What to do

AI-suggested

To mitigate CVE-2025-54307, organizations should immediately restrict access to the vulnerable upload endpoints to only trusted administrators and monitor for unusual upload activity. Implement strict input validation and sanitization on all filename parameters to prevent path traversal, including rejecting filenames containing directory traversal sequences or unexpected characters. Employ allowlisting of file extensions and enforce storage of uploaded files in isolated, non-executable directories. Patch or upgrade the Torrent Suite application as soon as a vendor fix becomes available. In the interim, consider disabling the vulnerable upload functionality if feasible. Monitor server logs for suspicious subprocess executions, especially involving pdflatex or other executables. Use application-layer firewalls or web application firewalls (WAFs) to detect and block exploitation attempts. Conduct regular audits of file system integrity and implement endpoint detection and response (EDR) solutions to identify anomalous behavior indicative of compromise.

Description

An issue was discovered in the Thermo Fisher Torrent Suite Django application 5.18.1. The /configure/plugins/plugin/upload/zip/ and /configure/newupdates/offline/bundle/upload/ endpoints allow low-privilege users to upload ZIP files to the server. The plupload_file_upload function handles these file uploads and constructs the destination file path by using either the name parameter or the uploaded filename, neither of which is properly sanitized. The file extension is extracted by splitting the filename, and a format string is used to construct the final file path, leaving the destination path vulnerable to path traversal. An authenticated attacker with network connectivity can write arbitrary files to the server, enabling remote code execution after overwriting an executable file. An example is the pdflatex executable, which is executed through subprocess.Popen in the write_report_pdf function after requests to a /report/latex/(\d+).pdf endpoint.
