Incorrect Access Control in AMAG Technologies Symmetry Edge Network Door Controllers

Secureworks Security Advisory 2017-001

December 9, 2017

Advisory Information

  • CVE: CVE-2017-16241
  • Severity: High
  • CVSS v3: 9.3
  • Discovered by: Mike Kelly and John Mocuta of Secureworks

Summary

Incorrect access control in AMAG Technology Symmetry Door Edge Network Controllers enables remote attackers to execute door controller commands (e.g., lock, unlock, add ID card value) by sending unauthenticated requests to affected devices via serial communication over TCP/IP. By monitoring TCP network traffic between the legitimate AMAG Symmetry SMS physical access control server and the EN-1DBC and EN-2DBC networked door controllers, Secureworks researchers were able to reverse engineer the basic data structure of the network communication.
