Security readout for executives and security teams
DeskTime Time Tracking App versions before 1.3.674 may accept a fake update because TLS certificate checks were improper. An attacker already positioned on the network path could provide a malicious executable during update checking, leading to code execution with the logged-in user’s privileges. Exposure is limited to endpoints running DeskTime Time Tracking App before 1.3.674, especially on untrusted, shared, or interceptable networks. Organizations using DeskTime broadly on employee workstations should treat this as an endpoint hygiene and supply-chain update risk. Address in normal patch cycles, with faster action for mobile workforces or high-risk networks. The business risk is unauthorized user-level execution through a trusted productivity tool, but exploitation requires network-path positioning. Mitigation focus: Upgrade DeskTime Time Tracking App to version 1.3.674 or later.; Download updates only from DeskTime’s official download page.; Prioritize laptops and endpoints using public or unmanaged networks..
