be deployed as a standalone program or included as part of a comprehensive endpoint security solution. The latter has the added benefit of combining multiple capabilities into a single endpoint agent and offering a single pane of glass through which admins can manage the endpoint.
EDR technology can interpret raw telemetry from endpoints and produce endpoint metadata (or cyber threat intelligence) human users can use to determine how a previous attack went down, how future attacks might go down, and actions that can be taken to prevent those attacks.
EDR scans for programs, processes, and files matching known parameters for malware. Threat hunting also includes the ability to search all open network connections for potential unauthorized access.
Incident response refers to EDR’s ability to capture images of an endpoint at various times and re-image or rollback to a previous good state in the event of an attack. EDR also gives administrators the option to isolate endpoints and prevent further spread across the network. Remediation and rollback can be automated, manual, or a combination of the two.
Think of EDR as a flight data recorder for your endpoints. During a flight, the so-called “black box” records dozens of data points; e.g., altitude, air speed, and fuel consumption. In the aftermath of a plane crash, investigators use the data from the black box to determine what factors may have contributed to the plane crash … Likewise, endpoint telemetry taken during and after a cyberattack (e.g. processes running, programs installed, and network connections) can be used to prevent similar attacks.
