CVE-2025-14602 PUBLISHED

Weak File Name Generation in vsDesk

Assigner: Kaspersky
Reserved: 12.12.2025 Published: 20.08.2026 Updated: 20.08.2026

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.
