CVE-2025-54307
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA path traversal vulnerability in Thermo Fisher Torrent Suite Django application 5.18.1 allows authenticated low-privilege users to write arbitrary files via the /configure/plugins/plugin/upload/zip/ and /configure/newupdates/offline/bundle/upload/ endpoints. The plupload_file_upload function uses the user-controlled filename parameter without sanitization, enabling attackers to use '../' sequences to traverse directories and overwrite executable files like pdflatex, leading to remote code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Torrent Suite versionCheck the installed Thermo Fisher Torrent Suite version via the web UI footer, system information page, or by querying the package manager if SSH access is availableAffected if the installed version is exactly 5.18.1
-
Confirm file upload endpoints existAttempt to access the URLs /configure/plugins/plugin/upload/zip/ and /configure/newupdates/offline/bundle/upload/ through the Torrent Suite web interface or check the Django application routing configurationAffected if these endpoints return a file upload form or accept POST requests rather than a 404 error
-
Verify low-privilege user accessLog in with a standard authenticated user account (non-admin) and attempt to access or use the upload endpoints at /configure/plugins/plugin/upload/zip/ or /configure/newupdates/offline/bundle/upload/Affected if a low-privilege authenticated user can reach these upload endpoints without receiving an access denied error
-
Inspect upload function implementationExamine the Django application source code for the plupload_file_upload function, specifically looking for filename parameter handling without sanitization of '../' sequencesAffected if the code uses the filename parameter directly from the request without stripping or rejecting path traversal characters
-
Check for unexpected file modificationsVerify the integrity of executable files in common paths (such as /usr/bin/pdflatex or similar LaTeX executables) by comparing file hashes or checking for recent modification timestampsAffected if executable files like pdflatex have unexpected modification dates or altered file hashes indicating potential overwrite
A user is affected if they run Thermo Fisher Torrent Suite version 5.18.1 and have authenticated low-privilege users who can access the file upload endpoints without proper path traversal validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation and sanitization for filenames in file upload functions - strip or reject path traversal sequences ('../'), use only whitelisted characters, and apply basename() to extract safe filenames. Additionally, restrict file upload permissions to only necessary high-privilege users and validate all uploaded file content before storage.
