|---|
| 説明 | The CicadasCMS backend template editor at /system/cms/template/save writes the request-supplied TemplateFile object (filePath and content) directly to disk: TemplateController.save() performs no validation before calling TemplateFileServiceImpl.writeTemplateFileContent(), which opens new FileOutputStream(new File(filePath)) and writes content verbatim, with no directory whitelist, no canonical-path prefix check, and no rejection of ../ or absolute paths. An authenticated backend user with template:save permission can overwrite classpath templates/configuration files, and in the Servlet-container (WAR) deployments supported by this project can write a .jsp web shell into the web application directory to achieve remote code execution. |
