remote delivery local execution

About this tag
The tag remote delivery local execution clarifies a common confusion in Microsoft security advisories, particularly for vulnerabilities like CVE-2025-59224 and CVE-2025-59233 in Excel. While these bugs are labeled as Remote Code Execution (RCE), their CVSS vectors list Attack Vector as Local (AV:L). This apparent contradiction arises because the advisory's 'Remote' refers to the attacker's ability to deliver a crafted file from a remote location (e.g., via email or shared link), whereas the CVSS AV:L describes where the exploit actually executes—on the victim's machine after the user opens the file. Understanding this distinction is essential for accurate triage, prioritized patching, and designing mitigations in enterprise environments.
