) Missing Server-Side File Extension Validation in vsDesk

Published Aug 20, 2026 · Updated Aug 21, 2026 · Assigned by Kaspersky

Description

An issue was discovered in vsDesk v14.0101. An authenticated attacker with administrative privileges can bypass client-side file validation in the "Import via CSV" component due to a lack of server-side validation. This allows the upload of an arbitrary file, which can lead to Remote Code Execution (RCE) within the context of the web application. 
Apply patch from vendor https://vsdesk.ru/ . Versions 14.0402 and on have the patch.
