server side parsing
About this tag
Discussions tagged with server side parsing on WindowsForum.com focus on security vulnerabilities where remote code execution is achieved through server-side processing of malicious files. A key example is CVE-2025-62556, a Microsoft Excel Remote Code Execution flaw that involves server-side parsing of crafted Excel documents. The tag covers how such vulnerabilities are analyzed, including the apparent contradiction between a local attack vector in the CVSS score and the remote delivery method. Topics include the role of server-side parsing in triggering exploits, the distinction between remote delivery and local execution, and implications for enterprise security. The tag is relevant for IT professionals and security researchers examining server-side parsing risks in Microsoft Office and similar environments.
