Technical details
The vulnerability is a missing server-side file extension validation flaw in vsDesk v14.0101's "Import via CSV" feature. The application relies solely on client-side validation to restrict file types; an authenticated attacker with administrative privileges can craft a direct HTTP request or disable client-side checks to upload arbitrary file types (e.g., PHP shells) to the web server. No server-side verification of file extensions or content-type occurs before processing. Successful exploitation leads to remote code execution in the context of the web application helper process. The issue was fixed in version 14.0402 and later, with enhanced server-side validation and relocation of temporary CSV files to a protected directory.
