CVE-2025-29084Public exploitNetwork attack vector

Remote code execution via unsanitized upgrade SQL

Published Sep 23, 2025 · Updated Sep 23, 2025

SQL injection in CSZ-CMS 1.3.0 allows remote attackers to create a server-side web shell through a crafted upgrade archive. The /admin/upgrade handler extracts upgrade_sql/upgrade.sql from an uploaded ZIP archive and passes its unsanitized SQL to execSqlFile, permitting an INTO OUTFILE statement to write executable PHP into the web root. The published proof of concept targets an administrative route, but the CVE assessment records no required privileges; successful code execution also requires database file-write access.
