CVE-2024-54954Public exploitNetwork attack vector

Authenticated command execution via FreeMarker sitemap template

Published Feb 10, 2025 · Updated Feb 26, 2025

Server-side template injection in Zhyd OneBlog 2.3.6 allows remote authenticated users to execute operating-system commands via sitemap rendering. The template editor saves attacker-supplied FreeMarker directives in TM_SITEMAP_HTML, which OneBlog evaluates when /sitemap.html is rendered. Authenticated access to backend template management and a subsequent sitemap request are required; successful exploitation runs commands with the server process's privileges.
