概要
Old CMS installations are still common in side projects, landing pages, and inherited customer sites. SPIP 3.1.2 and earlier have a template-tag handling vulnerability associated with remote code execution risk for authenticated attackers.
仕組み
The check extracts explicit SPIP version strings from `Composed-By` headers, generator meta tags, and early HTML markers. It does not upload files or attempt template execution.
被害範囲
A vulnerable SPIP installation can turn compromised editor/admin credentials into server-side code execution. Public version banners also make the target easy to triage for attackers scanning older CMS estates.

鉄壁の防御
Upgrade SPIP beyond 3.1.2, verify the deployed version directly, and remove stale public generator/version banners. Keep upload and template-management permissions restricted to trusted administrators.
