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\u00a0executes 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."}, {"lang": "es", "value": "El cliente servereye (tambi\u00e9n conocido como sensorhub, t\u00e9cnicamente ClientAgentContainerService) versiones 20.15 y anteriores son vulnerables a la escalada de privilegios local.

Debido a restricciones de acceso insuficientes en este directorio, un usuario est\u00e1ndar local puede crear el archivo disparador y proporcionar una ruta a un directorio que contenga instrucciones JSON maliciosas. El servicio posteriormente ejecuta la utilidad UpdaterAction.exe con privilegios de SYSTEM, que analiza las instrucciones y realiza una copia de archivo no validada desde un origen controlado por el usuario a un destino de sistema protegido (por ejemplo, sobrescribiendo un binario de servicio).
