Short explanation
FineReport 9.0 allows unauthenticated attackers to write arbitrary files via the design_save_svg operation of /WebReport/ReportServer by injecting directory‑traversal sequences in the filePath parameter. An attacker can upload a JSP webshell and achieve remote code execution (CVE‑2021‑48014).
File write capability enables attackers to gain full control of the server and potentially exfiltrate sensitive data.
What should be done?
- Follow the vendor advisory for FineReport 9.0
- Monitor for unexpected file uploads in the ReportServer directory
- Validate or restrict the filePath parameter
- Deploy a web‑application firewall to block traversal payloads
- Update the application when a fix becomes available

Show the technical text from the sources
FineReport 9.0 contains a path traversal vulnerability in the /WebReport/ReportServer design_save_svg operation that allows unauthenticated attackers to write arbitrary files via the filePath parameter. Attackers can send a POST request with directory traversal sequences in filePath and a __CONTENT__ payload to write a JSP webshell and achieve remote code execution. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-14.
