What it is

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.
