Detailsinfo

A vulnerability was found in FanRuan FineReport 9.0. It has been classified as critical. Affected is the function design_save_svg of the file /WebReport/ReportServer of the component Design Save Svg. The manipulation of the argument filePath with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.
