Beware of New Microsoft Visio Remote Code Execution Vulnerability

CVSScvssV3_1: 7.8

Microsoft Visio is a popular diagramming and vector graphics application used for flowcharts, UML diagrams, floor plans and more. Unfortunately, researchers have discovered a remote code execution vulnerability in Visio that could allow hackers to take control of users’ computers remotely without their knowledge.

The vulnerability, tracked as CVE-2023-21737, is a remote code execution flaw that resides in how Visio handles specially crafted files. By tricking a user into opening a malicious file, hackers could exploit this flaw to execute arbitrary code on the targeted system with the same privileges as the user. This would give the attacker full control of the infected computer and allow them to install malware, view and steal data or use it to launch attacks on other machines on the network.

The vulnerability is considered highly critical as it does not require any user interaction beyond opening a file. Hackers could disguise malicious files as legitimate blueprints or diagrams to trick users.

To stay protected, users should ensure they have the latest security updates installed for Visio. Microsoft has released a patch to address this issue so make sure automatic updates are enabled. Users should also be cautious of any files received from untrusted or unknown sources and avoid opening them unless absolutely necessary. Following basic cyber safety practices like using strong and unique passwords can also help reduce risks.

Stay vigilant and keep your software updated to avoid falling victim to this or other remote code execution vulnerabilities in the future.
