CVE-2025-67728 Details
Description
Fireshare facilitates self-hosted media and link sharing. Versions 1.2.30 and below allow an authenticated user, or unauthenticated user if the Public Uploads setting is enabled, to craft a malicious filename when uploading a video file. The malicious filename is then concatenated directly into a shell command, which can be used for uploading files to arbitrary directories via path traversal, or executing system commands for Remote Code Execution (RCE). This issue is fixed in version 1.3.0.
A critical OS command injection vulnerability allowing remote code execution has been identified in Fireshare versions through 1.2.30. This vulnerability arises from the application's handling of uploaded video files. The filename, which can be crafted by the user, is directly concatenated into a shell command without proper sanitization. This unsanitized input can be exploited to traverse directories and upload files to arbitrary locations, or to execute system commands, achieving remote code execution. The vulnerability is present in several endpoints, including '/api/upload' and '/api/uploadChunked', both of which require authentication, as well as '/api/upload/public' and '/api/uploadChunked/public', which allow unauthenticated access if the Public Uploads setting is enabled.
Users can update to Fireshare version 1.3.2 or later, where this vulnerability has been patched.
