AI-suggested

  1. Immediately audit and restrict write permissions on directories where ABP and AES services are installed, ensuring only administrative users have write access.
  2. Monitor the installation directories for unauthorized DLL files or changes, using file integrity monitoring tools.
  3. Until official patches are released by ASUSTOR, consider disabling or stopping the ABP and AES services if they are not critical to operations.
  4. Implement application whitelisting to prevent unauthorized DLLs from loading.
  5. Use endpoint detection and response (EDR) solutions to detect anomalous process behavior indicative of DLL hijacking or privilege escalation.
  6. Educate local administrators and users about the risks of installing or modifying software in insecure directories.
  7. Once patches are available, prioritize their deployment across all affected systems.
  8. Regularly review and update security policies related to NAS device management and service installations to prevent recurrence.

Description

When the service of ABP and AES is installed in a directory writable by non-administrative users, an attacker can replace or plant a DLL with the same name as one loaded by the service. Upon service restart, the malicious DLL is loaded and executed under the LocalSystem account, resulting in unauthorized code execution with elevated privileges. This issue affects ABP and AES: from ABP 2.0 through 2.0.7.9050, from AES 1.0 through 1.0.6.8290.
