Title
Weak File Name Generation in vsDesk
Summary
The application generates uploaded file names using a weak and predictable method based on the request timestamp. This allows a remote attacker to accurately guess or brute-force the generated filename within a short time window. An attacker can successfully locate and access uploaded files, which can be used to facilitate further attacks.
Apply patch from vendor https://vsdesk.ru/ . Versions 14.0101 and on have the patch.
