Authenticated command execution via unrestricted template upload
Published Jul 12, 2025 · Updated Jul 14, 2025
Unrestricted file upload in JoeyBling SpringBoot_MyBatisPlus allows remote authenticated users to execute operating-system commands. SysFileController.upload accepts the portraitFile filename without filtering, so ../ traversal can overwrite WEB-INF/templates/error.ftl with an executable FreeMarker template at commit a6a825513bd688f717dbae3a196bc9c9622fea26. Any authenticated account can reach /file/upload; requesting a nonexistent path then renders the overwritten template and runs attacker-supplied commands.
