Unauthenticated dangerous-file upload via JimuReport endpoint
Published Jun 16, 2023 · Updated Dec 17, 2024
Unrestricted file upload in JeecgBoot 3.5.0 allows remote attackers to store dangerous files through the JimuReport upload endpoint. The /jeecg-boot/jmreport/upload controller filters only ../ sequences before constructing a local file and does not restrict dangerous file types. Unauthenticated network access is sufficient; an uploaded HTML file executes stored script when visited, while uploaded shell files are stored without demonstrated server-side execution.
