CVE-2023-21715 is a security flaw that affects Microsoft Publisher, a popular software application used for creating and editing various types of documents. Specifically, this vulnerability allows attackers to bypass a critical security feature within Microsoft Publisher known as Office macro policies. These policies are designed to block untrusted or malicious files from being executed.
Exploiting CVE-2023-21715 requires a user with authentication to the targeted system to carry out the attack locally. An authenticated attacker could leverage social engineering techniques to convince a victim to download and open a specially crafted file from a website. Once the malicious file is executed, it could lead to a local attack on the victim's computer.
Although the vulnerability requires elevated privileges and user interaction, it is essential to take CVE-2023-21715 seriously due to its potential impact. While Microsoft has classified it as an Important vulnerability, any flaw that allows attackers to misuse macros in an Office document without triggering a block should be addressed promptly. It is crucial for users to install the patch provided by Microsoft as soon as possible.
If you have automatic updates enabled, the patch should be installed automatically. If not, you can manually check for updates by going to Settings > Update & Security > Windows Update.
