About this tag
The vulnerability scoring tag on WindowsForum.com covers discussions about how Microsoft and CVSS classify vulnerabilities, particularly the apparent mismatch between advisory titles like "Remote Code Execution" and CVSS Attack Vector values such as Local (AV:L). Threads explain that the advisory describes the attacker's origin and impact, while CVSS scoring describes the technical exploit path, such as local file processing. Topics include CVE examples in Word, Excel, and PowerPoint, and how to interpret CVSS fields for accurate risk assessment. The tag is useful for IT professionals and security analysts navigating vulnerability scoring nuances in Microsoft products.
