Path Traversal in rConfig Before 8.2.13

Executive Summary

This is a path traversal vulnerability in rConfig versions before 8.2.13. Authenticated users can exploit it by manipulating the filename parameter in the export download endpoint with directory traversal sequences like '../'. This allows them to read arbitrary files outside the intended export directory that the application can access.

Detection Guidance

To detect this vulnerability, check rConfig versions prior to 8.2.13. Verify if the export download endpoint accepts crafted filenames with directory traversal sequences like '../'. Test by attempting to access sensitive files outside the export directory using manipulated filename parameters.
