cvss av local

About this tag
The tag cvss av local covers the CVSS Attack Vector metric set to Local (AV:L) in vulnerability scoring, particularly in the context of Microsoft Office remote code execution (RCE) flaws. The tagged threads explain the apparent contradiction between a CVE title calling a bug "Remote Code Execution" and the CVSS vector listing AV:L. The recurring theme is that the CVE title describes the attacker's remote delivery method (e.g., emailing a malicious file), while CVSS AV:L records where the vulnerable code actually executes—on the local host when a user opens the file. This distinction is critical for Windows administrators and security teams to correctly triage, prioritize patching, and design mitigations for document-based attacks that cross the network first and detonate locally.
