Summary
Vulnerability reported (CVE-2026-14551). Successful exploitation can lead to full system takeover.
Original description
The description as published by the source.
The servereye client (also known as sensorhub, technically ClientAgentContainerService) versions 20.15 and earlier are vulnerable to Local Privilege Escalation. The high-privileged service SE3Recovery (EmergencyRecoveryService.exe), running as SYSTEM, periodically monitors the directory %ProgramData%\ServerEye3\update\ for a trigger file named "update_available". Due to insufficient access restrictions on this directory, a local standard user can create the trigger file and provide a path to a directory containing malicious JSON instructions. The service subsequently executes the utility UpdaterAction.exe with SYSTEM privileges, which parses the instructions and performs an unvalidated file copy from a user-controlled source to a protected system destination (e.g., overwriting a service binary). This leads to full system compromise as the service automatically restarts the overwritten binary with SYSTEM privileges.
