Vulnerability from fkie_nvd - Published: 2026-04-28 09:16 - Updated: 2026-10-07 09:10
Severity
4.8 (Medium) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N
Summary
Due to improper TLS certificate validation in the DeskTime Time Tracking App before version 1.3.674, attackers who can position themselves in the network path between the client and the DeskTime update servers can return a malicious executable in response to an update request. This allows the attacker to achieve user-level remote code execution on the affected client.
